    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

    I'm going to go out on a limb & say I think KS need to rethink their developmental priorities. If the goal is to break the land speed record riding through a shopping center on one Wheel, great, but if they want a successful long-term business, then I think they should be focusing App development, improving waterproofing, serviceability & reliability. I don't believe there is the remotest chance of any regulatory body approving a >40kph Wheel.

    I'm a 79 year old professor, about to acquire a second-hand E+. 60 years ago I rode a unicycle (pedal-powered), and hope some of those ancient skills will enable me to adapt to this new device. I need some sort of portable personal transporter because my knees don't support walking (osteoarthritis hates impact), though I'm otherwise quite fit. My goal is to efficiently traverse the very large campus on which I still teach. A few questions of the resident gurus... Price with training wheels is about $300 - does that make sense? Is the E+ UL-2272? Campus requires it! When I inspect the unit, what should I look for regarding functionality/safety? Remember, I won't be able to ride/test it until I adapt/learn, which will take some time. Is there a way to estimate the condition of the batteries? Is it powered by a simple array of replaceable 18650 cells? Do the training wheels accelerate the learning process, or improve safety? I have a helmet - do I also need bodybubblewrap or ??? Will initial training be enhanced by a shopping cart? If I fail to adapt, will I have a problem finding a buyer in that price range? I'll be grateful for comments/suggestions, other than "Don't do it, you idiot!" Thanks, gurus.

    The unexpected upside of getting an EUC for your son; he's now asking if he can take the dog for a walk, even when it's raining!

    Today was a really nice day here in Maryland so I went out for my first long ride of the year (about 18 miles). On the way through downtown Columbia I have to cross a really wide intersection that has 6 lanes of traffic. I was at the lower left where the orange cones are (they've finished work now) and as soon as the crosswalk sign was on I started out across the intersection. I got across to the middle island with no problem but there was a lot of traffic headed towards me and turning right (in the lane that heads directly into the camera). Now, since I'm in the crosswalk I have the right of way so I am moving ahead slowly waiting to get the attention of a driver so they will actually give me the right of way so I can get to the other side. This one guy in a massive SUV stops so I start moving ahead, then he starts going again! Then he seems to actually see me and stops again. The woman behind him doesn't expect him to stop (certainly couldn't see around his massive SUV to see me) and whacks him in the bumper. Since I was a witness to the accident I make it across the street and stop to be sure everyone is okay and give my name if needed. The guy in the SUV hops out and accuses me of causing the accident! I explain to him that I was in the crosswalk and had the signal, and he says well he had a green light and I "came out of nowhere" so it was my fault. Then some third guy comes out of his car and says "that's a motor vehicle, you shouldn't have been in the crosswalk!" I try to explain to him that although it has a motor, it's not classified as a motor vehicle in Maryland. You can guess how well that went. Fortunately, there were a bunch of cops about half a block away because it's near Merriwether Post Pavilion and a concert was starting soon. So I suggested that the third witness in the car go get one of the cops. In a couple of minutes the cop was there and he asks Mr Angry SUV Man to give his story. It was pretty funny. The cop asks, "Was he in the crosswalk?" Mr Angry says "Yes." "Did he have the signal?" Mr Angry says "I don't know." I point out that as we speak you can see that the crosswalk signal is green when the traffic light is green. The cop says to Mr Angry, "Well you need to let pedestrians cross." Here's the part that really made me happy. Mr Angry says, "He shouldn't be riding a motor vehicle on the sidewalk!" The cop says, "No, it's a pedestrian device, he can ride it on the sidewalk." (That's the term they use for an EUC or Segway here in Maryland, "pedestrian device".) Mr Angry asks, "Doesn't he have to walk it across the intersection?" The cop says, "No, he doesn't have to dismount, he only has to do that if it's a bike." So I head on my way while the cop gets the two people in their cars to exchange insurance information. After that, I'm really starting to wonder whether I should ever stop in cases like that. And also I need to get a new camera, my old one only has about 45 minutes of battery time so it would have not been running if I had tried to record the whole trip anyway.

    I purchased this wheel from @Jason McNeil about 3 months ago for my sons birthday, but had to wait until (1) his actual bday (4/28) and (2) the most important part, he was supposed to save half the money . Anyway, it all came together today and go figure, it took him about 20 mins to be up and rolling, seriously not fair!

    Hey dudes, I slept the pain away all day and am feeling a little better. Heres some road rash I got through my jeans. The worst pain is in my right ribcage, it got squished but didn't break. I felt it squeeze down though. I was wearing a helmet only, but thankful that I was. It could have been much worse, I am surprised it isn't more serious. I got the wind knocked out of me, it was a hard slam. Wrist guards are a good idea. It was pretty scarey. It's just so fast when it happens. You can't really do anything. This was my own fault, for sure. I usually need to learn stuff the hard way

    We've had several cases of attempts to update the firmware from v1.23 (perfect satisfactory & functional) to v1.25 (more problems than fixes) with the board becoming completely unresponsive. Only solution has been to swap out the board. There's now an enough cases to warrant STRONGLY recommending owners to NOT ATTEMPT TO UPDATE to v1.25 on the 1200W KS. Have asked my rep is this is a known problem, but has not been able to confirm—since Tina left getting answers to even the most simple technical question is practically impossible.

    14c at max speed. Thought maybe there's a little more speed past them beeps. There is not. There is only concrete. Now i I stay home. That shit hurts like a mother. Thoughts: There is no running out a 20 mph failure wear helmet or die, I think I would've been fucked without mine, my noggin skipped across the ground two or three times as I rolled down the street. Roll. Rolling saved me

    Notaguru - Go for it, but be careful I'm 63 and like you I rode a regular unicycle when I was a teenager. And like you I wondered if that experience, even though it was long ago, would make learning to ride my Ninebot One E easier, and I have to say I think it has. I was very cautious in the beginning and rode back and forth in a hallway for 5-10 minutes a day for maybe 2 weeks, but after the first couple days I didn't seem to be getting any better. I read somewhere that people recommended learning on grass (to minimize the damage when you fall). I took it out in the back yard and immediately rode the length of the yard with no problem. Wow! I was surprised. After just a couple round trips in the yard I went out on the street (dead end, no traffic) and rode a good half mile on my first "road trip". So in total I probably spent an hour or hour and a half learning to balance before my first street ride and looking back I think I could have done it sooner. I've now put about 250 miles on my Ninebot and have fallen off twice but no injuries, because I don't usually ride fast and both times I "stepped off" and let the wheel crash by itself. Once was on grass after a rain and the wheel fell into a soft spot. Another time my shoulder hit one of the posts holding up an awning at the elementary school across the street (I was using the row of 9 or 10 posts for slalom practice!). I now try to ride 5 or 6 miles at a time through my neighborhood when the weather is nice, which right now is almost every day. Like some others have mentioned, I had trouble learning to get on the darned thing, and that's also the only time I've received any injuries. I always put my right foot on first and jump up with the left, and sometimes my left toe would catch the pedal on the way up and tip the wheel over, and my ankle would scrap against the edge of the pedal. Ouch! I have found that wearing high-top tennis shoes has helped prevent those kinds of injuries and I also like the ankle support they provide.

    I, like you, have knee problems. I have torn Meniscus in both knees. If I ride distances, I need to wear knee braces or it actually makes my knees hurt worse. I, also like you, rode a pedal unicycle when I was 13 years old but have not been on one since. I took my first EUC to Sam's Club and held onto a shopping cart rack in the parking lot after they closed and rode around it one time. By the time I got back to the beginning, I had it and took off. I rode about 600 ft that night. The next day I took to a local bike path of about 5 miles in length. I rode the whole distance without stopping one time because I did not know how to stop!!! OOPS! I took the whole ride back practicing starting and stopping because I quickly realized it was super important around people and eventually cars. After 3 days of riding my generic wheel, I went and bought a NineBot E+ and LOVED it! It's a very capable wheel. Your price is very good! I've now moved up to a GotWay MSuper and love it even more. Others have answered the other questions well, so I'll avoid those. But I will say that I also own a NineBot Mini Pro, and I think it is MUCH better suited for what you want to do. The amount of control on the Mini Pro is a lot easier to use. You can stop and start without fear of falling off, and around walking traffic, it's a breeze. The Mini Pro is NOTHING like the Hover Boards, and I've owned a few of those too, so I know. The Mini Pro traverses obstacles very well. It can go up and down wheel chair ramps easily, across grass and gravel, and even go over bumps quite well, something the hoverboards can NOT do well. I've even taken my Mini Pro off road and it does well there too since it has a computer that helps keep it straight and level when riding over bumps and angles. The NineBot E+ is also able to do all these things, but it has a much larger learning curve and even when you are very good, you still fall off occasionally. Running around foot traffic on the NineBot E+ is very possible, but not until you are comfortable riding 1 mph or less, and that can take some time. The other thing is that a Campus is likely to be more willing to allow you to cruise around on the Mini Pro over the E+. Especially while you are learning. While learning, many people have quite a few falls and mishaps, and it is perceived as being more dangerous because it simply looks that way. The Mini Pro is super easy to learn, 5 mins tops, and it's SUPER stable. Good luck in whatever you get. Either way, I hope you take up EUC also. It is probably better suited for off campus riding though, which you will LOVE!!! Off Campus, it runs circles around the Mini Pro. On the Mini Pro, I've gone 15 miles on a charge at around 10-12 mph, so it's still capable, but the E+ can do it so much easier when you know how to ride it.

    Saving Marty and the Monster (part 2) So. After getting lost i almost started to believe that i myself might not make it out of the mountains in time, so i started praying. And it went a little like this.. "Jesus take the wheel".. " God please put me on the right track and help me get out of here. Please God i really dont want to spend the night camping with the bears. etc..." Sure enough.. my prayers got heard and after some time of carrying my 45lbs acm up the hills i finally saw a downhill route that looked like it was going in the right direction. So i hopped back on my dying wheel and started zooming dawn the hill. I knew that i had to get down quickly because i needed to get to the park rangers asap so the'll have enough daylight to go out and find Marty. After maybe an hour and a half of riding i finally came across the stupid dam that we were looking for the whole time! At this point my phone slowly started working again. I checked the maps and the park rangers station was not far away so i got back on the wheel and continued down the road until i got to the main gate where the rangers were supposed to be. Walked up to the door but unfortunately there was no one there. So i called 911. My call got transferred 3 times before someone in the right jurisdiction was able to send out some help. They asked me where i was and told me to stay there till the cops arrive. So i stayed put. Shortly after a whole gang of police cars and fire trucks and ambulances arrived at the gate. I made the 911 call at 5:45. From 6-9 i was with the cops explaining the situation, and answering all sorts of questions. Luckily i had a took a picture of Marty and Jeff from earlier that day so i gave that to the cops for description of our missing peeps. I had took a few more picture of the trail names and numbers on my way down. Those, along with a picture of Martys gps coordinates of his last known position gave the rescue team an idea of where he might be. The gps coordinates Marty had pulled up on his tracker turned out to be the nearest cellphone tower which was no good. So i had to somehow describe where my missing guy was to 6 different groups of teams (including; the police department, the fire fighers, the park rangers, the helicopter operator). They couldnt belive that we had made it all the way up the mountain and back down almost to the 2 frewway on "that thing!?!?" Anyways making the already long story short, being the "informant" i stayed with the rescue team leader answering more question and confirming new information they were getting until they tracked down our missing man. By the way the parking lot was 20 miles away from the point that i came down to on my wheel. Had a friend come pick me up and take me back to my car. End of the say i had probably done 50miles of mountain riding on my awesome ACM2.5 which saved mine and Martys life. 🙌🏼

    They've got a newish site on: www.kingsong.com (a bit of a joke, but the hosting is under my GD account ) Even the best Chinese companies are pretty hopeless at maintaining content—perhaps they don't see the correlation between sales & effort invested. My personal view is that they're missing the boat with the defacto 84v voltages now used by Inmotion/GW. You can throw as big motor as you want in any new 18" Wheel, but if the voltage falls below the critical required threshold for the speed/RPM, it's not going to be a good performer. Can't believe how pathetic it is that their App Developer still hasn't added the Location permission (almost a year now!) to the .Apk install package! I've written, pleaded, begged, tried to get other Distributors to make fuss about it, now beyond caring stage...

    So i had to leave Marty behind to go get some help because after 20 miles of climbing a steep hill on the monster and then going downhill another few miles on a fucked up trail with landslides and trees blocking the way he was too exhausted to get back out of there on his own. This is where my mission began. With %20 battery left i turned back and started heading back up (for about 2-3 miles) to the top where i thought i would have cellphone reception. Somehow i missed the spot and/or my cell didnt pick up the signal so i kept going up hoping that i will soon get a signal. At this point my wheel was beeping at me pretty hard and i was barely moving. Came across two Y crossing. Both times made the wrong turn.. went down for about 10 min, realized that im not heading the right way( looking at a very blurry google maps image i had loaded on my phone) then pushing my wheel back up the hill on foot. So after being lost for over an hour with no map, almost no battery, no water and no cell reception i was starting to think im stuck on this damn mountain for good. To be continued. Stay tuned for part two of operation save Marty and the Monster

    Your story telling makes me laugh Ando Yes, since I'm tying this, I did make it out, found by a Helicopter and Search & Rescue. 16 hours after leaving home, I got back. I'll post a 'story' tomorrow (Sunday) that explains the madness that happened to me. Jeff has a good story to tell too, and your's sounds great too. I can't wait to hear the full story of what happened to you. This was an EUC ride for the ages that fortunately now we'll all be able to laugh about in the future. I'm never taking my damn Monster on mountain trails like that again. And please, nobody tell me again how a Monster can climb nearly as good as the ACM - give me a break

    Just thinking out loud, but wheel wobble in EUC’s can be explained in the same way that we think of bicycle instability. In my metaphor, mechanical trail (normal trail) is the perpendicular distance between the projection of the CoG onto the ground and the point of contact between the front wheel and the ground. This latter point is actually a patch (a small ellipse) whose size varies with the inflation pressure of the tire. Trail in bicycles or motorcycles is always designed into the geometry behind the contact patch (in the direction of motion) because when it is forward of the patch, the bike is highly unstable. EUCs don’t have a fixed steering geometry like bicycles, and therefore mechanical trail effects are entirely determined by the projection of the CoG on the ground (forward or back of the contact patch). Mechanical trail is one of the most important variables in determining the handling characteristics of motorcycles, bicycles and (in my estimation) EUCs. In bicycles and motorcycles, larger trails force the bikes in into stable, straight-line motion, because the rear wheel drags the rear part of the front wheel along the axis defined by the front and rear contact patches. For that reason, larger trails are favored by inexperienced riders because they are more “stable” (at least in a straight line). Think Harley-D. In theory, stability increases as the computed deviation from the ideal path during steering action is reduced, and thus a trail of zero is ideal because it eliminates: 1. influence of the position of the center of pressure of wind forces coming from the side, and 2. wheel flop effect. What I think riders on this forum are experiencing as “wobble” is wheel flop by another name – a steering behavior in which a bicycle or EUC tends to turn more than expected due to the front wheel "flopping" over with any steering input right or left. Wheel flop is caused by the lowering of the front or back end of a EUC as the pegs are rotated away from the "straight ahead" position. In wheel flop, the force due to gravity will tend to cause rotation to continue with increasing rotational velocity and without additional rider input on the pegs. Once the pegs are turned, the rider needs to apply torque to the handlebars to bring them back to the straight-ahead position and bring the front end back up to the original height. The rotational inertia of the wheel will lessen the severity of the wheel flop effect because it results in opposing torque being required to initiate or accelerate changing the direction of the wheel. Increasing wheel flop increases the torque required to bring the EUC back to the straight-ahead position and increase the EUCs tendency to veer suddenly off the line of a curve. Also, increasing the weight borne by the front wheel of the EUC, either by increasing the mass of the EUC, rider and cargo or by changing the weight ratio to shift the center of mass forward, will increase the severity of the wheel flop effect. Increasing the rotational inertia of the front wheel by increasing the speed of the EUC and the rotational speed of the wheel will tend to counter the wheel flop effect. I suspect, more fundamentally, the contrasts we see in EUC performance between say a Gotway Monster (22” diameter & 70 lbs) and a Gotway Luffy (10” diameter & 16 lbs) are basically the result wheel flop. A certain amount of wheel flop would generally be desirable, but an EUC with too little wheel flop would be sluggish in its reactions to turning inputs on the pegs; one with too much wheel flop would tend to veer off its line at low and moderate speeds.

    If you get a new shaft, the exchange is basically pretty easy. The only awkward thing is getting the old out, and the new one in place. It requires a crush. It seems that Gotway is not willing to provide a mere shaft. So the only option is to do that somewhere. But. If the shaft has torn from the beginning of the thread, it can be corrected by another means. And it's better than the original attachment. No nuts are needed at all. At the same time, you can easily raise the pedal height. Small holes are drilled in the axle. The locking screws go to them. With this system, the shaft will never loose again.

    I don't think, sequence matters. What matters is, that connecting parallel battery packs must only be done when all packs are at the same charge level. So, we need to meter the voltage of every individual pack first and as long as we find any significant difference, they must be charged to a similar level individually before connecting them. I'd be worried with any voltage difference >0.2V between the packs (hi experts, please correct me). EDIT: If you don't have a volt meter but you are desperate to put your wheel back together, you can connect the first pack (and only the first one), charge it to green light, disconnect the first pack and repeat that individual charging with all other packs - one after the other. Only when all packs are charged to green, start connecting them in parallel.

    I think giving people a quick go on an EUC puts more people off. Example: I let my son's friends try my TGT3. None of them bought an EUC. Maybe they are just middle schoolers without $$$. Example: I let a couple of my friends/neighbors to try it, none of them bought EUCs either. Example: One day, I rode passing a house under construction. The workers there asked about EUC and want to try . I was riding my new Msuper and I did not want them to damage it. So I told them this is my NEW and expensive toy. I do not want it scratched. I showed them how to ride. I told them I have another one which I only ask $150 to buy. I told them that just the battery alone cost more than that. They knew that Li-Ion packs were expensive, because they use power tools. So they bought my used TGT3, shared by 3 workers, without trying out first. Two weeks after, I passed that construction site again and talked to them. None of them were able to ride yet.

    Obsolete? Pishaw! Times may change, but never think you're obsolete. Your students and peers are going to be amazed once you get riding the Ninebot. Many people even would not dare try it let alone attempt it at your age. Would anyone consider Fred Astaire's dancing abilities obsolete? The classic knowledge, skill, and principles are where we came from. I don't think the fundamentals of sound knowledge and experience can ever be considered obsolete. They got us to where we are today, and although some may forgo mindful engineering principles to save a buck or two, they end up realizing sooner or later that there is wisdom and value in following proper design elements and principles. Welcome to the forums, and safe riding!

    UPDATE: After speaking with Tina(a KS representative) she told me to kindly speak with Carey (engineer at KS) since I spoke mandarin we had no language barriers. All comments were thoroughly explained to Carey and he tentatively listened and responded. 1. Speed should not be reduced We can increase the speed to not allow any speed drops after 50% for KS16-a/b/c Available in the next firmware update v1.25 to be made AVAILABLE TODAY (Feb 27, 2017) HOWEVER it is not possible for any other KS-14 and KS18 wheels due to the safety factor. Carey went on to explain how the wheel would not withstand aggressive accelerations if the speed limit drops. 2. Customizations on Alarms Carey understood and will try to implement these. However Alarms 1 and 2 can be turned off when set to 0 3. Light setting should save The light setting can not save due to the way the motherboard on the wheels are engineered. However it is possible for the newer KS wheels (KS16s). For existing KS16 wheels you may turn on the bluetooth and if the lights are on quickly push the bluetooth button (whilst its on) for around 1 second to turn off the lights. 4. Lights locked in place/ not alternating Carey said this is doable and will be put out soon. 5. Wheel does not "spin out" when lifted off the ground Not possible due to the engineering of the trolley handle. Because there is no sensor for the handle the wheel can not come to a stop when lifted off the ground. 6. More customizations on pedal tilt Was considered 7. Bluetooth Password Understood by Carey 8. Rename KS device name Understood by Carey 9. Headlights Brighter lights are available on the newer KS wheels More Flashing options for existing wheels will be considered 10. Firmware updates consume more power Carey said that this is definitely not true. It may appear as such on Wheellog because the wheel has faster acceleration due to the new V1.23 update.

    After 5 hours of learning to ride my Ninebot One E+, this is the state my ankles are in: It's so painful to get on and off now that I have made some cheap ankle guards using materials I had at home. These are made from foam sheet that has thin plastic on one side, some Baltic birch plywood and some elastic velcro straps from the dollar store. These are worn on the inner ankles to protect against the constant pressure of the EUC when getting on and off and turning.

    7805 won't work, it's a 5V regulator and needs something like about 2-3 diode drops (roughly 1.2-2V) higher input voltage (datasheet says 7V) to even work properly. There are 3.3V, 3V and 2.5V LDO ("low dropout", meaning the input voltage won't need to be that much above the regulated output voltage) available. BUT, since the EL-wire seems to draw more current than at least the smaller linear regulators (TO-92 -packaged, typically 100mA max) are able to withstand, you might need a more heavily packaged one. Or use a switching step-down converter, which wastes less power and doesn't heat up as much. Do note that you can't stick a normal voltage regulator directly into a 67.2V pack, it can't handle the voltage. That's just in case you end up going with taking the power from the USB-port. Don't bother with relays, if the lights don't draw amperes of current, a simple power switch (just checking through the switches I have, they're rated between 2 and 10A continuous) or a power mosfet should work for this... If both the EL-wire and the lights need to be behind one button, it requires some circuitry, as the EL-wire inverter seems to turn on/switch stages (on - blinking slow - blinking fast - off) by getting a signal from the switch, so the light circuit would need to be triggered from there also. Don't recall ever seeing a battery configuration like that before... The XT60-plug is likely the discharge-side, but where do all those connectors go, into the mainboard? It's hard to tell from the picture even how many wires are going to the connectors. Since there's only one wire going from one pack to the next, I'd guess the packs themselves are in series, so it might be possible to break them down into lower voltage packs (but that's not probably for the faint of heart). Be careful with the batteries anyway, even if they're "empty", they still pack quite a punch. As for the EL-wires themselves, I took apart the 2 x AA -battery driven unit I have and poked around. There's a few apparently "optional" resistors that are left out (and a place for a diode and larger capacitor on the other side, that weren't there either, saving on costs ). Couldn't identify the chip in the middle (it has marking "6612", but no part having that number had a pinout that made sense with how this circuit is built). Based on http://ch00ftech.com/2012/03/25/el-wire-is-spanish-for-the-wire/ , it might be some small low-cost microcontroller, that's basically just handling the changing between the on-blinking-off -states.This one doesn't have that secondary transistor like the one that ch00ftech took apart, but a few scribblings of the circuit I made into a paper, it looks like it's a different topology than on the one that he had... I didn't try to figure out the circuitry that much, since I don't know what the chip does (at least one pin from it goes straight into the transformer coil, so it's not just to start/excite an analog oscillator there?). On the other side's theres a single PNP SS8550 -transistor (don't know why ch00ftech says it's a P-channel FET?), the transformer coil with center-tapped coil on primary side, and the power button. A "fun" thing I noticed, I first thought that the microswitch is soldered on all four points, and will short the positive input straight into the negative when pressed, but the pin marked as "WTF?!!" is actually unconnected If it weren't, or it somehow gets contact with the surrounding copper, pushing the button would cause the circuit to connect through the blue lines I drew, shorting the positive input straight into negative... But instead, it just pulls the pin 3 of the IC to ground (there's a 10k pullup resistor keeping it high when the switch is not pushed), so that's what switches the state (on -> blinking fast -> blinking slow -> off) when the pin is triggered from high to low. Anyway, the main point was to take some measurements from the damn thing. I first hooked it up to a power supply with overcurrent protection (CC/CV) set at 3V and working the current up from 100mA, so I won't fry anything by accident and to see how much current it draws... seems to be about 195ma (0.195A) at start, and going slightly above 200mA after things warm up. The secondary coil of the transformer puts up quite a hefty voltage. With 3V input, I measured 107V AC RMS with the benchtop-meter, and after knowing it won't blow up my scope front-ends or meters, I then measured closer to 300V peak-to-peak on oscilloscope, the oscillator is running around 1.5kHz. The annoying sound the inverter makes is probably the base frequency resonating in the coil... Yeah, don't touch the output wires... although it probably won't give much current, you'll likely get a good zap at least. On the input side, there's some noise visible, at the same frequency: Probably adding that missing capacitor would filter most of it out... I was using an EL-"tape" (thin, but wide, not actual "wire") as load for the measurements shown, but found out later that using a blue-colored EL-wire that the voltage goes even higher (with 3V input, about 130V RMS / 370V peak-to-peak, but "only" about 100mA of current)... Raising the input voltage from 3V to 3.3V, the voltage went up to 145V RMS / 410Vpp. I didn't want to go higher so I don't break something. The inverter's unregulated, so probably it would self-destruct by driving the voltage to some insane value if driven without load or with higher input voltage (unless the IC there has some sort of protection for that), which wouldn't be a big deal, but risking damage to the scope front-end or my benchmeter is not something I want to try, in case there's some freak high-voltage transient Since it seems that the current varies between different wires and of course lengths, it's probably best to assume that the current can be relatively high (several hundreds of milliamperes, better over- than underestimate, make it a nice 0.5A? ). I have no idea how much current you can pull from the USB-port of the wheel (if using that), but likely at least 0.5A. Can't vouch on that, so if your board fries, don't blame me I'm just a hobbyist on electronics... At least in the case of this inverter, also the output voltage raises fast with input voltage, and I don't know how much input voltage the IC can stand (or what kind yours is anyway), so probably best to keep the input voltage at 3...3.3V max (that's about what two full AA -batteries in series give), I also don't know how much voltage the EL-wires themselves can stand, but they probably burn out faster with higher voltage? They do wear out anyway, so maybe plan the attachment so that you can replace them: On average El Wire brightness will become half as bright after 2800 - 3000 hours running at 2000Hz. This is based on 6 to 8 hours on each day and powered off the rest of the day. A high Hz output from the inverter makes the El Wire brighter but it also shortens the life if it. For example, if an inverter runs at 10,000 Hz EL Wire will become half as bright at about 450 hours. Although, if it's being run at around 1.5-2kHz (my inverter's different than yours, so I don't know what the frequency in yours is), closer to 3000 hours is plenty. You'd either need at least a TO-220 -packaged linear regulator (possibly with a heat-sink) and some filtering capacitors, or a switching buck-converter (there I can't help, designing those is way out of my league, at least at this point) to drop the 5V from the USB port to 3 or 3.3V. I have no idea how good or bad the ebay/aliexpress/whatever cheap converters are, they might work, but again I can't give any guarantees... Other options include a heavy-duty step-down to drop the voltage from the battery directly (but that's up to 67.2V for full battery), so it's the bulkiest and most expensive (at least for better quality) option. Just as an example, probably about the simplest setup with a linear regulator would be something like: The diodes may not even be necessary (I picked 1N4007 just because that's what I've usually used in such ), a fuse might not be a bad idea just in case... I marked the output capacitor (C2) as "100uF or more", simply based on the datasheet recommendations for LT1117: The LT1117 family of regulators requires an output capacitor as part of the device frequency compensation. A minimum of 10μF of tantalum or 50μF of aluminum electrolytic is required. The ESR of the output capacitor should be less than 0.5Ω. Normally, capacitor values on the order of 100μF are used in the output of many regulators to ensure good load transient response with large load current changes. Output capacitance can be increased without limit and larger values of output capacitance further improve stability and transient response. I put D1 there "just in case" a higher voltage transient somehow kicks back from the inverter, although my measurements with the scope didn't show such happening. Probably could be left out as well. As for the D2-diode: Diodes between input and output are not usually needed. The internal diode between the output and input pins of the device can withstand microsecond surge currents of 10A to 20A. Normal power supply cycling can not generate currents of this magnitude. Only with extremely large output capacitors, such as 1000μF and larger, and with the input pin instantaneously shorted to ground can damage occur. A crowbar circuit at the input of the LT1117 in combination with a large output capacitor could generate currents large enough to cause damage. In this case a diode from output to input is recommended So, technically, with low output capacitance, the diode wouldn't be needed. At pure-guess worst-case continuous current of 0.5A, the power dissipation at the U1 (with D1) would be around (5V - 0.7V - 3.3V) * 0.5A = 0.5W. The TO-220 -packaged regulator might work even without a heatsink at that point. Without the D1-diode, the power dissipation goes a bit higher at 0.5A, about 0.85W, in which case a heatsink might already be needed. Either way, adding a heatsink on the thing won't hurt. I don't know how much you know of electronics, if you can't or don't want to build your own circuits on a veroboard or such, it's probably much easier to go with a ready-made switching buck-converter. If you want your (separate) lights to turn on with the EL-wires, then you're likely going to have to build a circuit from separate components. I can help with that, but won't start designing one right now

    Another 14C outleaned (admittedly at 20 mph so I guess you can't blame the wheel).... Did you have wrist guards/gloves or any other protection besides the helmet? What are your injuries? Did you have an old firmware? From what I gathered the new 1.25 has better safety/would probably stop you from doing what you did. Well, get better and thanks for the "experiment". It's funny how either everything goes right or you have catastrophic failure with EUCs, but there are no intermediate steps. I have to admit I only understood this after a (thankfully slow) crash too. It's just very unintuitive that "working oneself up" to crashes isn't really possible and you can't test the waters.

    If the KS App & QC were better I'd unhesitatingly recommend the 14D. But it's completely stupid requiring new (non-technical) Users required to make permission changes to Android because KS are too lazy to add a checkbox during compilation. There's a whole slew of minor niggles I have with this Wheel that's preventing me from investing in an order. Range is going to be less than the V5F+, the 14D only has 32 cells as against Inmotion's 40.

    That looks much better (sigh of relief). Explanation: Our batteries have a very low "internal resistance" and deliver a very high current when shortened. Connecting two battery packs with a significantly different charging state is very close to a short circuit. Say, at 60V and some 35A flowing, there's a sudden heat source worth >1000 Watt - concentrated at a tiny spot where the pins of your XT60 connectors touch. As a result it gets so hot, that the metal pins just melt away and sparks are flying all over the place. Meaning: you did not connect the wrong wires or magically plus and minus got reversed. Most likely, the connection you tried to close is exactly how it is meant to be wired. Just somehow between disassembly and re-assembly one of the packs was charged up or discharged while the other(s) maintained their charge level. Or did you buy a new pack and connected it the first time?

    Nice work, I have a tendency to forget the heat shrinks far too often, and then have to desolder the wire and start over Personally, I use a bit heavier gauge (as in, larger) soldering tip for the bigger connectors, and usually apply heat much longer... but the main thing is you get good connections. In case you sometimes work with "deeper" connectors (ie. where the "cup" the wire goes into is deeper), this trick works well ("preform/pre-filling"):

    No problem whatsoever. Happy to help. For starters, if you want the EL Lighting ON all the time, you can completely bypass the extra switch and just connect the Module directly to the USB port wiring. This way, they EL will be on every time the wheel is on. Since I only have 820Wh battery, and I like to ride LONG distances, I don't like to pull from the battery unless I decide to. Is that an extra Power Button, or the original Power Button that is still being used for the wheel? I have not tested the Pins on that switch to see if you can use two pins for another source and device. You could put a tester to it and find out. But, if all the pins are currently being used, you may not be able to use it and may need a secondary switch. IF you are using a second switch, take the GND from the Module to one side of the New Power Button. Take another wire from the other side of the power button to the GND wire on the USB Port. Take the RED + wire all the way from the Module to the USB Port. This will switch ON/OFF the Negative Side between the USB Port and the Module. That will power the Module on and off. On the Module, Ground SHOULD be black and Positive should be Red. But, if in doubt, you can open the Module and verify which wires are used. (That's what I did to be sure) In my drawing above, the wires coming out of the BOTTOM of the Module are the EL connections. I soldered mine, so you can ignore those if you are using a Y Adapter. You only need to deal with the power coming into the top of the Module.

    My take on this might be different to most here. I think it's a bad situation if a lot more people take up this hobby. When it remains a relatively rare and niche hobby or mode of transport, the law, the media and the public leave us alone to enjoy it. As soon as everyone buys one it's a problem, because "everyone" includes the retards. And they are the ones who will cause the accidents, the fires, the injuries and the negative public perception. The example I provide is drones. I am an avid RC model flyer. I used to fly quadcopters since before they were called drones and when you had to build them from scratch. I enjoyed the Phantoms and the small racing quads when they came along too. No one had a problem with these RC aircrafts in the early days. Then they went mainstream and the retards got hold of them and the media used them as another fear-driven profit generator. The result is that drones are perceived as a dangerous, privacy invading nuisance to society. I no longer fly them after numerous negative comments and evil looks, and I stick to RC planes. Other examples are laser pointers, psychadelic plants and research chemicals. Things that are useful and/or interesting but have some inherent risk, can become demonised, regulated and even illegal once popularity puts them in the hands of the retards. I would prefer EUCs and MiniPros to remain popular enough that companies are incentivised to improve designs and release new products periodically, while still remaining to be a niche enough hobby that the public rarely give these devices a second thought. I don't want to encourage many people to take this up.

    I experimented with my V8 today to see if the center of gravity (CoG) makes a difference (somewhere, I'd read that the wobbling occurs when your weight is forward or back of the contact patch on the EUC). In fact this is the case for me. If I move my feet too far back or forward on the pedals, with my CoG in back/forward of the contact patch, I get wobbles. The reason is clear to me. If e.g., the CoG is to the rear, any slight imbalance in the left and right foot will cause one side to dip; this will create a torque vector at 90 degrees that pushes the wheel to dip on the other side, and so forth in reverse ... the result is a series of wiggles that your feet are attempting to control. To get rid of it, make sure your hips are straight over the contact patch (your milage may vary, but it works for me).

    A Neil Armstrong quote...well almost! I think @esaj and @Carlos E Rodriguez might agree that taking the extra precaution and discharging the capacitors before making the final connection to the main board might be prudent to avoid Very good! The arming switch appears to be well designed. If the arming switch is too large I may just use the spark arrestor connectors instead. Darn...I thought I was correct!Your logic and the awesome diagrams make perfect sense! Thanks for taking the time to explain! Visuals always help! The analogy works in this scenario! As much as I like science and unless someone else would like to try to recreate the scenario I will connect the battery packs first and then the main board with the spark arrestor.

    Hallo @man-on(e)-wheel, erstmal auch von mir Gute Besserung! Dann ein paar Empfehlungen: Schreibe ab jetzt nichts von dem Verfahren, alle Aussagen wie "Der Depp hat mir die Vorfahrt genommen" gehören nicht hier her, sondern in deine eventuelle Aussage. In einer eventuell stattfindenden Gerichtsverhandlung kann dir das zum Nachteil gereicht werden. Wenn das Verfahren mit einem Strafbefehl, Einstellung bzw. Verurteilung endet, kannst du das dann gerne hier veröffentlichen (anonymisiert). Suche dir einen Anwalt, der auf Verkehrsrecht spezialisiert ist. (ganz Wichtig! Dir nützt kein Familienrechtrichter, auch wenn der aus deinem Freundeskreis kommt.) Hilf dem Anwalt indem du ihm auf die tatsächlichen Gegebenheiten, wie die verschiedenen Gutachten zum Monowheel, aufmerksam machst (Dilemma Pflichtversicherung: Polizei sieht es als KFZ, Versicherung / EU als Sportgerät = Versicherungsfrei). Bespreche mit ihm das zu erreichende Ziel. Der Anwalt kann dir dann auch sagen, mit welcher Wahrscheinlichkeit das Ziel erreicht werden kann. Kann er dies nicht, gehe zum nächsten Anwalt. Solange du kein Anwalt hast, rede nicht mit der Polizei. Sag ihm aber nicht einfach nichts, sondern das du noch einen Anwalt suchst und dieser dann den Kontakt sucht. Befolge den Anwalt. Wenn er meint, nichts auszusagen, dann sage nichts aus. Der Anwalt hat eine Strategie die er eigentlich mit dir auch vorher bespricht. Es ist leider schon so oft passiert, dass die Klienten des Anwalts dann irgendwoher von einem anderen eine neue Idee ins Ohr gesetzt bekommen haben und die Strategie des aktuellen Anwalts torpedieren. Du bist dabei immer der Verlierer. Wenn die Polizei dich vorlädt, gehe mit deinem Anwalt auch hin. Das ist ein erster Termin dem Staatsanwalt zu zeigen, dass du nicht unverbesserlich bist. Wenn die Polizei dir ein Befragungsbogen schickt, beantworte diesen auch mit deinem Anwalt zusammen. Nicht einfach ignorieren, weil alle sagen der Polizei sagt man nichts, erst dem Richter. Wenn es aber so weit gekommen ist, ist es auch nur noch schwer rauszukommen. Am Ende schreibt die Polizei ein Bericht an die Staatsanwaltschaft. Ziel sollte es sein, schon die Staatsanwaltschaft zu überzeugen, keine Anklage zu erheben, sondern das Verfahren nach § 153 STPO einzustellen (siehe: https://fachanwalt-fuer-strafrecht-bundesweit.de/blog/einstellung-eines-strafverfahrens-gem-153-stpo/). Vorteil: Keine Gerichtsverhandlung. Nachteil: Wir anderen Monowheel – Fahrer leben weiter in Angst. Viel Glück, und bitte nimm es nicht auf die leichte Schulter und mach es ohne Anwalt. Wenn alles schief geht, bist du am Ende vorbestraft und 1600 Euro ärmer. Gruß, Teran Anlage: Hier ein Beispiel von einem Hoverboardfahrer: „AG Düsseldorf: Hoverboardfahrer kommt mit Geldstrafe auf Bewährung davon Der Fahrer eines sogenannten Hoverboards muss einen Strafbefehl in Höhe von 1.200 Euro nicht zahlen. Das Amtsgericht Düsseldorf verurteilte den 40-Jährigen am 17.11.2016 in einem der ersten Verfahren um die Nutzung der Geräte im Straßenverkehr zu einer Geldstrafe in Höhe von 450 Euro auf Bewährung. Der Hoverboardfahrer hatte dem Strafbefehl zuvor widersprochen. Fahrlässiger Gebrauch unversicherten Kfz - aber kein Fahren ohne Fahrerlaubnis Der Mann war mit dem elektrischen Gefährt im Sommer 2016 in Düsseldorf auf einem Bürgersteig unterwegs gewesen, als ihn die Polizei erwischte. Die durch Gewichtsverlagerung gesteuerten Hoverboards sind im Straßenverkehr nicht zugelassen. Zwar habe sich der 40-Jährige des fahrlässigen Gebrauchs eines unversicherten Kraftfahrzeugs schuldig gemacht, erklärte der Amtsrichter am 17.11.2016. Allerdings konnte der Web-Entwickler dem Gericht einen gültigen Führerschein vorlegen. Daher sei der Düsseldorfer anders als von der Anklage angenommen nicht ohne Fahrerlaubnis unterwegs gewesen.
