Hello Everyone! I'm new here and a Friend gave me his Ninebot ES2 because it doesn't work anymore. I have disassembled the whole thing and the main probem was overheating/melting of the three power cables, coming from the driver board, to the motor. I could fix those (not using plugs, but instead solder them directly), but the driverboard itselve has at least two blown parts, show in this picture: Can somenoe tell me what parts those are? Number one could be a smd transistor, like those above the microcontroller. About number two, i'm not so sure, it's an smd part with six pins. Thanks in advance Fat Unicorn

My ancient sbuv3, very similar/same motor as solowheel, is (increasingly) misaligned, it balances at a slightly oblique vertical axis. Riding is uncomfortable therefore, even a little unstable, when compared to another EUC of the same make/model, which goes fine. Is there a mechanical adjustment inside the motor? Which side of the motor should I open? Do you have photos showing the inside? I suspect a loosened PCB. Or an accelerometer IC is subject to aging. I'm read that there are people who know this EUC motor: https://forum.electricunicycle.org/topic/13393-how-to-remove-pedalscranks-access-motor-on-solowheel-xtreme/ Thanks for any advice, Paul -
If anyone can shed some light on this I'd be most appreciative. I tore down my IPS Zero 260 because it simply wouldn't charge anymore. This, after a few stages of degrading performance (e.g. a one-off cutout at low speed, limited range, erroneous low battery warning, wouldn't charge past 80% or so, etc.). These occurred over a period of a few months of daily use. Thinking that I had bad cells (I don't know, just guessing) I decided to remove the battery pack and get an estimate to build a new one. I know it'll be tough to afford that but I hate being without my EUC. As I got into it I also checked all the connections and wires for any sign of shorts. Finding no serious wiring issues I decided to look at the board and this is what I found (see pics). Link to full resolution pics in my Google drive: https://drive.google.com/folderview?id=1ML7ZwkBCOBkzBhUFISRJnN_qxOSg1ZkY I'm certainly no expert but it doesn't look good to me. Could the corrosion and water damage seen in the pics be the cause of all my issues? Replacing the batteries will likely be prohibitive but a board repaired might be doable. But, I'd hate to do a board repair only to find out I've not solved the problems and that I'll still need batteries. Any thoughts? Also, if you know of anyone who could do the work please give recommendations. I'm in south Orange County CA. -
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.

ACM v3 S+ 1600w & Monster 1600w / Istanbul
mumtaz posted a topic in Begode (Gotway) and Extreme Bull
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 -
Hello everybody, I have an IPS 101 and the electronic board (pcb) is damaged, where can I acquire a compatible replacement for this unicycle? It is 16" wheel
