  1. I have a Freshly rebuilt 820wh 67V ACM. Just put together today . New shell , panels and pcb. ~600mi on motor but gone over with a fine tooth comb and this thing is in peak condition. Shims taken off and inspected last night . They look like new . The wheel itself looks like new . Well..I didnt replace the pedals . They have typical wear but that’s it . Everything else is faultless. Updated the price . I did the math a bit wrong lol Asking $695 1-67v ACM 820wh 1-Standard GW charger 1-Spare PCB (has a small divot in plastic over one mosfet but have been told that it’s fine . Replaced for peace of mind but probably didn’t need to 2-spare side panels (the originals, but still in great shape really didn’t need to replace them either ) 1-way shipping to your door .

    EUCs in Japan

    Hi there, I read various questions on how EUCs are spreading in Japan. So I decided to share some pictures and videos from our group here in the Kansai area. Please 😊 enjoy! https://photos.app.goo.gl/otwk8fFTsSQbnyM43

    ACM board help

    So , as you all know I’ve had issues with my ACM . @Rehab1 was nice enough to send me a brand new pcb but neither of us thought about the fact that my wheel is 67v and the pcb is for 84v. So my question is, is there anyway to have the firmware for 67v loaded on this board ? Or is there anything else I might be able to do this is a brand new never installed pcb ? @Marty Backe, @Jason McNeil, @KingSong69, @Smoother...any ideas guys ? Maybe somebody has a 67v to trade for an 84v ? Otherwise I guess I’ll send it back to @Rehab1.

    Gotway ACM axle shims

    So after replacing the xt60’s on my ACM I’ve put about 60 miles on it . I’ve noticed a fair amount of back and forth play in the wheel while riding and when I just rock it back and forth while powered on. It feels as if the shell itself is moving . I can hear the plastic creak as it moves fore and aft . The nuts are right and so are the screws holding the shell to the footplate “bars?” So I’m assuming it’s a shim issue . Doesn’t seem like I can purchase them anywhere. anyone have experience finding them ?

    How hard can I push my ACM?

    Just received my Used ACM . It’s the 820wh 67v version . V1 I believe but with the v2 (12 mosfet) board installed . It starts to show overspeed warning at 30kph on the app. I’ve turned off the 2nd alarm and set tilt back at 40kph . I’m just hesitant to actually push it that far for fear of failure . Thoughts ??

    ACM back and forth play.

    Noticed tonight that my ACM (new to me as of today ) has slight back and forth “play” when standing still. Could this be loose axel nuts ? The wheel has flywheel keys installed to keep them from loosening. So not sure what’s going on .

    Gotway ACM issue...

    I am currently nursing a scratched ACM and a sore shin! TWICE (actually THREE times) now in less than a week my ACM has just dropped on me! The first (actually the second) time I came out of a shop, turned on my ACM and got on leaning against a wall while I got my feet comfy on the pedals. As I went to lean to set off - gently not over lean/ harsh - it seemed like the ACM flipped on me. I was left standing on the ground with a sore right shin where the ACM caught it somehow and the ACM looked to have smoke coming from it. It could have just been dust though. I picked it up, turned it off then back on, got on and set off normally. It has worked fine since until this morning! I went to set off for work, I set the ACM down, turned it on, pulled down the pedals and before I got on and moved the ACM forward and backward to make sure the wheel moved ok (I've been doing this since the first incident) then got on while holding my fence as I got my feet comfy. As I leaned forward slightly to set off the ACM just dropped on me as if it wasn't even turned on. once again it somehow caught my right shin. once again I picked it up, turned it off then on again, got on and set off normally. I am wondering if it just dropped on me first time as I wasn't really paying attention but this morning I was because I have been cautious since the first incident. Just before my ACM was due for dispatch it was said that peoples ACM's were frying due to an overcurrent when the ACM tried to go over a bump or out of a ditch at low speed. Apparently mine was kept back to receive the "fix" but as I have since found out I didn't receive the new board I am wondering if the fix is what is causing the ACM to drop when trying to set off slowly? Whatever the reason I am not happy. Twice in one week and a scratched ACM and shin, Edit - I've just realised this has actually happened to me THREE times in less than a week. The first time was the day before the second time. I was riding along the canal and was stopped by a couple asking me questions. For some reason I turned the ACM off while chatting and then turned it back on and went to ride off while they were watching and it just dropped which made me embarrassed because i never did that on my Ninebot and it was my first drop with my nice new ACM. Initially I thought it was because the ground was uneven and I didn't balance correctly but thinking about it I didn't have chance to move because it just dropped as I got on to set off.
  8. I think eventually I’ll buy a Monster. It may be when a version 2 comes out... not sure. One thing that bothers me about it is how fragile the shell is when taken a minor spill because of its weight. Do you think anything could be sprayed onto the shell to make it more durable. I was thinking about some truck bed liner spray or some kind of rubberized spray that may give it more durability. Just curious if anyone gave a DIY solution some thought. Since Gotway seems to have removed the spin out off destruction when the wheels go on their side. This might help with future Monster shell damage.

    16" Tire Width Options

    Curious to see the favorite tire size preference for the favorite 16" EUC category....
  10. Hey everyone, The time has come. I have now put 350 miles on my MCM4 and have decided to upgrade to a newer better faster bigger longer lasting wheel. So here goes.................... First things first - I know some of these wheels have suffered from the Gotway Oscillation issue. This wheel will be coming from Jason. Have all these concerns for the most part been resolved? Now that that's out of the way here goes: I have heard much praise from everyone regarding the ACM, I see lots of people reporting that it is their favorite wheel. I have actually ridden the ACM a couple of weeks ago during a group ride. I can say with my limited time with it it was very enjoyable and felt very stable and fast compared to the MCM4. I have never ridden the MSuper. Here are my questions: Will there be a noticeable stability difference from the MSuper to the ACM? In my area there are many uneven roads and potholes so the 18" wheel could be a big help. My current size/weight is 6'1" 220 lbs. I am on the heavier side for EUC riders. Bigger wheel may be better for me since I am on the heavier side. From others experiences what are the top speeds of both all things being equal? I'm not looking to max it out all the time and risk my safety but being able to ride at a sustained speed around 15-20 mph would be preferable. Currently my MCM tops out at 17 mph due to my size and weight and yells at me constantly. I also have found it a lot of fun taking my EUC on trails intended for mountain bikes. I would think the 18" wheel would handle the terrain better, however, the higher torque from the ACM might be nice as well. I also enjoy long trips. Either choice would be the 1600 Wh variant. The minor difference in price would not be a deciding factor. Lastly, I am going to need something that lasts. I'll be dropping close to $2000 on this wheel and I will need it to last me quite a while. Thanks everyone for any input you can provide.

    Gotway ACM Trolley Handle - Installed

    Thought I would share my handle install with the forum in case it is helpful. Bought it on eBay and can be mounted to front or the rear. I chose the rear just for ergonomics/appearance. Works/fits fine with the power port. Makes it also easy to wheel around if powered up, just by applying slight pressure front/back. Basically drives itself, as you'd expect. For the install, you will need to bend the steel plate that goes over the lower part of the wheel, as shown. It comes as a 100% straight piece. With this slight angle at center, it creates a flush fit. To install, you'll need to pre-drill the holes at top and bottom. I do like that this steel plate makes the junction of the two shell pieces stronger when attached. Note also that the top will also require pre-drilling with the same bit to be able to put the screw through it - it is hard plastic and was not fully pre-drilled. It was quick and easy to install. And so far, so good. The looks are certainly cleaner without it, but for function in commuting to/from platforms, very short distances, it is worth the tradeoff - the ACM is a ton of bricks to lug around. Hopefully this is of use if you're considering it.
  12. Good afternoon everyone, I purchased an ACM 1300 from Gotway America a couple of weeks ago. Due to a leg injury I did not unbox it until this morning. First impressions out of the box were not all positive. The seams for the case on both sides were less than perfect. I was ok with this seeing as how I know that Gotways QC is not top notch. Not happy mind you after spending more than 1k on it but I kinda expected something like that. Upon riding it for the first time my initial reaction was good. It felt smooth, was very maneuverable and acceleration and braking were very smooth. After riding for a half mile or so I began to hear a creaking/grinding/chirping noise coming from the ACM at about 5-10 mph, initially I though I had picked up some debris and it was rattling around inside the wheel, could not find any debris present. I figured I give it some time and maybe it would go away. Not the case, I went 13km and decided it was time to hang it up and figure out what was happening. I cannot get the sound to reoccur from a standstill, nor does it happen at higher speeds. It appears to only be in that sweet spot of 5-10 mph. I'm not sure what could be causing it. I have contacted the seller to ask if he wants me to open it or send it back. It's brand new perfect condition been dropped 0 times. Anyone experience anything like this? Not a super happy camper, we will see what happens .

    Anybody wanna trade

    Look like most people prefer the msuper pedals based on what I have read on the forum, but me personally I prefer the ACM pedals, I have a pair of msuper pedals that's about 5 months old, has some scratches but all the grip is still there, if anyone wanna trade me ACM pedals for some msuper's let me know I would really appreciate it. I live in Sarasota Florida

    ACM 16 pedal behaviour

    Hi! Received my ACM16 820wh today. As I rode, I noticed some strange behaviours on my pedals, compared to my Ninebot S2. When I turn, especially at low speeds and sharper turns, the pedals turn forward to the point where I think I'm gonna fall off forwards. And when I ride fast (30km/h+), even without tiltback activated, the pedals lean back so it's uncomfortable for my feet and sometimes I fear slipping off backwards. I would like the pedals to remain as flat as possible during all aspects of my riding. I want to know if anyone else is experiencing things like this, or they did and just adjusted themselves, or if there is a way to update the machine somehow to amend this behaviour. I don't think a calibration via the app will do it as it would exacerbate the issues one way or the other. Cheers!
  16. Location: Arizona Occupation: Student Weight: 215 Height: 6'3 In the last 3 years I have become entranced by Last Mile vehicles. The concept seems like the future of personal transportation which is a game changer in a place where everyone hates walking outside in any manner that isn't exercise or trying to get inside. I have had several phases in this Last Mile Hysteria I've had. First electric longboards. Bought a Metroboard Stealth for $1400. Fell off a Metroboard Stealth. Now Selling the Metroboard Stealth (or keeping it for friend riding). Should have known since last time I went snowboarding I separated my shoulder. Sounds like I'm not athletic but I've played sports my whole life. Boards just don't belong under me apparently. Next was electric scooters. Seemed like a great balance between something portable, fast, and safe. Lots of research later I came to the conclusion that with my size I should look elsewhere. Also too expensive for the ones that I would actually purchase. Afterwards was the Onewheel. Not quite like any other device out there but it opened up the avenue of offroading with these vehicles. Awesome revelation and makes for a far more versatile device. Too expensive. Now here we are at the current final frontier in my passion. Electric unicycles. They are frankly far more advanced than I was expecting when I started looking at them. 4 Deciding Factors 1. I want something I can carry into places without a whole lot of hoopla just trying to find somewhere to put it. 2. Something manageable for city maneuvering (although I fully plan to use it recreationally and offroad at times) 3. Something that fits my size and weight effectively. 4. Price. Need to stay sub $900. Every type of device has it's pros and cons especially for my size. Longboards suit my size but not my riding style. Electric scooters really seemed great but not suited for my size. The Onewheel became exactly what I was looking to try with the version 2 coming out this year. But it is a 2 month backorder from the company and the ones on Ebay are selling above retail of $1400. Also decided I was going to drop to a lower price range. Frankly the only reason I started looking at EUC's (feeling cool getting the lingo like a boss) is because I saw a few in my searches for other things. Once I found out they can go offroad similar to a Onewheel and actually go faster I was hooked. A single wheel seems to have the torque and motor qualities to be effective for my size. I have been doing a fair bit of gandering (not a word) and the other deciding factor are some deals available to me. Deal 1: ACM V2 67V 820wh w/78 miles $600 Deal 2: ACM V2 67V 680wh NEW $675 Deal 3: ACM V2 84V 1300wh NEW $900 Deal 4: MCM4 HS 520wh Few Months of Miles $500 Anyone care to rank the quality of those deals? Also any advice on what I should be looking for due to my deciding factors? This would also be my first wheel and I have never ridden one but I think the riding style is conducive to my physical ability.

    ACM vs Luffy Vibration Test

    I purchased an app for my IPhone 7 that is a 3 channel vibration spectrum analyzer. It uses the internal accelerometer and gyroscope of the phone to analyze vibratory and rotational motions. You simply place the IPhone so it is firmly attached to the object you want to analyze, hit the sample button and the vibratory readings begin. I only used one channel to measure the vertical (+Y) coordinates during my initial test run. I attached the phone to both my Luffy and ACM 1600 using Velcro but a more stable mounting platform is in the works. Below are 2 sample graphs depicting what data can be produced when using all 3 channels of the app. So I went for a little ride on the ACM and Luffy around a bumpy piece of property next to my facility to see if I could obtain any quantifiable data. The data may be skewed a bit due to the Velcro method I used to attach the phone to both wheels but it was a fun experiment and only cost $4.99. Below are 2 more graphs depicting the Y coordinate data I obtained from each ride. Combining X, Y and Z data will be performed in future tests. You can see the very small vibration levels at the beginning and end of each graph ( Luffy had an issue) representing the smooth parking lot where I entered and exited the course. Unfortunately Luffy could not make it over the parking lot bump ( also might be my skill level) at the end of the course and I fell off which created an interesting peak. In the middle of the graph there is a good representation of the various bumps I encountered throughout the simple course. Now for a good laugh!
  18. First: Changed the headlight SMD with about 80 Lumen(right) to 300 Lumen(left) output. The new one is the same like the SMD from Cateye Volt300. Forgot to make pictures before and after. Unfortunately... But it's really bright right now Now I just hope the heat dissipation works well enough Second: Add some SMD to the backlight. Second picture is the original LED strip. Third pic with the modification.

    Monster & ACM updates...

    Hi all. Just an update on where I am with my recovery, Monster and ACM. Sorry if I waffle on. Recovery - My eye is still very sensitive and I'm still missing half an eyebrow though the battle scar is pretty impressive. My chest seems to have stopped hurting so much when using my left arm/moving about/not comfortable. My right wrist was feeling OK until my eldest daughter went to, jokingly, knee me in the leg earlier when we were being silly and my natural reflex was to block her... OUCH! My right arm and elbow had been quite good until I stupidly decided to unbox my Monster again, finally, and open my ACM to see what's up.I still can't straighten my arm and both my wrist and elbow click/crack when I move my hand/arm about. I'm hoping I haven't done anything to my neck as near where I had my op and where the problem area is has been a bit more painful than usual and my neck cracks and crunches as I turn my head which I think it did before the accident but not as much. Monster - It's been sat, boxed up, since Ian sent it back to me just as I had the accident. When I turned it on it started to roll backwards slightly. I realise this is likely due to the weight of the tow batteries at the back. When I put it up on blocks to see if it needed calibrating possibly it span up to full speed even though straight - I forgot to note which way the wheel span. Maybe it needed calibration after moving the parts from one shell to another? or maybe it was like this previously and I didn't notice? Anyway after a few attempts the Gotway app finally did it. It's currently on charge and I'm going to be going slowly on it initially to make sure all's well. Ian says the wiring is fine and everything connected/fitted right but take it easy just in case. Hopefully all is good and all three batteries work fine. I'll know more when I am able to get out and test the range after this charge. ACM - I shouldn't have, because it hurt my wrist and arm, but I couldn't wait any longer to take a look inside. For some reason the pedal isn't for coming off, even though I've taken them off previously, so I struggled to get the side panel off then back on after checking. It looks like the axle has snapped? The nut doesn't seem loose but the axle wobbles quite easily. I can't see any board damage so think it needs a new motor all together? Speedyfeet don't have stock of the motor in, currently, but I've asked Ian for a quote on him replacing it for me so I know it's done right. I am weary about self repairs after the Monster arcing incident and the ACM already throwing me off due to a fault. I'd be happier knowing it was done properly by someone with plenty of experience. I might also email Graham Goodbarn of Yorkshire Airwheels, where I purchased it, in case he is confident enough to do the repair, as he was fantastic with my early ACM issues and offered to do the board change previously but looking at the website I don't think he has stock either. To be very honest, after the accident and with the time that has past since, I am getting more and more anxious about riding again. Especially the bigger and heavier Monster. I am going to go look for some protective gear this week, ready for going back to work next week (if I've recovered enough to ride) as I want to get an idea of the sizes I need before ordering some decent stuff online. Ian said he's getting some D30 gear around Christmas and I think that's the way I want to go. My only awkward decision is the helmet. With how I fell from the ACM, and seeing the video of the girl falling from a standard unicycle and hearing the sound her face made, I know a full face is likely the best idea but mostly when going to and from work I ride at a quite sedate pace along the pavements - if someone was to see me on the pavement with a full face helmet it may draw more negative attention - especially from police? My longer rides out with my girls, around the lake and along the canal would probably be ok with the full face. In the two years of riding without a serious incident I was confident I knew what I and my wheels were capable of and felt secure and safe BUT after the ACM fault and reading about peoples other recent Gotway incidents with the newer models I don't feel safe now BUT it's my mobility seeing as I can't walk or ride a bicycle due to my problems so I need to get my confidence back. Sorry for the waffle, thanks for reading and any advice that may follow

    Gotway ACM 820wh / Some Questions!

    Hello folks, I've been riding my Inmotion V5F+ for a about year now with total mileage approximately 5100km. Recently, I felt like I got bored of this wheel. To be more concrete, the speed and range doesn't satisfy me anymore. I feel like I want more. So I've been looking for a replacement and thought about Gotway ACM 820wh. Would be cool if you could answer my questions! 1) How far can you get with 820wh version? Will it give a significant increase in range comparing to Inmotion V5F+ (480wh). 2) How nimble is the ACM? Again, comparing to V5F+. 3) What is the maximum safe-cruising speed that can be achieved? On my V5F+ I can hit 25-27 km/h. 4) Is the speed increase that noticeable between 25 km/h and 35-37 km/h? How does it really feel? 5) Do you feel Gotway ACM the same way as Inmotion or there's a new learning curve involved? As for now, that's all =)
  22. After having great experience with MCM4 HB 680 , Just purchased ACM v3 s+ 1600 and A monster 1600 which was unfortunately departed gotway in mid may so It probably has defected PCB. I am in contact with JaneMO (who is very nice and responsive to me all the time) and she confrimed that she will send me a replacement board for the ACM but it will be a MSUPER v3 84volt PCB, I wonder if this will be a problem to use on ACM. I will be glad if you experts can comment regarding this. Monster confirmed to have safe PCB and I understand it is 100 volts. Furthermore, I hope to modify these wheels once they arrive, and I would like to keep you updated as I really enjoy reading your inputs and expereinces. ı really appreciate any suggestions for below or in addition. Possible mods Im thinking: -Mud shield -Digitial output volt meter -Internal thermo meter and blue tooth speaker ( no space on acm) -replacing lights with high lumen ones -PCB Fan if missing on ACM / there is 2 on monster. -Stabiling axis nuts and re organize cabling with flame proof covers -Damage Protection for the wheel (any innovative ideas?) At last, I had a chance to visit both gotway and kingsong in Shenzhen, I agree with most of you regarding quality differences etc, but also accept that we are in love/hate relationship with Gotway. I think they can be better If directed more via end users like us. I hope to keep you updated regarding my wheels here. I would like to also add that both Jane Mo from Gotway and Tİna from Kingsong are extremely nice well english spoken and responsive people. Here's some of the pictures from our trip in 2016

    A switch to turn off the alarm

    I installed this switch so i can turn off the alarm. It's so i dont have to hear the alarm all the way back home from somewhere when my battery is low. Once ive heard the alarm i know to take is slow and not push it.
