    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.

    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

    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.

    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.

    Just for you @Rehab1 I took the raw footage and made a nice slow-motion film of the crash. The back-and-forth oscillation can clearly be seen right before I'm ejected. You can also clearly hear the single beep before it cuts out. For grins, watch my feet fly thru the air at the end

    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.

    5 reported accidents so far. my friend included. 20 ish kmh on flat road and the wheel just cut power after a few seconds with on and off. his face is not pretty right now. Could everyone with the same batchnumber report in and also if you had a problem. thanks Moderator notice, June 24th 2017: Apparently motorcode is not a reliable way to know if your wheel is affected, the motors might have numbers going back to 2016 (like 1608) and still be affected. Basically if you've bought an MSuper, ACM (and/or maybe Monster) since sometime in start of May 2017, your wheel might be affected. You need some other way to establish when the wheel was built, apparently there's another code somewhere, maybe on the box it was shipped with. 1705 (2017 05, 2017 May) seems to be the magic number, basically any way to make sure that your wheel was or wasn't built after beginning of May. So far it appears that the software goes haywire after riding over a bump. For some riders, this has happened at low speeds, but others report it only occurring at high speed. The wheel is reported to start oscillating back and forth and cut out soon after (maybe in a matter of <0.5 seconds), leading either to crash or the rider jumping off. There seems to be no warning before it happens. Gotway claimed the problem was solved and sent out new replacement boards that should have been OK. That was not the case, the problems still seems to remain, only maybe with higher speed now? At the time of this writing, apparently even brand new wheels still have the issue. Suggesting everyone with the affected wheels to stay off them until Gotway has fixed the firmware for sure, and your dealer gets the equipment and the binaries required to flash a fixed firmware to the board (or new boards with new firmware). This video was shot by @Marty Backe with a board that was supposed to be fixed:

    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

    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

    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.

    I'm posting a video shortly. My wrist and shoulder is messed up. I have my oscillation crash on video - what fun I feel bad for Jason. I wouldn't recommend anyone ride a new ACM or MSuper right now. More to follow in new post...

    Since Gotway is known for pushing the limits, many people buy their wheels and then proceed to test the limits and many crash as a result. KingSong does not have that reputation so you don't see people trying to push the KingSong wheels to their limits. So regarding high-speed cutouts I think it's a little unfair to pile on Gotway. I still think the vast majority of Gotway owners never have any problems with their wheels. It's human nature for us to complain when something doesn't work as expected. Yet we all know that most people don't write posts like, "My Wheel Continues To Operate Perfectly". So we can get this false sense that Gotway just produces crap. I just don't buy it. I'm going to start publishing more positive stories (i.e., boring) to try and balance things out

    @dalewalker Think you should stop now, you're only making yourself and your store look bad. Many of us on here who have experienced @Jason McNeil's exemplary service via eWheels.com & WheelGo.com know he goes above and beyond just being a seller; he proves he truly cares about the betterment of EUC and EUC culture in general, when other EUC middle-men distributors leave you in the dust post-purchase. Jason helped me with my KS18A issues when I hadn't even purchased a single thing from him, let alone the KS18. Through my many subsequent purchases through him, I've only experienced the same A+ service, nothing less. I don't know what level of dealer you are, and you might be an excellent one, but your posts do not reflect this when you go after such a highly vetted, highly regarded contributor / distributor on these forums.

    Hello guys! My name is Uliana. I am russian girl, 22 y.o. i'm going to a trip across Europe, starting from Riga, going to Madrid, Spain on the electric unicycle. I am planning to ride about 100-150 km/per a day, with a speed about 25-30 km/h. Making some videos during the way, and paint pictures, when i will find beautifel places. That's a plan 😜 And maybe i will need some help on my way (i hope to won't need it, but who knows) with the wheel. If it will be broken or smthg like that, so please, if someone from u could help me, let me know, please. And if someone could host me, it would be amazing! 🙃 or maybe show me your city - i will be thankfull and happy 😁 And, yes, if you want to join, i am open, just write to me and let me know. Start from 3rd July. Thank you 😁

    Have had my Mavic Pro for about a month now and I'm getting the hang of flying it while riding. It makes it even easier whenever I just have it follow me automatically for some nice smooth dynamic shots like you see here. Top speed is 40 mph so it has enough speed to keep on with my MSuper V3s+ especially in my profile shot of me going 26 mph. Ran into a couple of Boosted boards in Dallas which you see at the end.

    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.

    I finally have an i5 in my hands! I wanted to make a post to document the process as I test it as well as to try and answer any questions the community has. If there is a certain test or questions please ask and I will try to get everything answered. Currently waiting for the battery to charge before I start recording and testing. Super excited. First impression is that it is unbelievably thin. The width is almost identical to a standard glass bottle. IBC Root beer tested. It also is definitely light, I haven't weighed it yet but the shipping weight was 22 pounds as a whole so it seems to be on par with IPS claims.

    My KS16S 840Wh arrived yesterday evening and here are my initial impressions. I ordered this directly from King Song on the 9th and it arrived on the evening of the 29th. So those of you who are impatient might do best to order it from a local supplier instead Apart from the wheel, there’s nothing much in the box; a flimsy manual and of course a charger, but nothing else. However, the wheel itself looks absolutely gorgeous and gives a quite high quality impression. I ordered the rubber black version and it is very nice to the touch. The serial number starts with “KS16 S2 D …” but I do not know if this means it is already somehow a second iteration on the KS16S or if they all have this model number. I took it out for a short 8 km ride yesterday, but today it started raining so apart from a short early morning trip unfortunately I will have to wait until tomorrow to ride more. Luckily, the wheel arrived with 50% charge so I could immediately take it out for a spin. I had no problem whatsoever to just jump on it and go, although the feeling is a bit different from my other wheels. it seems to have a lot of the manoeuvrability from my IPS Zero but is much easier to balance than the Zero it has the same feeling of heft as my Xima Lhotz although it feels marginally less steady due to having a slightly narrower tire When driving, the sides lit up like disco lights. I am happy that the light show can be turned off in the app. Bling is not my thing. There is also a quite loud “Hello King Song” voice when you start it up - and I soon hit the preset 18km/h preset with the voice going “Please decelerate” so loudly that people around me looked up in surprise. Luckily the voice warnings can be switched to beeps in the app, but unfortunately that cannot be done with the welcoming message. I wish they could have a startup sound as an alternative. Speaking of the app, it is much better than the previous apps I have had. I like the fact that the (iPhone) app tells you how much riding distance you have left - but I wonder if that is just a hard-coded conversion of the battery level or if the app actually takes some of the riding stats it collects into the calculation. It should if it doesn’t already!! The riding mode was initially set to “player” mode which compared to the other wheels I have had is very stiff in the sense that it keeps the foot pedals more or less horizontal. I have read that some have trouble with pressing the foot pedals forward, and do not think acceleration is good. I believe that might be because they are riding the EUC in “player” mode. i switched the setting to “cycling” mode instead and then the pedals can be tilted more forward when accelerating. And, importantly, they can be tilted backwards when braking - something which I found a bit challenging in “player” mode. There is also a softer “learning” mode that I have not tried. Since it was getting dark as I was riding, I noticed that the light sensors automatically turned on the headlight - a nice touch! Speaking of nice touches, the retractable handle is really superb. I was getting tired of always having to carry around my wheel and although the Xima was maybe a couple of kilos lighter, it was still a pain. Now I can roll my KingSong with me when going shopping, for example - great!! On the less positive side, there is a very distinct high-pitched whining noise that I never experienced on the IPS Zero or the Xima Lhotz. A bit annoying, I must say - but I understand that this is quite common with newer wheels. Also, the manual is a mess. It would seem such a simple thing to maybe ask someone on this forum to clean up the English a bit. Maybe they could also supply a link to a more up-to-date digital version of it. The “cycling” mode in the app is not even mentioned in the manual, for example. The manual also says that you should “use the inflation tube” when filling air in the tire - there isn’t one and you do not need one. Overall: I was choosing between the King Song 16S and the Gotway ACM, and right now I feel that I really made the right decision. I don’t want to go faster than 35 km/h since I rather cruise and use less protective gear than try to get myself killed speeding to the max. I get the impression that King Song are focusing more on reliability and staying within the limits here - and that is exactly what I want. Also, after just one day, I already no longer understand how I could live without an integrated handle before!

    First time out on the new wheel. She also hasn't rode a wheel in some time so you might give her a break. We have been riding around town since this and she has grown really fond of it. I will get a few more local riders opinions when I get the chance.

    First off, welcome to the forums, and sorry to hear about your accident. Where did you get the impression that Solowheel was the best? I think there are still some fans, but they seem to be few and far between due to the high cost to features ratio mainly. There is a new Solowheel Scorpion due out plus some interesting things from InMotion/Solowheel joint ventures. Exceeding the acceleration maximum of any wheel is bound for failure as the motor just can't perform miracles. If you're near the upper limits of speed already, and you try to accelerate quickly that may use up what power the motor has left without any ability to warn you or tilt back. Tiltback requires that the wheel accelerate a bit to adjust the tilt of the pedals/shell so it needs to put out a burst of power. If that extra burst isn't available it will cut out. Imagine your best athletic friend is pushing you while you balance over the wheel on a wheelbarrow. He's running near his maximum speed to catch your slight lean so you don't fall forwards. You decide to suddenly lean even more forwards, and he just doesn't have any more umph to push faster so you meet the ground. Up near the upper speed limits is where the danger zone is. I would advise against any sudden movements up there that may exceed the available power that the wheel has left to keep you safely balanced. The upper limit will also vary with battery charge level, rider weight, wind, and inclination of road so it's not really a well defined speed setpoint. In the future with much more powerful motors that are over-engineered, we may see one day that there is plenty of reserve energy from the motor/batteries to handle almost any situation demanded of it, but that day is still far away. As you reach the top speed for your weight and riding conditions, torque approaches zero. When torque reaches zero, you reach the ground at full speed. 26 pounds is on the light side for wheels. My Ninebot One E+ weights about 25 pounds. How much do you weigh? If you're on the lighter side, maybe an Imotion V5+ or V8 might be a good choice or a Gotway MCM4/KingSong 14C? It's difficult to find something lighter than 26 pounds that is still pretty good. Maybe a Ninebot S2 or the new IPS i5?

    Got some additional info from GW this morning: They claim that this is the first time they've heard of these problems They're trying to gather the Motor Codes of effected units to assess if it's a batch problem It could be a firmware, at this point they're not certain The motor wire tubing is a new addition from mid-May

    As most already know I've had an operation for problems with my spine. I used to walk or cycle a hundred plus miles per week, including just over 2 miles each way to and from work - sometimes taking the longer, more scenic 5.5 mile route. I love being outside in the fresh air. My spine problem and possible nerve damage has meant I haven't been able to walk/cycle for 3 or 4 years now. After my op, which helped but didn't fully resolve the issue, I decided to look into other ways to get out and about - other than a mobility scooter seeing as I can still stand - as I don't drive either. For the past 2 years I have been getting about on an EUC. I started with a Ninebot One E+ 320wh then upgraded to a Gotway ACM 820wh and, once it's repaired, I also have a Gotway Monster for the longer cruises.

    Late last night Linnea revealed more details into the nature of the fault: the Engineer(s) thought it would be a good idea to implement current limiting (exact code snippet please?!) in an attempt to mitigate the type MOSFET of burnouts that Marty recorded on his ACM during that steep hill climb only a couple days earlier—obviously not from that specific example, but from a handful of other Users. I don't think it's fair for Marty to be the unofficial test pilot for GW Wheels Heading out to LA on Thursday to get started on this project. When dealing product safety, monetary considerations are subordinated to reliability.

    In another recent GW dialog, I stipulated that a minimum requirement for future order is that the BT module has the capability to pull the FW version from the board. Apparently it's not possible, because the module does not have low level function access. Compromise position is that the FW rev number will be printed on the box label. Similarly, I request that Distributors be given instructions/equipment for flashing when necessary. They're reluctant (in fact refused!) on the basis that the code could then potentially be used by rivals—in this existential crisis of credibility, this is the least of their worries right now!

    Just returned from LA last evening with the objective of testing out the latest ACMs+ & MSupers that arrived from GW. Received the Wheels on Tuesday, opened one up to check the serial/date of the board, it had 170502. Immediately wrote to Linnea to get some confirmation on the state of the FW, since the date evidence directly contradicted earlier statements... She assured me that the boards had been reflashed the day before they were shipped out (see the below thread).. But that wasn't sufficient for me, I padded up & took a new ACMS+ out on a pretty gruelling trial ride with @Marty Backe & @Sven. The Wheel held up well with no apparent vices. Shipped the Wheels out yesterday as was planned. Today however, Marty reported this his MSuper is afflicted by oscillation fault! Conclusion is that either a) GW have no idea what's going on, 'b) they blatantly lied to me to avoid dealing with the after-service troubles. We're going to try to get some more answers this evening, but the Wheels shipped out yesterday are going to have to be recalled. ME: Linnea, I have serious doubts of what you tell me is true. Look at the below message you sent on May 16th, these control-boards are dated 2nd of May. It is the date of the board manufacturing & NOT that when the Wheels were shipped that matters. Please confirm ASAP!!! EARLIER LINNEA STATEMENT: "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. " LINNEA: We promise that your wheels are not within that batch of problem mainboard. You know that we upgrade the firmware at that day before shipped out your wheels. Just upgrading the firmware, but not changing mainboard! So the original mainboard label is still there. ME: If what you tell me is true, I will love you forever LINNEA: You may confirm it with the shipper too, I told her that we are upgrading firmware with your wheels at that day when she push me to pick up goods.

    (If it looks like not all pictures load, reload [F5] until they do) BIG BATTERIES ARE AWESOME! Electric unicycles are awesome! ACM is awesome! Night rides are awesome! Did a 57km, over 6 hour (including breaks), mostly unplanned ride. Here's the story: So yesterday, after mignight, it was so hot I spontaneously decided to do a short night ride to cool off. Well, not so short as I went for a scenic church on a foothill at the base of the mountains, 15km from and 350m above home. This one (pic from Wikipedia): Mountains where you see them (and to the left), valley to the right of what's in the picture, 350m below you, great views! Being 1am, it was dark night though (so not too many photos here, and a lot of text). Only the ACM's meek light to see the ground before you when there were no street lights or other illumination. The first theme of the ride (in hindsight) is, "Wait, is this path getting even worse?". First started when, after riding through empty streets, doing a small detour along a lake. The path quickly went from farm road to overgrown footpath to dodging and curving around trees and their roots on wavy terrain (as well as collecting surprisingly many spiderwebs with my face), with the lake and whatever canals to the sides. You can't see them, but you hear there's water when a frog jumps into safety or there's a little splash here and there. But with an electric unicycle, easily done, and fun. After a while, I reached paved roads again. On it went, on deserted streets, through fields, or right through villages, nobody to be seen. Night rides have their special quality! And it was nice and cool. Upon reaching the base of the mountain, my personal new hobby began: worrying about my motor cabling and the current produced. Inclines were quite steep, 15% in many places, 20A says the specification, 30A or 40A says the wheel when going up. Oh well! This can be done by doing breaks every few minutes, to prevent possible overheating. Took very many screenshots of the Wheellog current chart on the way up [more about that topic some other time]. Besides this, the rest of the ride uphill was fantastic, through pitch black forest, through meadows with the lights of the valley below you, passing neat farm settlements along the path up. On a nice, smooth road. Finally reached the destination, on the ridge of the hill. The church is on a small elevation above the street, a big tree next to it, with a bench under its branches. Great views of the valley, lights of the villages and Autobahn laid out before you, the faint silhouettes of the mountains behind you in the dark. Unfortunately, neither my phone nor the old camcorder I took with me could make a decent picture (the latter gives you nightvision pictures though). Phone pic of the view. Same view. Camcorder pic of the lights in the valley. Well some of them. I expected the church to be spot-lighted as it usually is, but it was not. Second theme of the ride reared its head: "This is more creepy than I expected!". Very dark, cold wind from the mountains, and as customary, a cemetary with the church. The entrance being a few steps behind the bench I sat on. While my naked eye could see nothing besides a tiny candle in there, thanks to the flash, here are some official creepy-vision pictures for your enjoyment. With ACM, of course. Phone pic with flash. These are the kind of pictures where you photograph into the darkness, and expect some undead staring back at you once you look at them later. Fortunately, didn't happen Relaxing in the dark. After some time trying (and failing) to get decent pictures of the lights in the night, I continued on. It was 2:30 am at the time. Being on a ridge, I rode the road along it, to a small chapel with a view similar to the church. Didn't stay long as the wind was howling there and there were people not to be disturbed, so no pictures. If you're wondering, there are a ton of churches, chapels, shrines in the area; typical for rural Bavarian areas. Back along the ridge, passing the church, I decided to descend another side of the hill. I started to use my phone for navigation. This was meant mainly to prevent going on the main roads as much as possible (though in hindsight, there was barely any traffic to be seen, maybe 2 or 3 cars altogether). So on it went, downhills, descending through meadows and neat little farms and villages. All nice, wide paved roads. After branching from the main road, the route became increasingly side-path-y, smaller roads, more curves, until suddenly the pavement ended and I was on a farm road. And there was a fork. The navigation told me to go right, but it turned out the path ended at some trees, with only a narrow breach, overgrown with tall grass, to follow through a forest. Too much to decently ride, even with a EUC. So back to the fork, and going the other way. Surely, this had to be a better way forward. And better it was, though it would still hold some surprises (theme #1). The path went downhill steeper and steeper, through parts of forests and between steep meadowy hillsides. And always little to be seen besides the sky, the lights of the valley in the distance, and the trusty ACM's light cone to illuminate what's coming. Very much fun! Creepytime came again when I heard unexpected movement to the sides. Just some cows I woke up, though. Sorry, cows! Cows, plus valley lights in the distance. Then the narrow path got even steeper, and I did breaks every few minutes again, just to be sure my cabling stayed healthy. It was broken up concrete plates by now, overgrown with grass, and some deep cracks and potholes for extra challenge. And even steeper it became. Way too steep to turn around without having to carry the wheel up. Looking it up afterwards, it was up to 25% inclines. For a EUC, this is a lot. Even downhills. Right when the end of the last and craziest piece of incline could be seen, I underestimated an extra big crack, and gave some new battle scars to my mostly pristine ACM. Oh well... Anyways, finally I arrived at more level ground again. No more breaks necessary. But extra super creepytime. Picture this: an old farm in the pitch black dark, a loud dripping (?) sound seeming to come closer everytime you look in another direction, lots of scary looking sharp farm equipment, right out of a horror movie. And a Jesus statue, looking down at you. Took some photos by the light of the ACM and phone flash. Drip drip drip drip drip..... in the darkness. It's just a small, remote mountain farm, but not looking that harmless at night. Shed in the darkness, valley lights still some way below. Also, in the photo it looks like a EUC is leaning there Ninebot? Hey Jesus, how are you! To the right, steep incline I descended from. On the left, the path forward, only slightly inclined downwards. The path onwards was farm road, narrow but easily ridable. Here's a decent picture from a short part where it actually went up, to pass an old little farm. With another (creepy?) Jesus statue and chapel, naturally. I did not stop for a picture as not to possibly wake up the people there, it was still around 4am. You can see it's still quite steep on both sides of the path. It got steeper and broken-up concrete road again, so narrow and steep I was wondering if they could even drive a normal car up to their house. Then some sudden rustling. Some more cows to the side! They didn't seem to be bothered too much by me stopping and photographing, but when I put on my backpack again, that must have sounded like I was taking something out of it. All the cows came. In doubt, animals always want one thing from you: food You can always see the lights of the valley in the background. I had a fantastic view for the entire time (unless when in a piece of forest), the valley, the mountains in front of the sky, just an amazing atmosphere to ride in Some time later, passing another farm, it got creepy and funny at the same time. Sheep. Lots of them. And they got loud. Did you know, in the black darkness, sheep sound surprisingly human-like? Spooky! They all came when I stopped (take a guess what they hoped for). I quickly took a picture of the sheep/extraterrestials disguising themselves as sheep (look at them, you never know) and went on. They got so loud I was scared they'd wake up the entire farm (still pitch black night), thus the hurry. Left behind some clearly disappointed sounding sheep when I continued. Sheep, or Aliens? You decide. Some more descending, and it looked like I was almost down. Paved roads! Here's a shed along the way. As you can see, the sky finally got a little bright. Around 4:30 am. Reaching the base of the mountain, crossing the main road, I did a little break at a swimming lake next to the river. The weather was a bit too cold for swimming though, so I didn't (did that on some earlier night ride though, was fantastic!). ACM at the lake in the dawn. I continued towards home on the dam along the river, and it got brighter and brighter quite fast. It is summer, after all. These pictures are around 5am. Cute tiny trailer. No more pictures from the way home, as nothing much special happened and my phone battery was near 0%. It was mainly an issue of getting the 10 to 15 km home. But the ACM to the rescue, thanks to its USB port! Tip: always take your charging cable with you! Initially I wanted to make a stop for recharging the phone, until I realized I can do that without stopping. This photo was actually made by accident but this is how I continued. Being freed of the phone battery constraint (worried to lose my GPS track that was still recording), and not having had enough EUC riding yet, I decided to make as many detours as I could before the wheel would start beeping at me due to low battery. One of the detours, a short dead end in the forest, gave some more small battle scars to my ACM, and bent my phone's cable. Thanks to something hidden in the high grass. The ACM's USB port was not damaged though. Very sturdy little machine. Picture from today. I continued on, doing whatever detours came to mind, draining the battery. It's surprising at what comparably little stresses the wheel beeps at you with low battery. In the end, I had to go 15 km/h or less to prevent beeping at every small obstacle, hill, or acceleration. Finally, at 7 am, 6 hours and 15 minutes after I had left, I was home again. Tired but very happy. Not a single time did I worry about my battery status or not getting home, as I knew the ACM had plenty of juice left. I did not even start with a full wheel, probably at 85 or 90%. 57 km ridden, in what was initially meant to be a 2 or 3 hour ride. BIG BATTERIES ARE AWESOME! Here's the track. With time and distance ridden Start at the red Cyrillic letter and go clockwise. That's the end of the story. Hope you enjoyed. And learned something: in doubt, always go for the bigger battery. Absolutely worth it!

    A quick run down of what I have so far, my first wheel bought March was a Ninebot One E+ here is Australia with no research at all. Saw someone riding a EUC one day and was very intrigued so I looked up what they were. Saw a few youtube videos so I decide to get myself one without doing any research except on who had them for sale, the only seller who had stock was a Ninebot One dealer. I went and pick one up and only after buying it I knew I paid way over the top. After unboxing the wheel I used 15 minutes inside the house getting a feel for it in my hallway using both hands on the wall for support. 15 minutes later I decided to take it out and with 30 minutes I was able to go around the block felt very happy with myself, but my feet was killing me. Within a week or two the pain almost completely disappeared the body sure adopts to new stress points very quickly. The Ninebot One E+ is a great starter wheel for anyone wanting to learn it can take a lot of heavy drops, scraps mine got punished pretty bad while I was learning how to ride backwards. I don't regret getting it but in hindsight had I had know what I could of gotten for what I paid for it I would never have gotten it. If you are a starter I recommend getting a second hand Ninebot One E+ if you can find one around for cheap learn on it do whatever to it and once you're done sell it off to the next learner. I bought the Ninebot One E+ as a toy to play with but within 2 weeks I realised it was so much more, but the problem with it was the low speed and limited range. So this time I decided to do some research and stumbled across this forum, it is here I researched my next wheel. I wanted something which was powerful, fast and had a descent range as I had a 16 inch wheel already the choice was limited to KS and Gotway. Reading the Gotway forums I knew there were plenty of QC problems with them, Kingsong would have been a much better wheel for safety but in the end I chose the MSuper V3+ 1300 WH it was a lot more powerful had a higher speed and the integrated handle made it easy. I knew the risk of buying a Gotway right from the start so even if something happens to it or me I have no one to blame cause I chose it fully knowing some of the issues Gotway was having this was right at the time of the melting cables. One the 4th week of starting my MSuper arrived, it was matte black looked really good but boy was it heavy compared to the Ninebot One E+. The riding style was completely different to the Ninebot One E+, it took a few days to get use to the way it rides. Since having it I have ridden it to work almost everyday that hasn't rained and have completely neglected the poor Ninebot. The MSuper is such a beautiful wheel yes the motor is loud, but it is so comfortable, smooth and stable, I average close to 30kph and she purrs along ever so gently, I choose to ride in the powerful mode and nowadays I leave the other settings to the preset. I don't even hear the first alarm until 32kph. I am sort on the light side which helps being only 65 kilos and with my gear on around 70 kilos max. I have taken the MSuper to over 40+kph a few times even at this speed I haven't heard the final alarm maybe it is because of my weight. The MSuper does this speed so easily, I can see why it would be easy to get hurt badly so I recommend leaving it on the factory settings until you feel more comfortable even than anything over 30+ kph is stupid if you're not wearing full safety gear so please keep that in mind. The good thing about Gotway you can decide what you want, you are free to change the setting however you please actually this could be a bad thing also but hey the choice is yours. Six weeks ago I bought myself another wheel this time I wanted a lighter wheel which was faster and had a better range than the Ninebot but was nimble for riding around the crowded city. Wow this wheel was so hard to get, no one was selling it in Australia, I emailed a dealer in Singapore but the postage was almost the price was the wheel, I emailed Jason who was very nice with his prompt reply saying he doesn't ship to Australia due to high postage costs, I even called manufacturer and was told that they won't have a wheel till mid June and if I wanted one I had to pay and wait. After almost giving up I found a ali seller who had it for sale, so I bought one but it took almost 6 weeks to get to me but at least it turned up yesterday. The new wheel I got was the Inmotion V8 and yes it is the international version as my app works perfectly, my impressions so far after using it for a whole day. First off the wheel is beautiful I think it's the best looking wheel out of the ones I have, the pedal is also the grippiest of the lot. The front light is the brightest out of my 3 wheels, the side panel lighting show is also very bright and is customisable should you be into creating your own. I am 180cm tall and the integrated handle is such a good height unlike the MSuper which is a little on the low side, The button on the handle omg what a brilliant idea why don't all EUC's have this feature, the pedal height is great for a 16 inch wheel almost the same as my MSuper so it won't get too scratched. The negative is after pumping the wheel up to 55 psi the tyre scraps the front plastic every now and then so I had to reduce the tyre pressure to 45 psi in order to stop this, not sure if this is a bad design flaw or just me getting a bad wheel. I give it a few more days and if I find more negatives I will post otherwise that's about it. Now having had 3 wheel I can say without doubt the Ninebot One E+ is never going to be used by me again, thought I was going to play around with it but now it's time for me to try harder to get rid of it even at a great lose. The V8 is a great wheel for what I bought it for it will serve it's purpose and in the coming weeks I am sure it will grow on me a lot more. Having own the 3 wheels I can say without doubt why I love my Gotway Msuper, the V8 feels fast and scary for some strange reason at the max speed of 30kph where as the MSuper is just cruising along nicely. The V8 is pretty comfortable but in no way can it compare to the MSuper, I read some where people were saying the torque was good in the V8 going up hills not sure if we are talking about the same wheel but my MSuper will eat it up up any hill on any day of the week. I thought the V8 was going to be a fabulous wheel, but it is only a slight upgrade from the Ninebot E + in comparison to the MSuper. The MSuper takes the crown out of the 3 wheels I have, if I had a chance to ride the V8 before I bought it I might have not bought it at all, maybe I would have gotten a smaller 14 inch wheel which is just as fast and a lot more nimble. Whats next my sight is set on the monster by the end of this year, just have to sweet talk my wife up a bit more. Now I know why so many people are buying Gotways, they truly are in a class of their own I have tried a friends KS18 he bought recently but it's not to my liking can't compare with my MSuper. Here is hoping Gotway improves on the QC I also would love Gotway wheels to be safer after reading all the terrible incidents, so far I have around 850 kms on my MSuper and it's still feels terrific touch wood I am one of the lucky ones. As they make more money I am sure the quality will improve, but with any electronics there can always be problems with things going wrong. I bought a Asus GTX 850 graphics card when they first came out a few years back it was expensive and i happen to get a faulty card and I went to get it exchange I had the same problem. Had to wait a 2 weeks to get another replacement as that whole batch was bad. This is just a short brief and quick honest review based on my own personal experience, this is so addictive like drugs and it becomes more expensive over time one wheel is never enough.

    That's interesting Dale. Your prices are quite a bit higher than mine for the same products. Let's examine the KS16S, converted to USD you have it for $1600USD without any fast-charger or other options. We're offering the same Wheel with a $120 fast-charger for $1475. You might want to consider before making certain assumptions. https://www.thewheeldeal.net.au/ks16s.html How do you know Dale? How many times have you visited China? Been to any of the factories? Interviewed the Engineers? Besides riding the Wheel, do you do any testing yourself with a datalogger or thermal camera? Do you have any hard statistics on what the defect rate really is in large volumes? How many Wheels have you sold? From your interview in Australia, I think you said it was 15 total? Is that a sufficiently large number to make a categorical pronouncement? Yes Dale, but we are intelligent beings given the powers to set our own destinies. If you were better familiar with Business in that part of the world, having an agent inspect product is not very exceptional.

    I don't know from where you have the opinion that Solowheel is one of the best, but for sure not here from this forum. I have the impression, that most people here think, that currently the by far best wheels are built by Kingsong, Inmotion and Gotway, and I agree with that. E.g. I'm riding my KS16B now since more than 3000 km, also on steep hills, gravel roads and difficult terrain, and although it's upper limit is 30 km/h, I was going once with 39 km/h by overleaning to much, and there was no cut off (some people say the wheel has reserves that it could go even 45). It's no longer possible to go that fast with the latest firmware, because they changed tiltback in a way that one can only reach 35 or 36. But what I want to say is, that it is a very safe wheel, and I rely completely on it. They even changed the firmware recently, so that one can drive at the allowed limit (30 km/h) now until the battery capacity is down at 25% (it was 50% before), and then the maxspeed changes to 25 km/h. I can't speak about Gotways, but I tried Inmotion once, and if they would have a better range, then possibly I would own one now instead of the Kingsong, just because of the better App, and I liked the wheel hardware. But meanwhile the KS16S came out, and I hope to change to this new generation this summer. Also the KS14C/D or the Inmotion V5F+ are great wheels, but I'm sure, others can tell more about them. In short: Wheels, where the rider can easily reach the wheel's limit so that it cuts off, are just not state of the art anymore. For me the wheel is a means of transport like a motorcycle, I rely on it, and definitely expect that it does not blow up or turn itself off under any circumstances.

    Some behind the scenes footage of me using my ACM to shoot parts of a music video. I'll post the footage when the video is out.

    I'm always curious as to how people got started in riding on a single wheeled, electronic balancing device. What got you started in this crazy hobby/sport/activity? For me, I saw a video by Walk Off the Earth where some of the background dancers were riding on mini segway rides. Interestingly enough I think they were Inventist Hovertrax hoverboards. I've always been fascinated by the self-balancing technology ever since the original Segways were invented, but the cost and size was too prohibitive. The Walk Off The Earth video led me to discover Casey Neistat who reviewed the $200 hoverboard thing: This was of course before all the fire scares were reported. I ordered one from AliExpress, and it was a lot of fun. Incredibly nimble and amazing to ride. After buying another hoverboard with larger wheels from AliExpress, I saw a video showing these EUC's which blew my mind. I quickly bought a cheapo generic wheel to try out from AliExpress as it was actually cheaper than the hoverboards I had purchased. I had a heck of a time learning to ride it. It was so difficult to trust the wheel with a slight forward lean that I almost thought I would never be able to ride. After persisting at it, I finally was able to do some rudimentary laps around a basketball court and ended up purchasing a Ninebot One E+ never looking back since. The hoverboards are collecting dust downstairs, but I hope to sell them off. How did you get interested in electric unicycles? What's your story? How did it all begin for you?

    I have been riding my kingsong 14c for a few months and It drove me crazy how tiny the pedals are. Obviously, I am not the only person who thinks this. Used 1/4 inch think redwood planks, VHB mounting tape, gorilla glue tape and covered it all with grip tape. It ride so nicely now. Center of gravity is a little bit high, but its not bad. Ankles do not hurt and its just great. Main piece of wood is 10 inches by 4.5 inches. I also made a video showing it all:

    I first heard/read about the original Segway when George Bush fell off one. I remember being entranced by how futuristic and weird it looked. Seeing it somehow stay up at that riding angle. You'd be surprised how many people have no idea about even the basic concept of gyroscopes. Anyway, I went on holiday to Madrid in 2007 with my then-girlfriend and I booked what was then a brand new concept - the Segway Tour. The guy who ran it was some banker who had quit the City, and bought like 6 of these £5000 machines (They still cost that!). Seems hilarious now, but it was TERRIYFING getting on it for the first time because it was so alien-feeling. We had the best day zooming around the city seeing all the sites in 3 hours. I did so 'well' (my gf was a retard) that our guide at the end used his special key to 'treat me' and unlock the 'high speed' option on my Segway.........*drum roll*........18KPH!!!!!! At the time, this did feel like warp-speed. It was a great holiday but all I could think about on the way home was the Segway. I was a student at the time and obviously could never afford one but I remember thinking to myself, if only someone could take this tech and put it in something smaller and cheaper. Even then though I would never have believed that this could be done into something as small and slick as an euc. Fast forward to two years ago....I'm walking through Wimbledon and some guy comes out of nowhere on what I now know is an Airwheel X3. I was smitten instantly.......

    Marty, that clip is worse than any horror movie, where you know the protagonist is going to suffer something bad, sorry Buddy . Let's get this sorted out!

    It can be speculated, but probably no-one knows for sure. For the KS16S, it does have several merits (or limitations, depending how you look at them, like lower speed and max power ) in the design: -NTC-temperature resistor placed right next to mosfets / heatsink, measures temperature much closer to where the hottest parts (mosfets) are -Lower Rds(on) in a single mosfet than the parallel configuration used in ACMs, also avoids the pitfalls of paralleled mosfets, as low Rds(on) -mosfets do not seem to be available, at least not in TO-220 or TO-247 -packages, for voltages above 75V -Larger mosfet casing (TO-247), can take much more heat and has more surface-area to dissipate it to heatsink -Lower power, the components, wiring and motor need not take as much abuse -Likely more conservative limiting in max currents, probably warns of overtemperature with tilt-back or something (never hit it myself) -BMSs appear to be communicating with the mainboard directly (third wire coming from each battery pack) -Active cooling (fan) that turns on at higher temperatures, although how long it lasts with all the vibration and shocks, no-one knows I haven't opened it up to check the wire gauges, the connectors are MT60's, judging by pictures, the motor cabling coming from the mainboard would appear to be the same as the battery wires (14AWG), but whether there are as thick wires on the actual motor-side, I don't know.. If subjected to a high enough current for high enough time, they will probably also melt at some point, but I'd expect the wheel to warn you far ahead of that, or not even allow as high currents.

    http://vancouversun.com/news/local-news/vancouver-mans-first-ride-on-electric-skateboard-ends-with-600-ticket Same motorcycle cop as harassed me busted this poor guy on a V2 Boosted Board on his way to work. Handed him a $600 fine. Shop that sold it takes NO responsibility for not warning him. How is it NOT entrapment to allow the sale, (with no warning) of a $2,200 item which is then illegal the second he walks out of the store? I have written the author of the piece and sent it to the local sellers, and I emailed LongBoarder labs (who sold it to the victim) to ask if they are going to help us change the law, or just take the money (diplomatically though of course!) and continue to ignore their customers paying a heavy price due to not knowing. Vancouver - Home of the combustion engine and jack-booted law to keep it that way! Don't believe the "green" crap, it's all lies in this city. I'll be next, eventually this cop WILL see me again

    The end of yesterday's ride through Ohiopyle, Pennsylvania. We rode a few miles of the Great Allegheny Passage (GAP) rail trail, then explored the town and waterfalls. The GAP trail is hard packed dirt and easy riding, at least in this area. The only minor issue was a few muddy spots since it has been raining a lot lately. With a connection to the C&O Canal Towpath you can ride from Pittsburgh to Washington DC. That would be an epic multi-day ride with camping along the way. This trail will always be remembered by me as the first time I successfully rode on one foot!

    My interest began shortly after watching Mike Tyson fall off his hoverboard. It was a news sensation! A small two wheeled gyroscopic conveyance dumping Iron Mike on his ass! The rest is history. I was hooked riding the boards and then transitioned to EUCs shortly there after. Best move I ever made ( except for marrying my wife and having kids)! This short journey has introduced me to this wonderful forum and all of the camaraderie that has followed. Thanks!

    So I was in South Korea 2 weeks ago on some personal / vacation stuff, and made it a point to try and visit every brick & mortar EUC shop possible while there (since the US has no such thing). One of my stops was GEVKorea, located in Busan (2nd largest city in South Korea), of GEVKorea spec'd ACM16+ fame. My badgering of the initial salesperson with various questions led me to speak with someone whom I believe to be a manager. As we talked, and he realized I was more EUC-head than casual customer (and that I was from far away), he revealed to me the existence of a GEVKorea spec'd MSuperV3 TURBO prototype (I am posting this with his permission). Basically, this GEVKorea MSuperV3 TURBO prototype addresses the following: hardest response out of any Gotway wheel out, much harder response than a stock MSuperV3S+ (which is the softest out of the current Gotway line). as a result of the harder response, acceleration from rest is faster (more torque going uphill as well), and braking is harder / faster. like the GEVKorea ACM16+, connectors and cabling is addressed, and a fan that is larger than the ACM16+ fan is implemented. The manager expressed that he was not certain yet whether GEVKorea would release this TURBO version though. Having tried this prototype myself, if this version ever reaches production where I'm able to purchase, I'm totally getting one! The manager recommended that since, economically, GEVKorea couldn't sell/ship abroad, to try Gotway direct in procuring such an MSuperV3 configuration. Any chance on an eWheels MSuperV3 TURBO @Jason McNeil? *hint* *hint* *wink* *wink* (also, for those wondering, some of the customizations in the pics were modded by GEVKorea themselves, like the USB port being replaced by a second power button that turns on an in-wheel LED light array) Also while there, I tried out the infamous ACM16+. Unfortunately, I have no frame of reference to the stock ACM's, as this was the first ACM I've ever been on, but the response was pretty hard as well (not as hard as the MSV3 TURBO prototype).

    Our KS18S/KS16S, ACMS+ & V8s all arrive at the same time, late June/first week of July delivery. This gives an idea of what the process & lead-times are for getting product shipped to the US:

    I fabricated a custom silicone cover for my wife's new KingSong 14C. This method can be used for any brand EUC. Materials: 1) Duraflex Silicone Liner available at Guardmfg.com. There us another brand called Seaflex that is available through pelsupply.com ($150 per sheet- 32"x 48") You can cover 2 average sized wheels using 1 one sheet. 2) Stoner Silicone Mold Release (any mold release such as Pam will work) 3) Large metal cookie sheet to hold the material in the oven. 4) 2 sets of Gloves The dimensions of silicone sheet I used for the KS 14 was 36cm x 58cm. Thickness of the sheet was 3mm. The material comes in different thicknesses but this size seems to work best. Do The Following Procedures When Your Wife Is Not Home! 1)Heat the oven between 127-149 degrees C. 2) Spray both the large cookie sheet and your wheel's plastic surface with the release agent. 3) Place the silicone sheet on the surface of your cookie sheet and put in the oven. Check the material every few minutes for flexibility. Advice: Test a small piece of the material first. 4) This step is a 2 person job! Wear Gloves! Remove the silicone sheet from the oven and drap it over your wheel while it is lying on one side. Mold the material gently around the contours of the wheels's plastic surface. 5) Let the material cool for 30 minutes, remove it off of wheel and then trim the edges with scissors. I use a grease pencil to mark my trim lines especially around any switches or head lights. 6) Place the trimmed silicone shell back on your wheel, turn the wheel over onto the opposite side and repeat the same process. *Be sure to spray the edges of your first silicone cover to prevent it from sticking to the second sheet! 7) When both covers are cooled ( approximately 30 minutes) perform your final trims. Some scissors work better that others when trying to make tight cuts. You will just need to experiment. 8) For an optimal finish use a Dremal tool or other type of grinder with a smooth grit to smooth the edges of the silicone. I will be completing the protective shell including the final grinding and riveting the shells together shortly. Good luck!
