  2. please skip to bottom for potential cause if post is too long for you I. Intro Hi all, thank you creating this community. I'm excited to join you, despite having to ask for EUC help with my very first post here. Hopefully my story can help other people or serve as a cautionary tale for anyone who thinks cutoffs only happen because of speed or overleaning. I was lucky with my fall but it could've been way worse. II. Unexpected first cutoff and fall ~25km/h I bought my MCM4 (HS 680wh) a month and a half ago second hand ( ~970km) and it served me very well for 200km, until it suddenly cut off without warning nor tilt-back while going around 25km/h. Having read a lot of posts here, I assumed it was user error, maybe an uneven spot on the bike lane, maybe 80% battery wasn't enough for my speed. I was just happy I had a helmet and wrist-guards on, and managed to do a roll, so I only ended up with a slightly sprained ankle and a bit of road rash on my lower back. Until then I had ridden 7kms on that journey and had a pause of 2 hours before heading back and having a cutoff on the second minute of riding. The bike lane it happened on was separate from the road and despite that my EUC went on the road during rush hour. Thankfully there was a traffic jam and also it somehow managed to miss all the nearby cars. Yet, I couldn't help but think about the unsecured bike lanes I rode on shortly earlier that day and what could've happened at the wrong time and place - I'd rather stick to sidewalks and slowing down for curbs and pedestrians. I carefully rode the remaining 7kms home without any further issues. III. Weird low-speed tilt-back and cutoffs The following days I had short trips and casually rode around to see if I can trust my EUC after my first no-warning cut-off. Everything seemed normal for a week and just as I had written it off as user error I got some tilt-back while going around 5km/h. It was so unexpected that I thought I'm imagining things but I carefully finished my journey. Yet on the way back, an hour later, after 3 minutes of normal riding it happened again around 10km/h, this time leading to a cut-off after I stepped off, followed by 3 beeps similar to when it has fallen to one side and a 4th beep when it resets. I turned it off for a few seconds and back on and carefully rode home. I think it happened a couple more times for the remaining 2-3kms The next day everything seemed in order, I spent a good hour or so riding back and forth without issue ... until I went out later the same day. I rode 1km and again got the low-speed tilt-back and unstable floaty balancing. Only this time it kept losing it's balance, cutting off and resetting, even without me stepping on it, just by rocking it back and forth with my hand, in fact I couldn't push it with the trolley without it failing to balance. After I left it for a couple of hours I could at least push it with the trolley so I started wondering if it's something to do with the battery, despite it being around 70% Today I decided to go out so I can record videos of it failing, as well as to check current, etc in the EUC World app. I rode cautiously while recording video for 10 minutes without it failing. I turned it off for 5 minutes and tried again and this time it did it immediately. I went home, charged it to 100%, went out again and repeated the experiment, with it initially working OK but then cutting off in less than 5 minutes of slow riding. IV. This doesn't look right?? Since it started consistently failing despite the low speeds and fully-charged battery, I decided to open it up and look for some clues, even though I'm not knowledgeable in electronics. I got the first cover off and immediately saw this. I have no idea which connector is responsible for what, but it looks this one has come undone despite the glue/paste it was covered in. I would be very grateful for some information and advice: Should I just plug it in? Should the batteries be disconnected first? Do I have to unscrew the whole board? Do I have to watch out for something else? V. Edit/Update OK, so turns out this connector is for the USB and should be irrelevant. Still looking for a solution. I haven't checked out the capacitors/etc yet but will look into that. No obvious issues with capacitors, mosfets or wires that I can see, at least.
  3. The manual makes a point about a specific order of connections when charging a wheel. I have MCM4 HS but I suppose most Gotways should be nearly the same in this regard. The order is: To charge: * Connect the three-prong connector to the wheel * Plug the charger to the wall socket After having finished charging: * Disconnect the three prong from the wheel * Unplug the charger from the wall socket Is this the ritual other Gotway shamans observe? I ask because even though I'm ready to accept this nonsense for the sake of preservation of an expensive piece of equipment, I don't like how too much seems to be dependent on a completely arbitrary order that's very easy to mess up. What makes me especially worried: * When I start charging and connect the three-prong connector, there are sparks flying. I'm having a hard time accepting this as normal. * Until I plug the charger in the wall, its LED shows up as green. It's not a problem per se, but I think it's an indicator of a bad electric design. So, should I worry more than usual about this or is this just how those things are?
  4. I recently bought a Gotway MCM4 340wh and it doesn't seem to charge above 65%-70% (~62.25V) according to the android app. Even if I leave the charger that came with it plugged in for hours, it won't raise above this. The light on the charger stays green, so it won't charge further. Here's what the LEDs look like on the wheel when it is at "full" charge: I'm not sure if there should be more green lights on full charge? After riding it for about 8km the battery shows 30% charge left (two red leds) and it also frequently starts to beep when going uphill (voltage drops too low?) so I'm not getting anywhere near the advertised 30km+ range. I opened the wheel and checked the battery and it says 340wh on the sticker on it. Any idea what is wrong with the wheel and can I somehow fix it?
  5. Hi! I'm new to this forum and also to the unicycle world. I've never tried a unicycle before, but I've considered buying my first one since im going to use it as a regular vehicle instead of a scooter/bus/tram etc... I just don't know where to start. I found a swedish shop called greenridestore.com but it is SCAM. I bought a wheel from there but got no response (I was supposed to pay one month later so I was lucky to not pay immediately, so I did not loose any money. Now I want to be "safe" this time buying from ebay or ali express or something since I don't know about any reseller in Sweden. My biggest priority is that it need to be a long distance one for around $1000, and I found the MCM4 680wh to be a suitable one since it goes 60-70km on one charge. Do you have any other recommendation for me? Otherwise I want to have a suggestion of a seller that is trustworthy. Someone people use to deal with etc. Could you help me with that?
  6. At first I was thinking of buying an Airwheel duo to the January Sale where for example the Q3 is 50% off at TheAirwheel.com. But now I´m thinking of getting a Gotway since there is a lot of positive feedback for it. Am I wrong or is it really better please tell me I´m not very experienced Unicycle or whatever you call it user but please dont come up wiht comments that are lead by my not existing experience and only give me some in that way neutral feedback. Now I´m considering buying a Gotway MCM4 thru this link http://www.aliexpress.com/store/product/Reserve-Gotway-MCM4-130wh-260wh-340wh-520WH-680WH-electric-unicycle-one-wheel-scooter-800W-motor-max/1908673_32468490098.html . But now I´ve come to the question where I would really like to know what battery capacity is really worth it and how far i would come with the 260wh and the 340wh option both ordinary and high speed version. And if I ride at about 20km/h with both wheels will there be a difference in distance? Is there a different motor or is it just a different speed lock because on the alibaba page it says that the maximum climbing of the ordinary version of the MCM4 is 35° and of the MCM4 HS version is 28°. I´m just asking because for me it doesnt make sense to buy the none HS version because they are completly the same units but with having a different speed limitation. Has anyone made experience with one of these? I would really apprechiate any answer. Chiiter PS: Sorry for my bad english; if you dont understand something please tell me and I will try my best explaining it. Edit: Does anyone know how it is with the german customs/duty if I order one of these?
  7. By blackwidows January 24 2017 After 18 months and 5000 km with my faithful Mcm I cracked for a Tesla 1020 and after 250 km here is my opinion.I specify that I ride especially in Paris and Brussels, that I mainly use bike paths and roadway; the sidewalk when I have no choice but at a very moderate pace. I use my wheel daily with train trips. The MCM 4, if I have to compare to a car will be an old mini Cooper S Potato side : Vive at startup but very quickly 2 beeps which calms and forces to listen to his wheel, not to mention that is not discreet. Side comfort: It is not the dream, one is much shaken and the inflation is important in its behavior but with a flexible conduct one supports even the pavements. My wheel never fired me despite quick passages on big holes. Urban side: very convenient with a trolley, it goes everywhere even in the instructions of Brico for example. The position of the trolley to ask his bag or basket when shopping. The wheel is not always stable when it is lit against a wall, it tends to move. Side autonomy with 640 w and HS model can be done 35 km to 20 average after performance deteriorate. After 5000 km I did not notice any noticeable drop in battery life. This wheel is bright and almost fast enough for my use but when you drop the comfort of a tesla return on 14 inch scary. After a test of a Msuper 3 for 24 hours and a tesla I cracked for the tesla 1020 Tesla for the car the Tesla S seems perfect After 250 km and a bowl (it makes me humble), I was able to test the tesla mainly urban use. The weather conditions for 15 days have moderated my desire for great walks and I have not done more than 40 km days. it's the world of silence, no more beeps in comfort. Potato side: With tilback settings to 42 km, that I am not sure of having reached, It seems not to advance but it accelerates more than the Mcm but in a linear way and we always have the impression that there is still power in reserve. Comfort side: This wheel is really stable, holes and other defects of the road go by alone, my average speed has almost doubled on some courses with a max speed barely higher.on the impression of rolling on a rail. Slow speed steering is almost as easy as with a 14 inch. The pads located just below the knees are quite unpleasant at first, especially when stopped, but I got used to it. Urban side : The position of the trolley is quite surprising but allows easy control in crowded station platforms.Putting your bag on the wheel is less easy than on the Mcm and the trolley is a bit short. The wheel is very stable on, it can be easily placed on the trolley. The extra 4 kg did not change anything in my use. I did not drive enough to talk about autonomy because I never made more than 40 km before reloading. Negative points the front lighting is unusable in town especially with my calibration setting a little back when the red there is none, which is a serious handicap in the event of discussion with the police. Trolley too short Gotway application Conclusion I still love my Mcm that I continue to take for my shopping but the Tesla is much more reassuring for me, we can hold a speed of 30/35 in comfort when we are on the road and as in half of Paris and Paris. Brussels are zones 30, one is in the traffic without being doubled by excited ones. The Tesla with legal lighting and legislation Bike seems to me to be the ideal means of transport for the city.

  8. Hi, thank you for the great forum. I would like to start with EUC so I have not much knowledge. I want to buy an EUC but have not decided yet. I would be thankful for help! I live in a city (and especially my street) which is quite steep so some power is needed. I do not intend to use it regularly for my commute but more for fun or for some travels with trains etc. Therefore range is not a big issue. I like speed. I am not squeamish when it comes to carrying weight, but as mentioned before, I will use it for public transport so a medium weight would be nice. I do not care much about the design. I care for durability. I do not need a fancy app but setting a speed limit for the beginning which can be removed when I think it is the right time is good. I do not mind buying a used one, but my impression was that the price difference is small. So I thought about parameters like this: 500W/15km/28km/h/12kg I do not want to invest a lot and would like to invest below 400€, nevertheless, I do not want to invest 350€ for an EUC which I will consider too weak after a few weeks. I considered the Ninebot S2 which I can get for about 330€ with warranty I considered the Gotaway MCM3 (130WH) for 313€ without warranty I considered the Gotaway MCM3 (170WH) for 360€ without warranty I considered the Gotaway MCM4 (130WH) for 463€ without warranty I considered this one (https://www.aliexpress.com/item/2016-New-Fashion-style-Powered-Bluetooth-unicycle-1600W-self-balancing-car-smart-car-single-wheel-thinking/32738452250.html) for 284€ but when I asked about more details the seller told me it was out of stock. I considered the IPS ZERO (240WH) for 421€ without warranty . If you have other recommendations or better prices (for Germany) I would be thankful. Also if you think my parameters are bullshit feel free to tell me. Thank you very much!
  9. Hello again! It's been a while since I've been on the forums. I'm looking to upgrade from my Ninebot One C+ and IPS Zero 240Wh. I'm living near my college campus, looking to save money on gas, time with parking, and have fun. However, I don't trust my Zero commuting off campus (or at higher speeds) and the Ninebot is too slow to be safe in the bike lane. I've been looking at the Gotway MCM4 for a while now but it seems like no one's agreed on how safe it is. What do you guys know about it? HS vs HT? The Inmotion V8 looks amazing and really reliable, but if I can go faster and go further for less money... Thanks! Also: the MSuper V2 HS is about the same price as the Inmotion V8. Obviously difficult to compare but I'd much rather have an over-capable wheel than an under-capable one.
  10. Hey, i am just totally confused about the alarm setting of my Gotway MCM4. In the app there are 3 options for speed alarms: - close first alarm - close second alarm - open alarm At the beginning, there was an alarm at 18km/h, if I push "close first alarm" the alarm starts at 24km/h. But when i push on "close second alarm" the alarm at 24km/h is still there. I already tried different combinations of the 3 options, to get rid of the second alarm but it does not work. Someone of you already worked out, how to get rid of all the alarms on mcm4? What i want to get, is no alarm and tiltback at 24km/h but it is impossible with my app!?
