  1. Holy shnikeys! https://youtu.be/xYNIs5cld5I
  2. Seeing reports of the Gotway RS, an MSX form factor with the new hollow motor rated at 2600w. A since-deleted post with a spec sheet listed two editions, torgue and speed, with lift speed specs at 97 kph for the speed edition and 79 for the torque version. Can anyone confirm this as an actual release? I'm liking the specs but not liking the holdover MSX form factor, which has proven to be very fragile especially in crashes at any sort of speed. I also find it interesting that Gotway included "100V" in the model name (RS 19" 100V)...Does that mean there will be an 84V version of this wheel? Or, maybe something higher than 100V?
  3. Thanks to Gotway, they allowed me to share it all with the community. need a part repaired or modded? just edit and print! This is all the files, Shell, panels,front,back,top panels.. Enjoy https://www.thingiverse.com/thing:3519413
  4. Has anyone heard of this variant? Is it a new official Gotway or an unofficial mod? Either way, the specs look good! https://eucservice.com/en/gotway-msuper-x/72-gotway-msuper-pro-1800wh-100v-21700-new-cells.html New Msuper Pro Specifications: 1-19inch skid resistance Tire 2-Double T6 head light , Intelligent brightness 3-5w strong heat sink fan 4-35w BT music 5-2500w motor 6-100v 1800wh 21700battery 7-Lift up switch
  5. Ever cutout on a Gotway wheel because you couldn't hear the beeps? It's not uncommon to hear from people who love to ride fast. I've been struggling with the beeper placement ever since I purchased a Gotway. After many months and a cutout, I finally came up with the FlyBeeper. This mod positions the beeper straight up unobstructed by anything on your wheel. It's been tested and works great. For those wanting to do this on your own, the first 10 or so minutes are the steps necessary to split the shell and install it. I'm not positive if the stock buzzer wire length is long enough so soldering may be required. The other 15 minutes is me explaining my additional beeper switch. Just swapping the top panel is pretty easy and should only take an hour or two, adding the switch will add a couple more hours and require some soldering. See my motor switch video description for details on tools needed to install a switch. https://youtu.be/7TxPBVzqYDQ The FlyBeeper is available for personal use and can be downloaded at https://www.thingiverse.com/thing:458... Please note that the file isn't the most 3D printer friendly since it was designed for injection molding. I've since modified the file to be more printer friendly and have not tested it yet. Visit http://euco.us/flybeeper to purchase the panel and the entire assembly if you want so all you have to do is remove the original top panel and plug in the new one. I've received many comments about the water prevention and this mod is not very water proof just like the original panel. From what I understand the beeper itself is pretty waterproof but could oxidize quicker if water gets in. I recommend using hot glue or silicone to create a seal around the components if you ride in rain often. There are also 29mm rubber caps available on amazon and other ways to quickly prevent water intrusion, but know that if you cover the beeper, the sound will be quieter.
  6. Hi, does anyone knows what specs are the standard bms for the 20s from gotway? I'm looking specifically at the max current rating that I need for an extra battery pack. thank you
  7. can someone help me pls , my euc is not balancing, i dont know what happened. sorry i dont know how to post vids here. pls click the link TIA https://drive.google.com/drive/folders/1E63bzjbM4Ki8Tv01DA2sdAJPJvgzPnMA?usp=sharing
  8. My GotWay Msuper V2 will not connect to the GotWay app on my iPhone 7. I press 'scan' on the app and it keeps searching and searching but it doesn't find my Msuper. I am aware that the Msuper V2 only supports the older Bluetooth and not the 4.0 Bluetooth in the new iPhones. How could I solve this? Is using an older phone with the older Bluetooth the only solution?
  9. I have a programmable charger from canada, "cycle satiator" can i solder an xt60 plug to it, program to charge from the low 29v upto 84v at 0.1amps? is that a safe workaround to revive it?
  10. Hello All, I own a newer Tesla and MsuperV3S+ and since I am getting a Z10 in, I feel like I should sell one of my wheels. Please note that the Msuper I own is the 2017 model with the 1500w motor (not the upgraded Tesla 2000w). I like the fast acceleration, speed and smoothness of the Tesla on the road but I feel like I should keep the MSuperV3S+ 1300wh for distance/trail riding. If the Z10 replaces the Tesla completely as my street wheel , then I'm thinking about selling the Tesla and keep the Msuper for trail/distance riding, although I'm not sure if it would yet. I also don't want any seller's regret. What are your thoughts? Thank you!
  11. Well, I finally decided on what to buy ... and to my surprise, it wasn't a Kingsong 18. It's an MSuper 3 with the 1600 wh / 1500 w motor at 84.2 volts. The higher voltage was one of the key things that sold me. I sprang for the seat too, since frankly I think riding a EUC seated looks as awesome to me as some say it looks dorky to them, and because it should provide some relief for my back on longer rides. I'd be surprised if it really works for me since I'd have to squat really low, but there's only one way to find out ... I made a deposit with Jason and am going to put some more money on my card in the next day or two and finish up the process. Time to go buy some protective gear! Hopefully soon I will be sharing my enthusiasm more than my injury photos. Boy is this gonna freak out the dogs ...
  12. The van numbers are documented numbers and the EUC numbers are predicted. I know that you can get into some additional high fees for parking and storage for a car in the big cities. Cost of 2007 E350 1 ton van USA 100,000 miles Van $18,000 plus tax $1440 pus tag four years $128 plus Emissions four years $40 = $19,608 insurance $89 per month at 48 months $4,272 gas mileage 13 mpg $2.50 per gallon = $19,230 3 sets of tires at $580 $1,740 19 oil changes at $58 $1,102 air filters wiper blades signal light $242 only repair shiftier linkage $320 total cost $46,514 Then sold van for $3,500 End cost $43,014 that is $0.43 per mile Cost of 2011 ford Transit Connect mini van USA 96,000 miles Note: This vehicle was absolute junk.

  13. Hi guys, I've been wheeling around now for about 10 months and have a couple of queries about my MSuper V3. I've become a very confident rider now and I have my first two alarms disabled. Does anyone know what speed the third alarm will come on at? I've not heard it yet. Also, how is your top speed affected by battery power? I'm quite cautious whilst riding at around 20% (Normally to get home). Any advice is greatly received. Thank you Liam
  14. Hey just got the latest pictures from the gotway 1900 , credit to Lukas gotway
  15. Okay guys . It’s here ! It’s finally here ! @Charles McLean already did a great job reviewing his so not sure what more I can add . Opened it up and it looks identical ti his . (Opened it just to be sure I got what I paid for ) . Anyway I haven’t had a chance to really ride it yet . Battery was at 20% and it got dark pretty quickly. So I’ll take my maiden voyage tomorrow and add a bit of personal opinion afterward .
  16. Does anyone know if Gotway is planning an MSuper v4? I'd love something in an 18" form factor, Tesla 1900W motor, but with built in trolley handle and at least 1600 Wh battery. I know @Marty Backe is going to post a review of his new ACMv2 1600Wh with Tesla motor, but I'd really prefer an integrated trolley handle (which is why I bought a Tesla). Ideally (at least for me) my dream wheel would be an MSuper v4 with Tesla motor and 2400Wh battery like the Monster. Anyway, I'm just checking the rumor mill to see if I should hold off buying my next wheel! Thanks!
  17. Hi all i have just got my amazing MsuperV2 but i can’t connect the bluetooth app on my iphone, i have downloaded the app and registered with gotway, i have registered my account number as my phone number (possibly the issue but i don’t know how to change it) am i missing something i’m really hoping somebody can help thanks
  18. I am from the Netherlands. I am going to buy a Gotway MSuper MS 840. I am wondering how many ppl from the Netherlands (and Belgium too) are planning the same. If we could buy as a group, cost would be considerably lower. I think i can arrange a good deal when i can gather at least 10 ppl to buy with me in one batch. I think it is possible to lower the price from around €1600 to around €1400. The deal would be with service. guarantee and support in place. Please let me know if you are interested. I am looking to buy in one or two months time.
  19. Video: Link to the album: https://www.flickr.com/photos/143090194@N03/? I have been riding around where i live in a sitting position now for about 10 km total i think and its gets to a point where you can relax 100%. Im currently experimenting and learning this new thing and will make different seats as i go on that are taller to see what difference it makes. Edited: Video up later, my brother is working on it. recorded me riding for about 5 km
  20. On Aliexpress I found a Gotway msuper with the 1900W of the Tesla (I think). Somebody bought it here? Any more information anyone? Thanks. https://it.aliexpress.com/item/Freeshipping-Gotway-Msuper3-1640WH-Life-150KM-the-maximum-speed-of-55KM-H-the-fastest-the-most/32722898397.html?spm=a2g0s.13010208.99999999.262.zDVi7C
  21. After riding it and putting it on it's side the mSuper started beeping and when I brought it upright it won't stop beeping and doesn't self balance. The motor won't work either but there is some resistance there like the wheel won't run freely/loosely. I can turn the lights on and off using the power switch but when I hold the button down to turn it off it doesn't do anything. The button seems to work so I figure it's not that, at least I don't think that's the problem. I can connect to the Gotway App and change settings, see all the stats and it beeps to confirm any changes but the euc still won't function completly (turn off, self balance and continues to beep). I opened it up and everything inside looks fine. I've finally resorted to disconnecting the battery to get it to stop and when I connect it again it still doesn't work and does the same thing. I even tried doing a re-calibration but that didn't work either. Sometimes it does the long beep like it's trying to recalibrate but just continues to beep and the euc still won't turn off even when I push and hold the button. I've tried a bunch of things. Before this everything worked perfectly and it's only about a month old, dated July 2017. Has anyone else experienced something similar to this? Will I need to replace the circuit board? Any ideas what could be the problem? Thanks, Emile
  22. Hi all! I have search a lot around this forum and other pages but still haven't found enough detail about the controller card of the Gotway EUC's. In particular the Msuper 3 since I'm currently working on a separate power-board with either 6 sturdier MOSFET's or 12 smaller as the original. Since most controller cards share the same basic setup I suspect that we could gather "all knowledge" in the same thread. One reason to go for 12 MOSFET's is the fact that there are components that them self may cope with currents above 360A but the connector leads stop at around 160-180A. So the first data I'm asking the forum for is Q1: Has anyone done actual measurements on the currents fed thru the motor of a Msuper 3? Preferably also an oscilloscope image... I have read a lot of documentation and can really recommend the Application Note AN-941 from where I quote the summary It is advisable to follow these general guidelines should be followed when paralleling MOSFETs: Use individual gate resistors to eliminate the risk of parasitic oscillation. Ensure that paralleled devices have a tight thermal coupling. Equalize common source inductance and reduce it to a value that does not greatly impact the total switching losses at the frequency of operation. Reduce stray inductance to values that give acceptable overshoots at the maximum operating current. Ensure the gate of the MOSFET is looking into a stiff (voltage) source with as little impedance as practical. Zener diodes in gate drive circuits may cause oscillations. When needed, they should be placed on the driver side of the gate decoupling resistor(s). Capacitors in gate drive circuits slow down switching, thereby increasing the switching unbalance between devices and may cause oscillations. Stray components are minimized by a tight layout and equalized by symmetrical position of components and routing of connections. I myself have not seen the 6 MOSFET-version of Gotways circuit boards but as I have understood the "fix" is to only solder another set on top, there's no other change of components, the impedance from the driver has been left unchanged. Also, as most of you have seen, there's no individual gate resistor, only a true parallel connection with the extra MOSFET simply mounted in the same PCB-hole. This may not be so serious depending on what frequency the PWM is operating at. Which leads med over to the next question Q2: Has anyone measured the PWM frequency of the Gotway controller board? But in general I sort of have a feeling that Gotway had a larger stock of controller cards and the add-on MOSFET is a quick fix. This is one reason they are somewhat reluctant to give hardware support and spare parts, many small re-sellers have tried and failed. It's more a question of selling new EUC's than fixing the ones that break. The plan now is, as I said initially, to build a separate power board. I de-soldered all MOSFET's along with the two 1200μF capacitors. Also all three motor-wires but realised that two of them are measured for current (the ACS709 circuit). Since there's no problem in that area at all I'll feed the current to "MotoA" and "MotoC" back to the controller PCB, keep it simple. Also, the main battery connector will be moved to the Power board, all the high currents will stay there. I will use only small signal wire connection to drive the controller card. The Power board will be mounted on the heat sink and a bigger heat sink will help balancing the heat in between the MOSFET's. Won't fit that big tunnel-thingy with a fan attached but some fan with thermostat will be used. One major drawback is that the electronics is cooled down partly by "air-speed" i.e. going slow on a hot day puts cooling to a test. The stripped controller PCB will fit nicely under the siren, it needs no additional cooling of any sort. If I get no response on the question above, I'll do some measurements o my own, just being lazy here ;0) But, please help out and collect as much electronic data as possible in this thread! Or link to other threads, I'll try to compile all data here if it seems to be spread out...
  23. 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.
  24. Hey guys, Probably just a little paranoid but I've noticed that my Ms2 changed the beep tone and intensity its about 60% quieter and doesnt sound like the same tone as usual it's deeper. should i open it to check it out ? it happened after riding like 10 minutes under normal/light rain not heavy thx
  25. Hi guys, Looking for some advice really. Had my first crash today... Which I knew I would and was inevitable really. So firstly, I've set my tiltback to 42kmh using the Gotway app and disabled the first alarm. I was riding in a straight line, in a tarmac carpark and my Msuper decided it was going to chuck me off. I didn't hit any bumps, neither did my alarms go off. I didn't feel the tilt back come into play either so I was wondering if anyone knows the answer as to why I came off? I was sure the tilt back would let me know when I was getting too fast? The only thing I think it could be, was too fast acceleration?? Is that a thing? Secondly, can anyone give me advice with repairs? My Trolley handle came out as it was bouncing across the car park and has bent and will not retract. Annoyed! Also, when I turn on my wheel now, it seems to slowly tilt itself backwards when stationary? Any ideas would be a great help. Also, the wheel doesn't sit central. For the record, I rode it home fine, just a bit shook with some minor injuries. Luckily my wrist guards saved me, other than that I'm injured where there was no protection. Lesson learned. Please help, hate that I've mashed up my wheel after 2 weeks! Thank you!
