    The story of how I and two fellow wheel riders became lost in the mountains and lived to ride another day. As I begin this, it must be said that I'm the one with poor judgement in this story. Well intentioned, but... The Cogswell Dam, as I've previously written about, is a gorgeous area to ride an EUC. It's basically a canyon ride on the northern side of a mountain ridge. I've ridden it twice before. Throughout this region are countless trails, large and small. One of the most well known is a four wheel drive capable trail called the Rincon Shortcut OHV Trail. It stretches along the southern side of the ridge that is shared with the Cogswell Dam. The Rincon trail-head starts about an 1/8 mile south of the Cogswell Dam trail-head. Up in the mountains there is a connection between the two, and that's what I've been itching to try. Complete the approximately 30 mile loop that joins the two trails. So I coordinated a group ride for Saturday morning, and my long time riding buddy @jrkline was the first to commit to the ride and not too long afterwards @Ando Melkonyan eagerly committed to the adventure (he had his newly acquired ACM). We were to leave by 9:30am, traversing the southern (Rincon) route first, taking advantage of the coolness of the morning air. Eventually we would meet up with the Cogswell Dam trail high up in the mountains and return by way of the shaded northern trail to avoid the extreme heat of the day. Oh, and today was the peak of a mini heat wave in Southern California, where the temperature was predicted to be in the low 90's. Maybe we should have brought more water. Hmmm. @abinder3 joined us at the very beginning. He didn't have time for the entire route (regardless of his reasons that was a good decision in hindsight) and therefore was just going to ride to the dam and back, about a 20 mile roundtrip. But it was nice that we could all meet at the beginning and share a few stories before we went our separate ways. In the picture above, from left to right: @abinder3 (Allen), @Ando Melkonyan, @jrkline (Jeff), and myself. Don't we look happy - if only we knew what was forthcoming I had my Monster which I had previously ridden here twice before. Jeff had the FrankenACM - I know, I know, his world famous 2040wh ACM. As would be demonstrated throughout the day, his ACM never fails. It may not be pretty but it's a faithful workhorse. And Ando brought his 3 week old ACM with a 2-1/2" tire that he managed to fit on the wheel. He had to cut away parts of the shell to make it fit, but he turned it into a really nice trail machine. We finally began our journal and after a few hundred feet wished Allen well as he exited for his trail head. We continued on the two lane highway until we came upon the locked trail gate, representing the entrance to our grand adventure. After bypassing the gate we began our journey in earnest. On a previous outing to Cogswell Dam I had ridden this part of the trail for a mile or so and was hoping the whole trail would be as I remembered. And for the most part it was, perhaps a little steeper in sections. But remember that this is a four wheel drive trail so certainly any path that a truck can take we can tackle easily on our EUCs. In this video you can see me struggling a bit as the ACMs zoom past me After a few miles of steady uphill climbing I was beginning to think that I should have taken my ACM too instead of the Monster. I've ridden my Monster a lot in the mountains now, but never for extended uphill pushes. We were on a trail that was to continuously climb for over 3500 feet. And this wasn't a paved road. It was gravel and sand mixed with large rocks and various ruts. So there was a lot of maneuvering involved, slips, slides, near stalls, and periodical jump-stops for the wheels. Although I have experience with the Monster and know that it's capable of ascending any hill that the ACM is, it does so extremely slowly and with much effort. As Jeff and Ando zoomed up the trail sections with hardly any physical effort, I was in a near constant crouch and heavy lean. Plus all of the effort required to steer the 70 pound Monster ... But I was hanging in there despite the ridicule coming from my fellow riders ;-) Fairly early on we had our first crash. I must say, anybody who wants to keep their wheel pristine should never do off-road trail riding. It's a messy business. My Monster requires a wide berth and although I always have my trusty helmet mirror, I have some rather large blind spots. Jeff was apparently unaware of these facts. As he was overtaking me on my left I was slowing sliding left. Our pedals locked and in the next moment we were both sprawled on the ground. Jeff's bloodied forearm and my bruised ego provided good entertainment for Ando :-) Here's a couple pictures of the aftermath: We continued the long climb, but I was getting tired. At one point Ando offered me his ACM while he pushed forward with the Monster. And then he proceeded to demonstrate a new technique (to me) for getting the Monster up hills fast. Jeff and I had great fun watching this and I think Ando was having fun to. It looked like he was riding a horse, but indeed it really moved fast. When I started riding the Monster again I used this technique and it really helped. But it was still hard on the body because of the lean, and steering was proving difficult. Eventually I discovered that if I was in a squatting position and squeezing the wheel between my knees, AND using my knees to force the wheel forward, the Monster really moved. This was exhausting however. We were still having a good time, enjoying each others crashes and Ando's music Somewhere near two hours we finally arrived near the peak. I was beat. Now we needed to find the trailhead that led back down to the Cogswell Dam. We came across a lone mountain bike rider that pointed us in the general direction that we needed to take to begin the descent to Cogswell Dam. In the following thumbnail you can see the Dam far below us. Here is where I made the fateful mistake of picking the wrong trail. It went down and looked to be in the general direction, so let's go for it. I really should have spent as long as I needed to be sure, but in the back of my mind I figured if it was wrong we'd probably realize it fairly soon and just backtrack. What I didn't take into consideration was my failing body :-( As we proceeded down this trail it slowly got sketchier and sketchier. First there were small dead falls (trees that fall across a trail) and then bigger and bigger ones where it took minutes to carry and or drag the wheel across. I was getting weaker. I had no more food and none of us had any more water. Remember that I said it was going to be in the 90's today. I felt like I was beginning to get symptoms of dehydration - shaky legs and arms and extreme fatigue. I could only ride 20 feet before I would loose control and had to stop and rest for a few minutes. By this time I had a few more rather severe falls which further hampered my ability to ride the wheel. Besides my difficulties, it had become clear that we were somewhat lost. This was certainly not the trail to the Cogswell Dam. I could simply not go further. At this point I was with Jeff. Ando had explored further along the trail and when he returned he said that he found water (we could hear a stream in the distance below). You don't know how excited I was to hear this. I felt that maybe if I got some water I may recover enough to continue at some level. Jeff took my empty water bottle and disappeared down the trail to return with water. I was feeling a bit mentally refreshed. While Jeff was away Ando and I tried to figure out exactly where we were. I had offline Google maps in my phone and a Garmin 60CS handheld navigator. BTW, GPS reception was not great within these mountains. But we eventually determined our exact location. Miles from the trail that we should have taken. I had arrived at a difficult decision. Like the sailboat captain in the middle of the ocean that grapples with the decision to press the emergency beacon, knowing that when he does so he will be rescued but his boat will be left behind, gone forever. But I knew that I could not continue back uphill to retrace our steps by a few miles and then down another 15 miles. Impossible. So I told Ando to leave me and get back to the area where we made the bad turn. In that area there was a line of site to the greater Los Angeles area and there was cell phone coverage. "Tell them that a person was suffering from exhaustion and dehydration. Call 911". Now by this point at least 15 minutes had passed and Jeff probably should have returned within 10 minutes since Ando knew the water was only 5 minutes away by wheel. But we continued to wait. While doing so Ando took my Monster and rode/carried it up the trail past a few of the sever dead-falls. And then walked back. Amazing, and as you'll learn in a bit, very important that he did so. Still no Jeff. Instead of sending Ando to look for Jeff I suggested that he go the other way, and I'll wait for him. So Ando disappeared with his ACM and I was alone in the middle of what felt like nowhere. I think it was about 3pm at this point. I lay on the ground and was anticipating a bottle of water with great joy. Maybe another fifteen minutes went by. Nothing. Then I started thinking, "Maybe something happened to Jeff. Was there an accident. Did his ACM break". I slowly started walking down the trail. 20 steps and then lay on the ground to recover. 20 steps, lay on the ground. I did this for maybe 15 minutes but realized that if he was hurt or the wheel was broken I was in no condition to help. And I had told Ando that if possible I would try and walk back to the trail junction at the top of the mountain. So I abandoned Jeff and ever so slowly started walking up hill. 20 steps, lay on the ground, ad nausea-um. I still had hopes that Jeff would return with water. I would have given away my Monster for water at that point. It really was horrible. At this incredibly slow pace I managed to get past the large dead-falls. I never would have been able to get my Monster past these obstacles in my condition. Eventually I found my Monster and could not believe how far Ando had taken it for me. I then proceeded to push it and myself up the trail, in spurts of low speed energy. A trolley handle may have helped, but just the effort of pushing the Monster and walking was too much. After maybe an hour I decided to abandon the Monster, knowing that I would never see it again. I wasn't worried about someone finding and taking it. First, nobody sane travels this impassible trail, and if someone did they wouldn't know what it was, and at 70 pounds I don't think they would try and carry it out. No, I would never see it again because I would never be able to get in here to recover it. That would entail hiking 15 - 20 miles which is a long hike on flat ground. I just didn't see myself being able to do that. I marked the location where I did leave it, in my Garmin 60CS thinking that I would post to Facebook and the Forum with the coordinates and anybody who thinks they could retrieve it could keep it. No bad feelings on my part. Anyway, it was load off my mind when I fully committed to never seeing it again. Let that be a strong reminder to what not to do in the future. I continued the painfully slow march. I was worried for my health because I know dehydration can be bad. But I tried not to exhaust myself too much. Walk for a few minutes and then lay down. Walk, lay down. Minutes turned to hours. I was thinking maybe if I eventually got to that magic "cell phone coverage" area that I could call 911 in case Ando wasn't able to. It's amazing what goes through your mind when you can't communicated with people who are trying to help you.What happened to Jeff? Did Ando make it out yet? Knowing where we had last all been together I was thinking positive and assuming that Jeff decided to explore that path beyond the river and went so far that he decided not to return with water. I knew that particular trail wound its way back up to the top of another mountain range to the 2 freeway which then led to civilization. So if he got out he would be able to call. But I had my doubts that we would have enough remaining power to climb another couple thousand feet and maybe 20 miles. I kept think that if I get rescued I'm going to have to tell them about Jeff so that they can search for him next. After maybe 3 hours I came across these maintenance trucks and construction equipment that we had passed on the way down. I opened every truck and door I could get into and FOUND WATER. Two old water bottles with maybe a 1/3 full of water each was an amazing find. First I sniffed it to be sure that they weren't storing fuel and then guzzled them down. Water had never tasted to good. Although it did not help with the exhaustion in my legs, it did help with the thirst and made me feel like I actually wasn't going to collapse somewhere up here in the mountains. I continued to walk, imagining what might be happening with Ando and Jeff. And then of course I was worrying about my wife because in the absolutely worst case I probably should have been home by now. But there was nothing I could do. She did know the general trails that we were taking (at least I got one thing right), but it would probably be very dark before she pulled the trigger and called 911. So I was still prepared for a very much longer day and night. Dusk was approaching when I started to hear a helicopter somewhere in the distance. That was the first mechanical sound I had heard for hours. I thought I heard a plane too. I did see the helicopter at one point but it was miles in the distance. Amazingly I had made it back to trail junction where we made the bad turn. And then I heard and saw a large search and rescue type helicopter hovering over me, but very high. I was in an area where there were power line towers (thus the maintenance equipment found earlier) plus I'm sure they generally stay far above the trees. I waived both my hands for a little bit and then it moved off to the distance a bit and hovered again. Then it left. "Well, that's it. I've been found and now help will be on the way". That was a huge psychological lift for me. So I continued to walk, and walk, and walk. It was now totally dark, after 8pm. Fortunately I had small pen flashlight so I could see the path in front of me. No longer fearing collapse from dehydration I could start contemplating coming across bears or mountain lions, both of which live in these mountains. What joy! I then spotted a brief flash of light followed shortly by a truck rounding the corner ahead. You can imagine what I thought at that sight. It eventually slowed to a stop beside me and I was asked my name (I guess they didn't want to pick up the wrong guy) and let me in the truck. There were four uniformed men in there, all volunteers for the Sierra Mountain Search and Rescue. They gave me all the water I wanted and bagged peanuts. Life was good. Shortly after I got in the crowded vehicle I asked if they happened to know about any other ..., and before I could complete the sentence they told me that all three people have now been accounted for. So Jeff was alive ;-) I assumed Ando was good because otherwise I probably wouldn't be sitting in the truck at the top of the mountain. Now get this, they then asked me, "do you want to go get your 'bike'?" Are you kidding me? I tried to suggest that I didn't want to put them through the trouble (I really didn't), but they insisted. They said that they were already up there so why not. It probably took another half an hour and a locked gate to get within a few hundred feet of where I left it. The last bit had to be walked since the trail conditions were too severe for the truck. So I actually got my Monster back. It felt like I just received a new wheel because in my mind I given it up for lost. As we drove down the mountain for the next 1-1/2 hours I learned that Jeff had been recovered on the 2 freeway, and Ando was the one that called it in. Eventually I met up with Jeff as we were brought together at the base of the mountain to be driven back to our vehicles (20 miles away). There Jeff told me how he amazing made it back up to the highway on the other side of the mountain range and then down towards town, almost on a zero battery charge. His 2040wh ACM truly has been an amazing wheel. I also learned from the rescuers that the helicopter had not seen me! Amazing. The guys said that in the future you should lay on the ground and move, otherwise all they see from above is a head, and that's hard to distinguise from everything else. So they found me based on what Ando was able to tell them. You can read some of what Jeff encountered here: And then when I finally got home around midnight (having left in the morning at 8am) I eventually read about Ando's experience which was amazing in itself. His ACM has also proven to be an amazing wheel. Essentially going 10 miles down mountain trails with almost no battery power remaining. You can read is account here: And here is the dam (it was not Cogswell after all) that Ando got to: And the 911 help that arrived after he made the call So there you have it. I think none of us will forget this ride. It's been four days and I'm still having difficulty riding, which really surprised me. When yesterday I hopped on my KS14C for a short utilitarian trip I almost crashed as the wheel was very wobbly. I had a hard time turning. It was then that I realized that my legs were still weak and uncoordinated. Amazing. Although I declared that I wouldn't do this again, time heals all wounds ;-) I know Jeff is up to doing it again, and maybe Ando will be to. We will be better prepared next time. More water, food, maps, only ACM's or the like, and a bigger breakfast. Oh, and Jeff says he'll bring his ham radio (which hopefully will not be needed). I hope you enjoyed my little adventure story

Here there is a full percentage of marriage for any service call due to electronic or electrical problems (here, mechanical damages and tire punctures are not taken into account) The percentage of rejects from sold devices during the period February-July 2017 is indicated. In brackets, my comments are highlighted by a frame. Inmotin: V8 - 4.8% (excellent quality: wow :, there were a lot of sales) V5, +, F - 5.88% V3c, pro, s - 7.8% KingSong KS14B - 3.33% KS14C - 15% (due to low sales, as the model changed to 14d) KS14D - was not in the service (selling was enough) KS16 - 7.33% KS16S - 1.12% KS18 - 17,24% (transition to sports) KS18S - was not in the service (sales were moderate) GotWay MCM4 - 18.57% ACM 680,820 - 36,6% ACM 1300 - 35% (a small number of sales, according to my personal feelings this is the best of the gothweb) Msuper 680,820 - 11,11% (the average number of sales, here statistics is more visible) Msuper 1600 - 36.98% (every 3 users of a pregnant soup met in the service, the statistics could be a little lower, because in my memory there were repeated calls for the same problem) Monster - 23.4% (a small number of sales) 2. And here now I will show the statistics of the marriage in percent only on the controllers and sensors of the hall. Inmotin: V8 - 1,97% (the standard, as I already said) V5, +, F - 2.71% V3c, pro, s - 2,12% KingSong KS14B - 2% (reference wheel standard) KS14C - 10% KS14D - was not in the service (selling was enough) KS16 - 3,33% (the percentage of the marriage is halved due to the fuse on the board) KS16S - 1.12% (reference) KS18 - 6.89% (the percentage of rejects decreased threefold, 18 of the usual words had problems with the charging connectors and balancing the battery) KS18S - was not in the service (sales were moderate) GotWay MCM4 - 14.28% ACM 680,820 - 26,6% ACM 1300 - 14.28% (all problems are of the same type - controllers or hall sensors) Msuper 680,820 - 9,25% Msuper 1600 - 34,24% (every 3 users of a pregnant soup met in the service, the statistics could be a little lower, since in my memory there were repeated calls for the same problem) Monster - 23.4% (a small number of sales) Final output: Let's break our conclusion by brands. - Inmotion is very good with the quality of monocols and this statistics confirms this. Sales were many and the statistics complete. Inmotion keep it up, there is much to grow. But in general. Well done. - KingSong - the average percentage of rejects for old models (14c, 16 and 18). And the phenominal results for the new sports versions. I also want to note separately 14B - the best wheel for entering the monocoque tusovka in relation to quality. You pay a little, you drive sadly, but not in service: laugh:: laugh:: laugh: - Gotway - it's bad ... We need to work on quality. No model can compete in quality with either kingsong or inmoshenom. There are weak attempts at Msuper680, 820, but not enough. Msuper1600 - generally horror. 84B and the controller from gothve is a nuclear device. As I have already written many times - buying goths makes sense only when you understand what you are taking. Exceptionally speed. If you are not about the actress, unfortunately, goths should not be considered. I very much hope that the gothwa will draw its quality to the level of the standard set by Inmotion and KingSong. P.S. If you have something else to count or see - ask questions in the topic - I will try to find answers to them. Since October 2017, we will have a new program for recording faults and everything will be much better and clearer in it.

    Hello All, It's been awhile since i've been on here but thought why not share my thoughts on this wheel, I was lucky to get. It's a prototype that was sent to me by Gotway America to keep. I decided to share my experiences with everyone. www.Gotwayamerica.com I also want to thank @houseofjob for helping me put this video together! I cant give an review since I just got it and want to spend time with it. Here are some specs. Motor - 1900watt Battery - (this model) 1020wh Built in Trolley - yes Light Belt - yes (reminds me of the ninebot days) Weight - 42.8 lbs Brighter head light compared to previous models. 4 pin charger - same as the Msuper V3s+ 84v Max speed so far - 30mph! Built in dual fan- silent could barely hear it. I feel like this wheel have some type of shock absorption.. Not sure how to describe it but it goes over cracks and bumps with easy. Very comfortable to ride although when trying to ride on 1 leg i'm experiencing a slight pain on my shin. Not sure if its something I have to get use to or is it because of the thin padding that was placed there. I created a video that should help with how it looks and test rides. Hope you guys like it. Also motherboard is now placed on the top of the wheel instead of the usual side next to the batterie. Cables seems to look well connected here are some pics. Again i hope this helps.

    Today I received my Monster (I was expecting it next Monday). Shipped from Speedyfeet on Sunday to California. Can't beat those delivery times. So you can see me with my Monster and 1300wh ACM that I got 3 days ago. Two new wheels within a few days - I'm not sure what to do Before I continue with my Monster ride observations I feel that I need to make this statement: I hereby formally bow down to the Gotway Gods Ian (Speedyfeet) had pre-charged the Monster so when I took it out of the box (and gave myself a small hernia in the process) I had an 80% charge. That meant only one thing - an immediate test ride. I used my existing old Gotway app to configure it: 1st & 2nd alarms off and tilt-back off. It's nice that I've been able to use my original Gotway app to configure all of these wheels. And the Wheellog app (and Pebble watch connection) work perfectly with these new wheels. When I climbed aboard (an apt description) and started riding I thought to myself, "what have I gotten myself into"? This thing is a beast and when you first start, it feels totally unwieldy. Turning as you do with a normal wheel does nothing - it keeps going straight. Turning the Monster is all about weigh shifting and hips to shoulders. I will say that once you get use to this way of turning it is a piece of cake. I can literally turn with the same agility as my ACM, but the body movements are very different. The problem can be that as you're riding and suddenly need to turn you apply your normal turning techniques and the Monster just ignores you So after a 25 mile ride today my knees and lower legs are hurting because I kept falling back into my old ways. Clearly this will improve. But I did ride 25 miles today. After about an hour everything was really clicking and it no longer felt unwieldy. I'm probably going to run out of superlatives trying to describe my riding today. I rode a river trail that I enjoy, a park with lots of dirt/sand trails, and sidewalks in town. The Monster eats anything in its way. I'm serious. I rode over bumps, thick mud, sand, whatever. It just takes it and doesn't toss you around. Deep ruts in the trails? - the Monster laughed at them. Hitting some of them in my ACM would have thrown me from the wheel. I like to carve when I ride and that was very enjoyable with the Monster. Weaving in and out of obstacles on the sidewalks was easy. I climbed a couple of very steep inclines and there was no problem. Feels like my MSuper - you have to really lean into it and have faith that it's not going to dump you. My ACM on the other hand climbs inclines much easier. Acceleration and braking feels like the MSuper, but a tad more sluggish. Today I had one hard brake that I had to apply to avoid missing my intended turn. I managed the brake and turn successfully but it was a near miss. I think it's best to plan your brakes well ahead of time with this wheel I must say that I think the Monster has the potential to be a dangerous wheel . Why? Speed. Prior to the Monster I felt that I had the fastest wheels available (ACM and MSuper). I typically ride my ACM between 17 and 20 mph, sometimes going up to 22 for short periods. Feels very fast. The Monster? It laughs at 20. Seriously! For half my ride today I would catch myself looking at my watch (Pebble) to see that I was going 22mph! For awhile I was going 25mph and here's the thing; it didn't feel dangerously fast. 25! I was feeling very comfortable going 22mph whereas on the ACM it feels like you're pushing it. The Monster is so stable and has so much reserve power that it's a pure joy to ride fast. I was riding 20mph on some trails! I never heard the 3rd alarm today. So I have to say if you love going fast and eating up any road or trail in your way you will love the Monster. I think it's the most amazing wheel ever produced. I'm very serious. No, I wouldn't recommend it as your only wheel because lets face it, it's a beast. But in the context of trail & street riding it's amazingly fun. I can't wait to take it up into the mountains this weekend. I'll be posting a video review and ride video sometime in the next week.

    It's with sad news that I'm here to say that my brand new (now scratched to hell) MSuper V3s+ is afflicted with the now infamous Gotway oscillation syndrome. I had just picked it up personally from @Jason McNeil a couple of days ago while he was out in California inspecting his latest delivery from Gotway. He's a great guy to hang with btw, and we (Jason, myself, and @Sven) had a fun little ride in some local hills. Andy, you need to post that video you made! Of course I tested mine a day ago by riding (slowly - which is key to remember) over various bumps, curbs, etc. No problems. Yeah! But this morning was my first opportunity to take it for a serious ride. I setup my camera and filmed a short mini-review introduction to my new MSuper (God I wanted to love this wheel) and then took it out on the road. As you'll see in the video below, about 3 minutes into the ride I'm on a sidewalk, probably not going faster than 15mph. I travel across a street and up on to the sidewalk, and that transition was enough to cause it to instantly oscillate and throw me off the wheel. My take away is that the wheel has to be traveling at a fairly good clip for this to happen. But as you can see, I was not exactly traveling at an extreme speed. Jason is screwed with his recent shipment, and I must say anyone who has received a unit within the last month or so is risking their skin if riding the wheel faster than 10mph. Even though I say in the video that I'm probably going to ride it, I'm not. As I rode home I couldn't make myself go faster than 10mph for fear of the oscillation. There is zero warning. There's absolutely no fun riding a wheel under those conditions. I have no clue how Gotway is going to prove any recent wheel delivery is without the problem. They clearly lied to Jason regarding his shipment, and he must be one of their best dealers. When I get a new control board (I assume), how will I know Gotway did anything. Who wants to gear up and ride 15 - 20 mph into a bump to test it? I'm sure I'll be more open to the idea after a few days, but not now. My left wrist and hand is getting worse as I type this Well guys, I only have my Monster and KS14C to ride now, and summer months are upon us. What a bummer. Enjoy the video The thumbnail is 1 second before the crash - ouch.

    A little story some of you may find interesting... Yesterday I was taking a mid-afternoon ride along the beach on my KS14C. Beautiful Southern California day. As I was approaching the Hermosa Beach Pier I spotted two wheelers in the distance! Amazing. In the year that I've been involved with EUC's I've never come across a fellow rider, let alone two. As I approached from behind (they were traveling at a leisurely pace) I saw that that they were a young couple, in their early 20's I would say. He was riding an MCM and she was on a two wheeled Inmotion wheel. I smiled and waved as I rode past them. Needless to say they were really surprised. We stopped and chatted for a nice long time. The MCM was bought from Dion (@myfunwheel) and the Inmotion from @Jason McNeil (EWheels). All within the last couple of months. They had no knowledge of the forum and our local group rides that I organize. I think that I may have found a couple of new recruits. Hopefully they will join the forum. Now Brian, he was a little frustrated with his wheel because it would always tilt-back, and was about as fast as the Inmotion (i.e., not very fast). I took it for a little spin and sure enough, tilt-back must have been set to 10mph or less. I whipped out my phone and reconfigured his wheel (with his permission of course). Immediately he saw a huge change in his wheel. It felt like he just received an updated EUC. He looked very happy as he started zooming around (I turned tilt-back off). We rode together for a bit more before we went our separate ways. I'm hoping to see them during our meetup with @The Fat Unicyclist In hindsight I thought it must have been very unique from their perspective to have some guy pass them by on another wheel, stop, and reconfigure their wheel to make it perform much better, and then zoom away. I hope to have more encounters like this in the upcoming years

    It had to happen eventually. This morning I met Andy (@Sven) at Chino Hills State Park for an exploratory ride. Neither of us had ridden this area before. Andy had his Monster and I was riding my ACM today (it can climb any hill). The ride started nicely enough but we eventually started on the dirt and gravel trails. During on epically long very steep section Andy's Monster overheated with a resulting tilt-back, and within 5 seconds my ACM self-destructed. It was a long hike out In this video (thanks Andy for all the additional video footage) you can see the ride and where I crash and burn as the ACM gives out on me. Then, back in my workshop I open the ACM and show the carnage inside (massive amounts of melting connector housings and wires. Oh, and the control board is toast. Seeing the melted wires first hand (and my riding weight is 170 pounds) tells me that I will never again (until they make design changes) ride any of my Gotway wheels for extended (>15 seconds) periods up very steep hills. It's clear that the insulation isn't up to the task. Mind you, I'm talking very steep hills, where you are crawling up. Enjoy the video

    I love my Msuper V3. But: when things get wet and dirty, it has this nasty habit to throw everything up my back the road has to offer. Uhhh, I don't like mud slinging (even though it seems to become increasingly popular in politics). So, here is my solution: a 3D printed mudguard! Pick it from the print bed, peel off the brim, smack it on your Msuper and you're set to go! If you have access to a 3D printer (pretty much any one will do), download the model file from here http://www.thingiverse.com/thing:2083438, use up some 70 grams of ordinary PLA filament (< $2) and enjoy riding through Siberia in the fall. If not, google "3D Print Service" and find somebody, who prints it for you for less than $20. I put the file into public domain, so anybody can use it privat or commercially. I positively invite GotWay (happy New Year, @Linnea Lin Gotway & @Jane Mo! Does CNY come with New Year's resolutions, too?) and the nice distributors in this forum to use it. Give it your own branding if you like. And folks, please don't complain, if a distributor asks 50 bucks per piece - they have all those warranty obligations, can't exclude liability (like I do ) and still need to make a living... Here's my test ride today on Tempelhof airfield:

    @Jason McNeil has been out in California the last few days, re-flashing all the ACM's and MSuper's (40+ I think) before sending them back out to the customers. When I finally was able to get to his makeshift workshop with my MSuper, mine was the last one. It took about 10 minutes to open, remove the bluetooth module, plugin the Gotway firmware loader, and download the fixed code (which took maybe 5 seconds to download). This is an interesting aside. Gotway had originally told Jason that they had caught his shipment before it went out the door, and re-flashed all the boards. Fast-forward to now when Jason is re-flashing all of the wheels. The process involves taking a razor blade and slicing the silicon that is holding the Bluetooth module to the control board, so that the Bluetooth module can be removed. Jason discovered that about one third of his 40+ wheels had the silicon sliced. This means that Gotway fixed 1/3rd of Jason's wheels, shrugged, and decided to ship the rest without fixing. Who knows why. Maybe they had a deadline to meet and ran out of time, or the workers told management that everything was done so they could go home. Who knows, but it's rather amazing. I've ridden my fixed MSuper in the mountains above Los Angeles for about 45 miles between yesterday and today. Lots of fast, rough riding with bumps galore. No problems. My final test was to repeat the scenario that threw me off the wheel two weeks ago. Here's the video... Everyone who is receiving @Jason McNeil's wheels in the next week or so can rest assured that they have a solid wheel that can take abuse. I'm back to lovin my MSuper

    I am back from Las Vegas after attending the Consumer Electronics Show (CES) and here to report on EUCs as I did last year. Unfortunately the showings of EUCs has dramatically decreased from last year. Kingsong dropped out this year. Only EUC companies that were there were Segway (ninebot), Swagtron, and Jyro. Fastwheel and Airwheel were there too but they weren't even displaying any EUCs but instead focusing on skateboards and 2 wheel scooters. And I didn't see one EUC from any other cheap chinese brand. It's a telling sign on the poor general mass market state of EUCs. Even the companies that were displaying EUCs did not focus on them which I'll go into more here. Skip to the very bottom for videos. I bought my Msuper V3 and Kingsong 16A with me to Vegas. Shipped it by Fedex which the shipping wasn't too expensive. Would be much better to just take it on the plane.... but anyways on to the EUCs. Segway (Ninebot) So after ninebot bought Segway, they quickly realized that Segway has more branding power than Ninebot. Hence why officially Segway Inc. was listed for CES and not Ninebot. They were showing off the Ninebot One S1 and had a young kid ride it around in their booth. Unfortunately the old head honcho would not allow me to ride it at all even after signing their waiver to ride their products. He was basically an asshole to me about it and basically did not believe/trust me that I could ride an EUC. Even after he saw my gotway and kingsong, he argued back to me "Oh I see you already have wheels yourself, you don't need to try the ninebot"...... most arrogant stupid crap I've ever heard when the entire point of going to a show like this is to promote and sell your product. He also said they offer training on their large two wheels with handles Segway but not the S1. This furthers hammer home that there is no push to get EUCs on the mass market when the biggest company with an EUC actively shuts potential customers down test rides and instead offer rides and training for their non-EUC products. Segway just left a very bad taste in my mouth after that and now I'm more motivated to show off the capabilities of the EUC anytime I see a Segway rolling down the street now. Jyro So at the corner of the hall was this new American company called Jyro. They had a whole product line of scooters, one wheel skateboards, and EUCs. But all of their products are just Chinese OEM rebranding. And in the case of their EUCs, they were just the Inmotion V3 and Inmotion V5F. The main marketing guy even admitted that they were Inmotion products but that they adjusted the firmware of their wheels and that they have an app (which he wouldn't show me). Both wheels felt exactly like the regular Inmotion products though. Oh and no one at their booth could ride and show off the EUCs. One of their employees barely was able to ride the twin-wheel V3. Oh and their one wheel skateboard is basically a knock-off of One Wheel. SWAGTRON The people at Swagtron really have a lot of money and marketing going for them. They were one of the first ones to jump on the "hoverboard" craze by offering their "Swagway". With the implosion of "hoverboards" this past year, they really have doubled down on not only staying in the market but offer new revised "better" hoverboards and just new ridables which include their EUC, the "Swag Roller"..... which again is basically an InMotion V3. Although they did change it enough to where it does look a little nicer. They did get UL certification though which they proudly displayed at their booth. They also displayed their booth babes riding around on all their products (except for the EUC) and also had the hoverboard boy dancing group do their dancing routine on their hoverboards. Like Jyro, no one could ride the EUC. But after the dance group finished their routine, I showed those guys Damien Gaumet's EUC trick video and they were blown away by it and immediately started to try to ride the EUC. So maybe this year we might see a dance video featuring EUCs by them? Swagtron's EUC basically rode like the Inmotion V3. They said they were going to sell it for $400 but didn't have any plan to release it. Special Treats HONDA actually brought their self balancing seated "EUC" the uni-cub. I first saw this over 5 years ago and was excited to see it displayed and even more excited to actually ride it. it handled similar to an EUC but this one also balances left and right for you. Because of that, it is possible to strafe left and right but I was never able to fully strafe with my time on it. But it was still very easy to ride but with just a top speed of 4 mph. I almost overleaned the unit by testing its speed while another guy actually did bust his ass trying to do the same. Another fun treat was when I ran into RYNO Motor guys on the sidewalk outside of the Convention. First time I've even seen these in person although I didn't ride. It was very funny to see the size of the RYNO next to my Msuper V3 but knowing that the Msuper is much faster which a longer range. Even though it was cool to see the RYNO, it still represents an over-engineered product that will never see mass market adoption as a practical form of personal transport. SIDENOTE: As I was leaving from the airport, I saw a 3 wheel electric scooter about to board the plane. Talked to the guy on it and he was their to just transport it back home after CES. He wasn't using it for any disability. I asked him how he was allowed to bring it on the plane and he said that his brother took care of all of that. This product uses a lead-acid battery though so that may be the difference? And that was basically it as far as Unicycle-like devices at CES 2017. Got to meet Jason McNeil which is always a pleasure to meet someone else as passionate about EUCs as you. But hopefully that passion translates over the general public soon, if at all. There have been several threads on this forum already but we as an EUC community really need to do everything that we can to promote EUCs not just as a fun activity, but as an actual useful and practical personal transportation vehicle not for the future, but RIGHT NOW. That is why I ride not only on sidewalks but also on city streets with cars to show that I am no different than a regular cyclist on the road. It also helps encourage positive views in the minds of police and lawmakers to accept these EUCs on everyday life. I'll leave with two videos, one of EUCs at CES and one of us riding in and around Las Vegas.

    I'm going to collect my ongoing thoughts about this wheel on this page. I just finished my range test and feel that I can offer some solid opinions about this wheel. BTW, I'm somewhat of a Gotway fan (did I understate that ?), so bear that in mind. So here goes... I own a Monster, MSuper V3s+, ACM V2s, and KS14S, and have ridden just about every other mainstream wheel that has been produced in the last couple of years (group rides are great ). The Mten3 is the funnest wheel that I've ever ridden. Is it the fastest? No. Does it have the most range? No. But is it fun? My God is this a fun wheel During my range test I rode it mostly on paved trails and sidewalks, but did a fair amount of dirt trail riding and grass riding. When on the flats riding straight I was doing 15mph (24km/h). It was not struggling, but I did not feel comfortable going faster because the wheel is super-super-agile and therefore not very stable unless your road is perfect and there is no wind. My range test lasted 2 hours 15 minutes and covered 20-1/2 miles (33 kilometers). Tell me that is a respectable distance to cover on such a tiny wheel. Over 2 hours is a lot of fun time. My riding weight is under 170 pounds (77kg). For 18 miles (29km) I could do anything. Then under strong acceleration I started getting the beeps. The last ~mile was limp mode - 7mph (11.2km/h) or less. Unlike KingSong, Gotway lets you really have fun all the way to 15% battery (this is my only KingSong dig - sorry guys ). The wheel feels very solid when accelerating, and stops on a dime from high speed. At all times it felt that there was extra power in the tank. It really is like an ACM bottled up in a tiny package. When going up hills it has power, power, and power. With this Mten3 I finally feel like my feet are one with a wheel. It's OK when traveling at 15mph (24km/h), but is amazing below 10mph (16km/h). It feels like you are standing on a little ball that glides effortlessly wherever you think you want to go. Let me give you an example. When you're on a sidewalk and have to stop for traffic and wait until you get the walk signal, that's not the funnest of times is it? Either you're off the wheel or holding on to a post. Well not with this wheel. I actually found myself looking forward to getting a red light. I am not exaggerating! I can effortlessly do little 360 turns in the space of my body (I'll post some more video on this page later), and it's fun. If you can ride backward, this wheel is killer. I can do tiny pendulums all day long. So this wheel strangely is funnest when you're waiting. I'm doing tons of little 360's, pendulums, etc. The last couple of busy intersections that I crossed, I actually did a couple of mid-intersection 360's to give the people waiting a little show Effortless and very fun. I'm telling you guys, this wheel is no joke. You owe yourself to get one. I truly do not believe you would regret it. It would bring utter joy to your riding about town. And again, 18 miles (29km) of solid fun is very respectable. I'll post additional info on other features on an ongoing basis. I'm off for some night riding as soon as the wheel is recharged

    Uuuuh, this is gone be a long one ... but since you asked ... lemme try try to shed some light on the extent of quality assurance (QA) we may realistically expect from our wheels. And why I am rather surprised, that 9 out of 10 eWheels seem to work flawlessly. Visiting the GotWay fab in May 2016, I was expecting something more than what I had seen on the usual pictures. You know, those 4 long work benches showing GW wheels in various stages of assembly. But: that's pretty much it! There's a small office area with people working on PCs, a couple of soldering places with little else but a soldering iron and some reels of cables and adaptors and some side rooms with loose piles of motors or cartons with supplies or finished products readied for shipment. And, at the time, a single prototype of the new MsuperV3 kept in the directors office. I have not seen any test bed (like for example the stationary test rig of electro-sport.de), no sophisticated measuring equipment (like an oscilloscope), no specialized assembly setups (other than electric hand tools), let alone any automated machinery, robots or the like. I have probably seen like 15 people working on site and was told the staffing goal for 2016 to be 30 employees. Also notably absent: Signs with working instructions, parts lists, check lists, tables with spec limits or the likes - very basic measures of QA I'm familiar with from "back home". "Here's a picture of what it should look like. If your work result looks different, we likely got a problem". Now, I may not have seen everything or was occupied by other things as I got all excited when I was allowed to test ride the MsuperV3 prototype in between the assembly lines. But recent events seem to confirm my observations at the GW "manufactory". Speedyfeet reported receiving an entire delivery of Msuper3's with left pedals being mounted to both sides of the wheels ("What's wrong with this picture?"). A friend just took delivery of a new Msuper V2 this month: Bluetooth didn't work. He found the little BT "piggyback" board thoroughly glued in place on the main board (as it should be), but its connector pins were in the wrong position (indicating 1. a design flaw as such connections should be coded, 2. sloppy assembly without control steps and 3. the absence of functional testing of the final product). Speculation time: what QA-risks are we exposed to: 1. Product design: Other than the famous pictures of the small indoor incline test ramp used by KingSong and IPS, I have not seen any special testing setups. With any new design, I have to assume, that some dare devil test rider takes a prototype to the streets and off-road tracks and maybe some puddles of water. If it survives the abuse those test riders can come up with, it's ready for production. While it is touching to see an asian tester taking another person on his shoulders to approximate the weight of a "westener" during a test ride, this is of course worlds apart from systematic and reproducible testing under all conceivable usage and environmental conditions. 2. Component/final assembly: there might be different "shades of grey" between manufacturers, but I would be very surprised to find automotive like standards with any present EUC producer. This is the area, where exceptional dealers like @Jason McNeil, @1RadWerkstatt, Speedyfeet and others can help with additional checks of the products they receive. But frankly, we can hardly expect them to perform full functional testing and still sell at affordable prices. The ones moving higher quantities may be able to persuade manufacturers into higher QA awareness and efforts. 3. "Supply Chain Management": there's something very unique and fascinating about Shenzhen: the "Huaqiangbei electronics mall". Picture many, many warehouses, each one the size of a larger Macys department store and each one specialized on electronic components. Like an entire Macys for LEDs. Or logic ICs. Or passive SMD components (resistors, capacitors, etc.). And each of these warehouses is composed of a myriad of tiny stalls, stuffed all the way to the ceiling with, say, SMD reels with diodes. That's a "Maker's dream"! Just like we hit a grocery market with the recipe for tonight's dinner, you can go to these warehouses with a parts list for your ewheel controller PCB and come back home with all the components you need to produce 500 of them (and still money left for groceries). And I'm sure, you'll find an infrastructure of services to produce your PCB and mount the items from your shopping bag to it just as easily. (If you are interested in these amazing capabilities, the flowing boundaries between "Makers" and commercial production and the fascinating spirit that goes with it, I can recommend spending an hour here: https://www.youtube.com/watch?v=SGJ5cZnoodY). To me, this convenient electronics market place is both a huge advantage for rapid product development and a dangerous burden for quality management of the production. Since you cited Toyota's quality as a reference point: I worked for many years in the semiconductor industry, producing components for automotive applications. Quite regularly, we have seen audit teams of the big car makers turning both the entire production line upside down and also scrutinizing the IT side of QA. Many QA improvements were introduced as a direct consequence of those audits. And when the chips are delivered to such clients, a matching huge compilation of data from measurements and testing is transferred in parallel to the client. And there have been a number of embarrassing moments, when clients analyzed those data sets and pointed out weak spots in our production line, we did not find ourselves. Just two basic examples: Look at these 2 result sets from temperature testing. Both are perfectly inside the specified limits, i.e. the chips passed the test. Which of the 2 would you expect to fail with just a bit higher or lower temperature than actually tested? Correct, the second one. It is still a sellable product, but you would not ship that one to your quality sensitive prime customer. Second example (so called "Part Average Testing" or PAT): Say, you produced 1000 chips and measured a specific parameter. Again, all those dots up there are well inside the spec limits, so all chips are "good". But it's easy to see, that 998 of the chips group nicely in the same area and just 2 stand out. Which would you expect likelier to fail? Even without any knowledge of what caused those 2 "outliers", they would never be shipped to an automotive customer for any safety critical application (the company I worked for used them for destructive testing to find the cause of the deviation, others just put them in different sales channels). Now take your guess, which category of components will end up in the bazaar like shops in the Shenzhen electronics market? Taking an analogy with 3D printers: Nowadays, you can buy a printer with good QA from upscale brands like Ultimaker, formlabs or Prusa and be fairly sure it works as advertised. Or you buy a "knock-off", built from those Shenzhen warehouse components with no Supply Chain Management and little QA for as little as 10% to 20% of the price. I was surprised to find some extra sensors, switches and even a spare mainboard thrown into the parts bag of kit printers I bought, obviously in expectation of a high component failure rate. Bottom line: Bashing GotWay for quality screw-ups is tempting, but I am rather surprised, how many good wheels they manage to ship out under these conditions. Only very few of us would be willing and able to foot the US$5000+ bill for an ACM built to automotive quality standards. While rightfully demanding QA improvements and honoring the efforts of responsible distributors for the good cause, we need to stay aware of the fact, that we are all potential crash test dummies riding prototype devices to some extent.

    My whole body is starting to stiffen up as I type this Unfortunately there's no video. I was cruising with my Monster to some good tunes on a very nice curvy sidewalk. Probably 15mph max - the tunes were definitely pumping up my speed There was an outside curve that had hedges pruned right up to the edge of the sidewalk. You know where this is going right Just as I was thinking my speed was a tiny bit too fast for the curve and the bushes seemed like they might juuuuust brush my feet - Bam! The left pedal caught, the wheel stopped, and I flew off the right side, twisting as I caught some air. Landed on my right and slid on the adjacent dirt/grass very hard. Kind of knocked the breath out of me and for a couple of seconds I thought that this might be the fall where I break something (something personal, like a bone). I lay there for 15 seconds and then slowly started moving, not wanting to injure something worse in case I was broken. After about 5 minutes of very slow movements I was able to climb back on the Monster (which seemed to be unscathed) and limp home. My right hip, groin, ribs, arm, and shoulder feel like they participated in a Monday Night football game, without my permission. The one positive take away is the reaffirmation to wear full protection when I'm going to be out riding fast. In this case I was wearing a long sleeve shirt, gloves, elbow and knee pads, and my helmet (which I wear even when I'm not going fast). Tomorrow is not going to be fun

    Just a short video of trying out some new trick filming ideas/techniques including: Using a motorised slider rail (horizontal & vertical). This works really well for filming tricks as the movement of the camera is more pleasing to watch than static "CCTV" footage. Filmed during a lunchtime session, the building in the background is the Shard. 3 meter selfie pole - when spinning around fast it generates loads of wind resistance and makes a crazy noise. I have also been trying some tricks in my Tron costume - I got buzzed by the met police helicopter last night which diverted its flight path to have a look :-)

    My new Gotway Luffy received a facelift today! Since Luffy will soon be headed to a pediatric rehab center for study I figured she will be tossed around a great deal and suffer from irreparable trauma so my staff and I fabricated a plastic protective outer shell. First Luffy was encased in plaster using bandages that are traditionally used for stabilizing fractures. Once the plaster bandages hardened they formed a replica of Luffy's shell.. The plaster shell was then carefully removed from Luffy. This required using a cast saw and then slowing spreading the plaster bandage to dislodge Luffy. The plaster shell, called a negative mold, was then poured will plaster of Paris and a pipe mandrel was inserted in the center of the mold. The mandrel allows for the mold to be placed into a vise for modifications and also provides a conduit for our vacuum system to extract air (discussed later). Once the pored plaster hardened the negative mold was removed exposing the positive mold. The positive mold has tiny flaws which need to be smoothed and filled. Once this modification is complete a cotton stockenette membrane is placed over the positive mold. This allows for adequate vacuum pressure and even atmospheric compression during the plastic draping process. We used 3/32" copolymer plastic for my protective shell. It has flexible properties but is rigid enough to handle bump and spills. The copolymer sheet was heated in a large infrared oven to 350 degrees. Once the plastic sheet was at the proper temperature it was removed from the oven on a caster type table and then the colorful transfer paper was applied over the plastic.The paper has specialized inks that literally transfer into the hot plastic. In my pediatric practice we have over 50 colorful patterns kids can select from for their orthopedic braces. The table holding plastic sheet was then rolled over to the positive mold and with the assistance of 2 of my staff the plastic was carefully lifted and draped over the mold. A vacuum pump was then turned on and the plastic was completely sealed around the molded so there were no air leaks. The vacuum pump then withdrew any remaining air inside the mold allowing the atmospheric pressure to gently form the plastic around the mold. Once the plastic cooled it was cut from the mold and taken to the shop area where it was further trimmed and ground smooth. Once the shell was complete velcro straps and padding were added. There are much easier methods to protect your wheel from abuse but this was a fun project and should make the kids at the rehab center very happy!

    Look what the mailman brought us today. A brand new KS14S from KingSong, where the S stands for Sport. This is the latest Electric Unicycle from KingSong and I’m pretty excited as one of the first to review this unit. Let me know what you think about KS14S?

    Hi guys, I wanted to share this recent adventure, and give you some advices so that the same thing won't happen to you... So I was riding alone, getting some fresh air as I always do during hot evenings, I had my gotway MCM4 that tops at 22km/h (this is important for after). After riding for about an hour in the forest, the dark was here, at about 10pm. I was heading back home on a bike lane, passing next to an inhabited complex for moderate revenues, when out of nowhere 6 youngsters came out and started yelling at me (can't remember exactly what), then started chasing me. I accelerated as fast as I could. I didn't even hear the final alarm but it must have been very brutal, because the EUC had no more power to keep me balanced and I fell off it, luckily I was able to run, the EUC rolled into a bush, and the 6 guys catched up with me. One of them threatened me with a knife, another had a cutter, they asked for my cellphone and money, I gave them what I had on me, but couldn't find my cellphone. The 6 guys where taller than me, and even though I had an electric shocker, I didn't use it because I was too afraid to get stabbed. They left very quickly, luckily they didn't take my EUC, after a while I headed back home, my legs where shaking from the stress, I have already had some agressions on my EUC but they never succeded until now. I filled up a complaint today at the police station, but without a good description (I wasn't able to remember the faces of my agressors because it was dark and I was under stress) they told me there almost no hope to find them. From now on, I won't go out at night with a slow and weak EUC, I think that if I had my ACM for example I would have gone away, I need to avoid some areas but I couldn't guess it would happen in this particular one, so I'll look out for groups of people. I highly recommend to ANYONE to be aware (in France at least) of these things happening. I'm glad they didn't take my EUC, I guess they thought it was broken..and it didn't sustain any major damage, I had some padding around it.

    About a year and a half ago I purchased an inspire from DJI which is the biggest drone manufacturer in the world so I decided to join the forum because the inspire is not a beginner drone, shortly after joining I noticed that people on there are mean, nasty and very very rude, it seems like you had to be an advance pilot to join the forum because the beginners got treated like S.H.I.T. Including me. Guys on there actually started threatening each other. It was not a good experience to visit at all. This forum is the total opposite you guys are very very nice and very helpful no matter how simple or dumb the question may be, I feel very comfortable asking anything on this forum, some guys even go above and beyond to help others make a purchase decision and always give their honest opinion, it's a joy to visit this forum and I have to admit some of you guys are pretty funny ?. In closing I just wanna say keep it up guys, really appreciate it ??

    You do owe them a conversation if you want to do your bit for EUC community relations. If the public see early adopters of this 'new' technology as being aloof, inconsiderate, or even outright rude, then it is so much easier for them to hate us, and it gives them ammunition they can later deploy at council meetings and the like... I am not even slightly a 'social' person, but I will always stop to talk to someone taking an interest in my wheels, and I do my very best to make them leave the conversation feeling like they've had a very polite and courteous (and in my case tediously technically information-rich) exchange with someone doing a new and exciting thing, and not only that, but doing it well, and with maximum consideration for pedestrians. I want people to think about me, and us, like that. Having been doing that for several years now, I have a whole town full of people that know me and my wheel, and wave and smile as I go past. All from a little bit of basic politeness... Of all the people I have ever stopped and talked to about EUCs over the years the feedback has been overwhelmingly positive, and those people leave that conversation very much on my side, and certainly not seeking to prevent me doing it more. This is especially important in places where the legality of the EUC is still questionable - we need the people on our side (or at least not actively against us) if this is ever going to be mainstream and legal like it should be...

    Hi, everyone, Rockwheel has been created for the fifth year, and it is honored that it has not yet closed, after all it is not a profitable industry, in 2012 I had the first Solowheel wheelbarrow after the start of 2013, I gave up The original business, all devoted to the start of the operation of Rockwheel, because I love, my first wheelbarrow is gear motor drive, because I like it to accelerate the sound of metal roar, so I named Rockwheel. Natural air-cooled system, we tested 30 minutes of continuous climbing, the controller temperature of 58 degrees Celsius,

    As a fervent fan of your products I implore you to consider adding one or more of these improvements to your future wheels: Replace the single tone beeper with a proper speaker and vary the loudness of the beeps based on the speed of the wheel. When we ride your wheels fast (like your wheels are meant to be ridden) we often cannot hear the warning beeps because of the wind noise in our ears. Provide a means to turn off the beeper. Sometimes we can ride very far on a low battery and we are forced to hear the constant beeping even though we are traveling at 5 mph. This annoys us and it annoys the people that we ride by. Provide additional hardness settings. Some people think your Sport mode is still too soft. Why not please everyone? Replace the single brightness LED with a multi-level LED, just like the cheap pocket flashlights that everyone owns. The brightest level should be much brighter than your current LED lights, which are just about useless for riding at night. And please keep the flash mode, it's a great safety feature for daylight riding. Provide a battery indicator that can be seen by the user when looking down at the wheel. The best EUCs in the world (MSuper, ACM, and Monster) require the user to step off the wheel to see what their battery level is. In a perfect world it would be a multi-digit LED display that would show the battery percentage. Provide a fast charger for your high capacity wheels (e.g., 1300wh and above). We don't like having to wait 10 to 20 hours to charge one of your fantastic wheels Change the design of your wheel shells so that the screws don't snap in half after a bad fall. Your wheels have a great reputation for performance and desirability, but they also have a bad reputation for cheap screws that snap in half too easily. Your competition doesn't have this problem, so show them that you can make the best shells available. Your wheels are so powerful that we love to push them to extremes. Show the world that you can make a shell that is tough and can take the abuse. Many people like the option of wider tires, and have even gone to the extreme of cutting your beautiful shells to accommodate a wider tire. Why not design for wider tires and provide that as an option. Trolley handles are so useful, and you demonstrated how nice they can be with your super popular MSuper V3. Why not make them standard in all of your future wheels. People would love you for it. You may be the first manufacturer to standardize on one size pedal brackets. Now provide a range of pedal options that can be interchanged between all of your wheels. Some of us have small feet and some have large feet. People love having options to pick from. A built-in kick-stand would be extremely useful, and you would leapfrog all of your weak competition forever if you were the first to add one. Add a cutoff switch to the bottom of your handles. It's such a nice feature to have when having to lift a wheel over an obstacle Add bluetooth speakers, but please don't use them yourself to make announcements to the user. When appropriate (Monster, MSuper, etc) add a mudguard. Maybe even a removable one. Surely you've seen the 3D printed mud guards that people have been making themselves for the MSuper? So many people have difficulty with your newer phone apps. Many of us don't like to depend on having an Internet connection to use the app when riding or configuring our wheels. Your wheels are the best for riding in remote areas where sadly there is no Internet. Please keep the ever useful USB port - such a great feature of your wheels Instead of the dozen or more diagnostic beep codes that nobody understands or even knows about, how about providing this diagnostic information to the phone app, or a voice prompt using your new bluetooth speakers. I don't know if you will ever see this letter. I'm your biggest fan and want you to succeed and destroy all of your meager competition. Maybe some of my suggestions can help you stay the number one EUC manufacturer in the world. I'm rooting for you

    Surprise update, May 19th: Gotway now uses stronger wiring for the motor cables going from the motor to the connectors. They have been convinced by a dealer. Not sure how much it has to do with this So the problem is extremely unlikely to appear again and can be considered solved. June 23rd: it is a general problem that the wheels can produce higher currents than the cables can take, so melting is inevitable under the right circumstances. See this thread for a more up-to-date discussion (the exact same happened to this guy and me): -- Final update, April 27th: wheel is working again, Ian/Speedyfeet did a great job (and Gotway wasn't bad either)! A bit more results, top of page 16. Don't be afraid to use ACMs/Gotways on steep hills, just don't overdo it and be aware of the limitations of what you can expect your wheel to do (that applies to all wheels, no matter the manufacturer). -- Update #2, April 5th: this issue was a combination of lack of proper cabling (messy cable management + Gotway forgot to put heat sleeves around the various cables, though it is questionable how much that would have changed) and very high, continuous stress on the wheel, which led to the motor cables melting and shorting each other. So don't worry too much about the ACMs or Gotway wheels' safety, this event was more due to an outlier situation (though it does seem some components are too weak in general, and the improvements Gotway did won't fix that, the motor cables melting could happen again - see @Xima Lhotz's pictures page 15) - at least statistically, Gotway wheels are still good (if you're not doing constant steeper inclines). --> If you are concerned, open your side panel and see if the cabling looks good and has heat sleeves. That's the best you can do. Photos how it should look are at the top of page 15. <-- Just be aware under continuous heavy load conditions, the wheels (any manufacturers really, but KingSong for example would probably be a bit more trustworthy) might cut out on you, without giving you a warning beforehand (which is the scary part). Everything is not finished yet, but Ian is in contact with Gotway and this will be fixed one way or another. So far, good customer service from both. More updates when they arrive. -- Update: this issue is not related to the motor connectors at all. I initially believed it to be the connectors because they are a known issue, and the wheel shut off without any warning (like high temperature warning) and failing connectors would do that. What really happened is the motor cables themselves melted together and shorted. Pictures see page 5. Investigation on further details is ongoing -- Another day (or rather night), another Gotway incident... WARNING to everyone with a Gotway wheel, ACM, msuper V3, monster, does not matter (I think it's ok to post this in General so everybody sees it). -- So I just did a night mountain ride and my 84V 1300Wh Gotway ACM died on me with no warning. What happened: I went up a fairly steep mountain (but not extreme, really, an estimated max 20% [update: in hindsight, 15% is probably closer] incline maybe, but constant). It was mostly a hard dirt path, 80kg rider, 60% battery. I went fairly slow and the wheel semed far from its limits (easy acceleration, no warning beeps,...) After no more than 10 minutes, my ACM went dead mid-ride and I hit the ground (thankfully I wasn't going fast). It simply stopped working, tilted right forward and that was it. On inspection, there was a burnt stuff smell coming from the wheel (you can still smell it). Pushing the power button, the wheel beeps regularly and the 5 back LEDs all flash red. Even when the wheel is off, it is quite hard hard to turn the tire. The light is working normally (you can switch it to on/off/blinking as usual). Looks like this might be the well-known motor wires connector issue, but this time it's an ACM, not an msuper V3. Afaik this is the first reported such incident with an ACM. So be careful, all GW models can be affected (assuming it's no other issue). If you have a GW wheel manufactured before March (roughly), you have a problem. I have not yet opened the wheel for warranty reasons, will have to ask Ian (speedyfeet) what to do first. Quite bummed, I have a dead wheel, scraped knee and my left hand's palm is bruised. This could easily have been worse had I gone faster or been less lucky. What you can learn: if you have a GW wheel, don't ignore or wait on definitely fixing the motor connector issue (I'm pretty sure that's the reason) if you might be affected. @Marty Backe siliconed the connectors preemptively, I'm not sure if that's enough (*hint*). Completely new, safe connections are probably best. I was aware of what might happen but pushed on, and now I have the mess. Bad decision. Do not think "everything will be fine" just because it was until now, there are no warning signs before a cutout. hard gloves/wristguards are your friends. #1 safety clothing! there's literally no reason not to wear knee guards. Like your hands (palm/wrist), your knees are what realistically hits the ground in most crashes. be careful with higher and constant inclines. I did a 1.5 hour mountain night ride before which wasn't constantly this steep, and everything went perfect and it was quite spookily pleasant In hindsight, no idea how close to disaster I've been Also: F**k Gotway. The wheels are really nicely engineered, but the manufacturing sucks. Well, at least they say they fixed the issue (if it's the motor connectors). The best way to carry a 20kg disabled/non-turning wheel is to carry it on your (hunched) back, arms forward and folded around your head, holding the handle behind your neck, like a modern day millstone of (Gotway) shame. Maybe you get the picture It's better than the "like holding a baby" alternative, your arms will die soon. -- I'l sleep on it, possibly burn a GW effigy, and tell you more once I can look at the insides of the ACM. Looking forward to what your interpretation of the events is. Looks like the motor connector issue to me (or maybe it's a new, exciting Gotway quirk?), but I don't know for sure.

    Always remember that right of way is given, not taken. If you're a pedestrian, biker, or EUCer, if you get into a collision with a car, it doesn't matter who is at fault - YOU LOSE. So I follow these rules: Make sure you're highly visible, especially at night. I wear a flashing light band on my helmet, and a solid one across my back. I don't care if people think I look dorky - light me up like a Christmas tree! Always assume that a car doesn't see you. Even if you have the right of way, don't pull in front of a car until you make eye contact with the driver! Be careful on crosswalks. Many drivers will roll over the crosswalk - be sure that the driver sees you. Be careful of cars making right-hand turns - they are looking left. Drivers see what they are looking for. Usually, they are looking for other cars. Sometimes they look for pedestrians and bikes. They NEVER look for EUCs. On a crosswalk, people are traveling slowly - drivers expect that. They look a few feet left and right and think they are clear. They are NOT expecting an EUC flying across at 20mph. It's always better to be careful than to be a hood ornament (or worse).

    Since i did not find the original thread ( imho the posts were just "hidden" in some other thread..?) from the first dynamometer results published at http://electrotransport.ru/ (linked here by @Raptor) here a new thread with some new results: http://electrotransport.ru/ussr/index.php?msg=973382 The full tests including description of the measurements are published at http://airwheel.ru/test-monokoles-na-dinostende/ (also with a comment that the dynamometer is made for motorcycles with much more HP and so the results are not really exact absolute numbers but a nice comparison between the different wheels)! Also i did not see a comment about the "measurement probs" he mentioned in his first test: He could not start the dynamometer with full power from the wheels, because some fuses burnt... So he had to accelerate it "slowly" up to ~10-15km/h before he could apply full thrust. So some/most of the charts show some quite low powers for low speeds. Mabye he found a way to overcome this prob or it is still seen (imho in the charts for the high power 18 inch wheels?) Some interesting first points: - the IPS Zero shows some strange behaviour: The power output halves for speeds about 16 km/h! Also with a max power of 1.1kW it is one of the weakest of the tested models... - bigger batteries (capacity) give more power! ( how to translate "Na no na ned" to english? ) - nicely to be seen in the comparison between the KS16 340Wh and 840Wh model. - The MSuper V3 1600Wh 84V started a new era: it shows a max power of 4.7kW! - a nice statement regarding Airwheel (not included in the summary charts): "Test shatters all hope that this device can drive" -Test of ACM with custom LiFePo4 batteries: ~30% power increase! - Test of Inmotion V8 with Samsung INR18650-30Q 3000mAh cells: ~20% power increase, but the internal fuse was not able to withstand the increased current... It would be great to see the results from @EUC Extreme's custom Gotway in comparison to a standard factory version! A Quick overview of the results (links to the pics of his homepage): 14 inch wheels: 14 inch with more "power": 16 inch wheels: 18 inch wheels:

    What was suppose to be a great Father's Day turned ugly! My neighbor was helping me launch my jet ski into our lake. Everything was going smooth after I backed the trailer down the ramp. I then let him hop in the driver's seat to pull away from the ramp as I began pushing the jet ski into the water. All of the sudden my truck started rolling backwards towards me. I jumped out of the way and ended up between the truck's rear fender and the wooden dock. Dumb move as I was trapped! My truck continued to roll backwards crushing my chest between the dock and the rear fender. Somehow the truck then stopped! I later found out the jet ski trailer had jackknifed 90 degrees and wedged inself into the lake bottom halting the truck! My poor neighbor had his own issues that I was unaware of at the time! He had climbed into the truck panic stricken after it rolled down the ramp and shut the door trying to keep the water from coming in. I later found out he had to swim through the window to escape drowning! Thank God the window was open! Both my neighbor and I are safe but my wife is pissed at me for not going to the emergency room for a chest X-ray. I suppose I should get checked out after looking at the big dent my chest put in the fender but I feel fine. The other dent in the fender is from my hand pressing against the metal attempting to get free! My truck is probably totaled after being submerged for an hour. If that is not bad enough my wife's new KS 14C, my drone and new goggles, camera equipment, iPhone, all EUC chargers.. all gone. This was a bad hit today but it could have been much worse. We are alive! The material items can always be replaced! Here is some footage I shot while I was still in shock talking about my truck.

    @Hunka Hunka Burning Love I've quit until I moved into a new neighborhood, it is now done ! So I ride my EUC again, even though I'm a little nervous now when riding solo, and I got rid of my "slow" EUC, not because I like riding fast, but because I want to be able to escape if needed (28kph is a minimum, because most "normal" humans can't run that fast or not for long). I think that some events can take away the fun of EUC, but it is still an useful way of shifiting around in a city. I only know about one rider who stopped riding EUC, and moved on to electric scooters, he just felt like he couldn't go fast enough with his EUC (a V8), he was scared of fast EUC (in case of a failure) and wanted more power and speed, he is also a motorcycle enthousiast this may have influenced him. I think most people who get to know how to ride an EUC don't quit, even I who had the most trouble riding EUC in my city (that I know of) don't give up

    Day one on the fabrication of the EUC test rig. I will be using the Gotway ACM 1600 for the test runs. The fabrication of the rig should only last 1 week (famous last words). There will be a number of structural elements added to the rig as I proceed. Once complete a 2 channel temperature data logger will be installed with probes place directly next to the 3 motor wire bullet connectors and also the mosfets. In addition to the sensors various ropes will be used to simulate speed bumps. Here is the first test without any structural integrity added.

    Was leisurely riding the bike trails this morning when a cyclist passes by me. I got to use my snappy comeback when he gave me some sass CYCLIST: You're not going to get any exercise on that thing. ME: I go to the gym for exercise. I do this for fun! CYCLIST: ... CYCLIST: Well, uh, go have fun somewhere else! A bit later, I passed him while going up a long incline and said "How's that exercise?" and then zoomed off. Hah!

    I've purchased 4 wheels from Jason at ewheels and I have experienced nothing but outstanding service. He has gone way over and beyond to make me happy as a customer. I hate reading comments trying to tear down his character saying he is just selling Gotways or any wheel for the money. If you read the many posts from him on this forum you will find that he has been an advocate for EUC riders and has pressed companies like Kingsong and Inmotion to make changes for the safety of the riders. Many of the safety characteristics raved about in Kingsongs was from Jason's constant input over the last couple of years. I'm glad to see ewheels selling Gotways now so maybe we can see the benefits of his tireless efforts in improving the QC at this company as well. We all love riding wheels and we all want to be safe of course. Let's keep our focus and efforts on pushing these companies to make the right improvements.

    Linnea tell me I narrowly dodged a bullet [again] , our Wheels where shipped a couple days after the discovery—why this information was not disseminated earlier is a bit troubling. As a result of this, I'm hiring a China agent to forensically exam every shipment coming out from both the KS & GW factories, interviewing Engineers on FW/hardware changes between batches, comparing photos, & obtaining stress testing video evidence. "We changed new program in the batch of your wheels which shipped out on May 16th, 2017. That is we change better program in your wheels. We double check and found that you don't have any wheels which was shipped out within May the 1st, 2017 to May the 15th, 2017."

    I had a Monster Energy drink this morning & so embarked on the ambitious project of completing the 'Choosing the Right Battery Pack' Blog article. Euphoria has since worn off, will adding additional text tomorrow... https://www.ewheels.com/choosing-an-electric-unicycle-with-the-right-battery-pack-for-you/ There are now dozens of different battery cells being made by the big manufacturers LG, Samsung, Panasonic, & Sony. For use in an application like an Electric Unicycle, the two qualities that make a particular cell more suitable over another are it's power output (Amps) & energy density (Ah). Until fairly recently there was an inevitable trade-off between either high-powered cells (e.g. Sony VC3/A123) and energy dense cells—there's the example of the Panasonic NCR18650B, which had capacity, but could only deliver 2-3 sustained Amps. What has been one of the key drivers in powering the Personal Electric Vehicle revolution, is the introduction of >3Ah (>10Wh) batteries which can ALSO capable of sustaining high currents above 10 Amps. The Battery cells which are most commonly found in Electric Unicycles are shown above. Although lacking in capacity & somewhat outdated, the Samsung 22Ps are still quite common for many Self-Balancing devices because the cost per cell is very low. Ideally, a smaller battery pack (<32 cells) would have more powerful cells, like the HG2 (found in our small 12" IPS a130s) or the VC3 (used in the Solowheel) to provide the necessary sustained power even, if the speeds are modest. Because the cells are nearly all capable of the same 10A power output, the calculation then becomes one of how many battery cells you need for your requirements of speed & Rider weight—hill climbing expectations are also important factor for power, but to keep it simple, it's has not been shown here. These figures are probably on the conservative side, but for a device where getting enough power is the vital for survival, erring on the side caution is preferable. This next illustration shows how the battery cells are configured, their capacity & power outputs in several popular Electric Unicycles. There are two defacto standardized voltages for most Wheels: 67.2v, which is comprised of 16 cells in a series & 84.2v, with 20 cells in series. Good arguments exist for both voltages, but for higher performance Wheels, the increasing trend is converging towards the higher 84.2 voltage. This is mainly on account that motors of higher voltages are capable of higher speeds with better brown-out safety margins.

    So, I bought my EUC a few months ago and, besides trying it a few times after it was delivered, I kept putting it off on account of the weather. (In hindsight, that was a mistake as I had unlearned everything I had learned back then.) These past few weeks have been fantastic, weather-wise, here in the Seattle area. So, I decided it was time to try to start learning again - in earnest this time. My legs are sore, my back is sore, and while I managed to avoid any falls, I did twist an ankle. Yet, for the first time this morning, I managed to start from a standstill. No walls, no rails. Just me and my apparently awful sense of balance. Better, I repeated it several times in a row and I am happy to say that I can get on my EUC on my own, unassisted, and actually travel more than a few feet. I already know I can actually travel on it, I just have to master the transition from jumping on it to traveling forward. I'm still wobbly and I've still got a long way to go. But, I can finally see how it can be done. It's gone from seemingly impossible to "maybe." I'm pretty happy with maybe.

    I would say at least 75 percent of our sales will be online. We there are 3 of us at the moment. There is a market locally, and maybe a surprising one. To cover cost of the store and salaries we would need considerable sales, with that being said this is not expected to be profitable for a long time, if ever. I really love EUC's and I feel like I can contribute a lot via this store/brand. I don't run the store myself full time, so this isn't my only project and it will likely be supported by other endeavors for a long time. It is kind of crazy, and it doesn't make a ton of sense, but I imagine the dedication could pay off in the long run. Either that or we get a ton of people into the hobby even if the store isn't a financial success. If I can get people into this, achieve better legal status in my area and even beyond my own, and help build the community this will be a success to me. Eelectric unicycles really did change my life in an awesome way and I know it can do the same for a lot of people.

    I sent Lewis a V8 to try out, (he has 7.1m Subscribers!) gets a decent airing, especially at the end....

    Last night I had a rant at another member, openly in a thread. It was wrong and I should not have done it. what I should have done was addressed my issue with the member via private message. don't go looking for it, I deleted it ( hid it) because no one else needed to read it who hadn't already done so. i have since contacted that member respectfully, via pm. i apologise to any member who was offended by the language, or content. and I apologise to the member here publicly, for potentially embarrassing him, although, I actually think he cannot be embarrassed, and that was a complement. ( name withheld, because not doing so would be a second form of public "calling out" which is not appropriate either.) next time I get hot under the collar, I'll wait a full hour before pushing "send". I'm sure that will prevent any further silliness on my part.

    Having driven both (own the V8, multi-hour test drive on @logos122's MSuper3S+), no. Main difference is really the driving feel of the 2 companies, size / weight regardless. InMotion is the hardest EUC response, while Gotway is way more soft / wavy / washy, hence slower and softer braking. Only other thing is, as you enter into 18" EUCs, turning is more active and above the hips, not just simple and passive angling between the legs. Less fun? No, different fun! MSuper3 or any 18" is not really the optimal size to do tricks in a specific area, although you totally can. 2" differences between 14/16/18 are all relative, but, obviously, tricking in one space is best on the smallest 14", then 16", etc. As you seem to be satisfied with your V8 purchase, for your oldest here, I would really recommend the V5F+ from eWheels (not any other variant; ~27lbs, 3lbs lighter than the V8 & waaay lighter than the MSuper3). That is, if you can stomach the 15-16MPH top speed. Honestly, the more I ride both V5F+ & V8, except for top speed obviously, I really think the V5 line is a step better than the V8 in terms of all around, well-thought out design and ride quality. Though both carry the InMotion DNA, more development was put into the V5 line, and it shows. I've driven everything in my sig plus the MSuper3S+ (except for my Monster which is en route!), and I would argue the V5 is the best EUC I've ever owned (obviously throwing out the needs of super-fast and super-long-range). note: all Gotway EUCs have a loud, non-cancellable 3rd alarm speed warning that cannot be turned down in volume, something to keep in mind going around a college campus. note: although I love 18" and above EUC's, there is, visually, a natural prejudice amongst pedestrians towards you. When I'm riding my KS18A down NYC streets, ppl jump out of the way as if I'm riding a big-a** motorcycle, as opposed to when I'm on my V5, people tend to treat me more like I'm on a toy (go figure). ========= The MSuper3 series is really all about going fast speeds with long-range comfort. If these are not your top priorities, carrying a 40+ lb EUC up stairs can be cumbersome. Really can't go wrong with any of the named EUCs though, all excellent choices, just more specified for certain uses than others.

    Heyho... Finally some words and Pictures about my new KS18S... Let's start with some Pictures: The wheel: Some ingredients: and: Give this Outcome in the end (Really dont like the KS Advertising :-) ) Open Trolley: Mud Guard: Some words to the wheel: (Some Points i "lend" from another KS18S owner, as i am lazy and can't invent the wheel new) Plus: - Extreme "hard" driving mode, even the softest mode is stronger than my GW V3 67V - Seat is included and can be used on Long rides - Powerful, visible and reversible front and rear LEDs - This is the most powerful wheel produced by KingSong to date, both in torque and Speed. - fat Tire of 2.5 , extremly Grippy, Kenda Manufactered - Built-in fan to avoid overheating (starts at 54° Celsius and stops when brought down to 40-42, don't nail me on exact numbers) works flawless - Old Shell delivers really great stability while driving as it is leaning to the knees(once u are used to it) - 4 speakers, they seam a bit dump first, but on driving Sound excellent! - Excellent Build Quality with Focus on safety -fat wires, mosfets, axle etc (see later photos) Minus: - No trolley: But i have done somethin against that - No mudguard: But i am experienced in building one :-) - Old shell, its very "high", thats very different driving style from the other wheels of the market thus requiring a time of adaptation ? Can also be seen as positive But at all i am not good in listing, i better find my own words: This wheel is a powerHorse!!! The pedal Feeling is rock hard, on accelerating and braking there are nearly no movements of the pedal. This goes so far that when i step back on my Gotway V3 67V that on this wheel i am afraid of the pedal "sacking" for some moments, as you get used to this rock hard pedal Setting on the 18S so fast. Also The 18S main difference from my old 18A is that it is really, really agile and reactive. Where my 18A was sluggish and hard to idle, because slow in direction changing, the 18S really rocks...This has an disadvantage also: When you Need to carry the wheel a bit longer, over some stages or a barrier, you definitly have to Switch the power Off, because if you lift it up and dont have it perfectly grabed in the middle, the wheel/tyre starts rotating so fast and flippy, that you can not calm it down by moving into the other direction anymore. It reacts that fast...and accelerates like a rocket. As this question will certainly follow: Yes, it eats up my Gotway V3(67 Volt 1160wh) to breakfast....Easy! It is way harder and faster, way more powerfull. So this seams the only left competitor against the GW 84V rockets, but i cant compare it fairly to that...as i only have some minutes on a v3s+ until now. Hope on a Meeting we can do some comparison between the V3s+ and the 18S in drive behaviour. But i have to say that i doubt that the 18S can cope with the 84V, as it's just 25% more Voltage.... Where it stays out is the build Quality...and the attemps of KingSong to make their wheels safer, here some photos of the inside with some Explanation: I have open it up and all the wiring is top notch and on really thick wires. KS brings their Motor wires through one axle and the sensor wires through the other axle. The Motor wires...i found no AWG on the cable, but a print saying 2,5mm .....so each of the Motor cables is 2.5mm and it is only one hard strand (not multiple strand wire)....i guess on this there is no Need to fear heat anymore! Under the green protection are the 3 Motor wires...as you see all wires nicely hold together: Try to shoot the print on the Motor wires(3 black cables)...These wires are each just "one strand": The batteries are paralled and all go into one Connection Board with PCB, where each Batterie pack is secured by a fuse, so if one goes crazy or dead, your other batteries work on! Here you can see the PCB-thingie(it is under black folie)...the PCB inside has 3 x 40Amp Fuse, one for each Batterie: The axle has getting thicker than on older KS: End of Part 1 :-)

    We started a local store in Siloam Springs, Arkansas. OneSeven Electric Unicycles. It has been a blast, as well as a ton of work. Traffic has been good and a couple members have purchased our wheels online already, but what I really want is for a member of the forum to visit our physical store! I also want to offer a special for that person. $300 off ANY wheel, plus some OneSeven merch. Whether you want to spend $199 or $2199 we have something for you! First timers welcome, one of our employees would be happy to help your learn on your new wheel. We also have a giveaway running for a new Gotway MCM4, it is the pinned post on our Facebook page! You can also enter at OneSeven.xyz if you join our mail list (Site is still a WIP) OneSeven 321 W Tulsa St Siloam Springs, AR

    Dear all GotWay users, We got some feedback from riders that their Msuper 3s+ and ACMs+ has cut off problem when jupm kerbs or speed up suddently. With these few days efforts to gathering motor code and do more testing with different program, we found out such problem happened in the wheels which were shipped out from our factory from May 1st, 2017 to May 15th, 2017. But most parts of this batch of wheels are sold in China mainland, and the second majority part to another distributor not in China market, but he still not sold out any wheel of this batch as the wheels are still in the jouney of sea freight. We have arranging ship out new mainboard to him to replaced the old mainboard when his stocks arrive. In this batch of wheels, we set lower limited current in program to avoid riders suffer cut off during high speed riding. Before we ship out wheels, we did tests of the mainboard, and till now we still not get any feedback about this problem in China mainland even most of these wheels were sold in China. Anyhow, we have contacted distributors who has wheels within this batch to ship them new mainboard to replace the old ones. Wheels that has problem in cut off in high speed is normal problem. Electric unicycles has limited speed, once reach the limited speed, it will cut off as the current burn mosfets. Some wheels vibration after fail down, it is because wheels deformed after fail down. Vibration became more obviously when ride it in high speed. Please contact distributors to change tires to solve this problem. Here would like to note all GotWay riders who like ride fast speed to wear protection clothes and helmet to avoid any unexpected cut off. Wish all of you would have nice riding experience with GotWay! Thanks for all GotWay riders that support us all the time! Best Regards, Linnea
