kuechi Posted September 15, 2019 Share Posted September 15, 2019 The other i was on my usual route. About half way the wheel started to jerk like crazy. I turned it off and on again but still after a couple feet wheeling it it jerks again. I opened up the wheel, checking the mother board, connections and axle. It seems that everything is tight and good. I accidentally reset the wheel my unplgging the battery connectors and pushing the button again to discharge. I put back all the screws and casing of the wheel and tried it last night and it was fine now. Do you guys think it was a software issue? I’m on the latest firmware. I didn’t see any debris stuck on the wheel while opening. Hopefully it stays good that way. Quote Link to comment Share on other sites More sharing options...
TomOnWheels Posted September 15, 2019 Share Posted September 15, 2019 Very strange... Well it looks like a software issue... but I guess it doesn't feel good/safe... Quote Link to comment Share on other sites More sharing options...
KC137 Posted October 8, 2019 Share Posted October 8, 2019 I too have experienced this yesterday. First power cut off while in Trolley mode. After Turning it back on and trolleying for 100 ft or so it started violently shaking. I was able to turn it off. I've rode it home after without any issues. Still quite alarming. Will be asking my supplier for more info Quote Link to comment Share on other sites More sharing options...

Or wiring fault (check wires). As complex as they may seem, its just a few basic subsytems to diagnose. I would venture to say that checking the board and its mountings, along with pedal hangers was a good first idea. FIrmware is so easy, silly not to check it. Where you at @Eric plam? Surely you've fixed it or discarded by now... Edited January 13, 2021 by ShanesPlanet Quote Link to comment Share on other sites More sharing options...
Dennis kush Posted January 27, 2023 Share Posted January 27, 2023 My king song 18xl is also shaking and gets worse and worse. I open it tighten loos screws on the pedal mount but that doesn't seem to make any difference. The problem goes away,how? I don't know. And a day or three later it happens again until it goes away. Turning it around and riding back in front some times helps and some times it doesn't. Any one have any more info on this? Quote Link to comment Share on other sites More sharing options...

Paul A Posted January 27, 2023 Share Posted January 27, 2023 1 hour ago, Dennis kush said: Any one have any more info on this? The six bolts that attach the case to the metal pedal hangars need to be tightened. Also apply low strength thread locker, to prevent the bolts from loosening again. That will fix the problem. No more violent shaking/vibrating. Quote Link to comment Share on other sites More sharing options...

Turning it around and riding back in front some times helps and some times it doesn't. Any one have any more info on this? Most cases where the body starts shaking. Is when the plastic around pedal hangers are cracked.. If plastic is cracked - the screws that hold the body to pedals, isn't holding anymore.. It's that "box" like shape that goes around pedals. Check the "box" corners for cracks. (You need to bend/move the plastic little bit, or you may even miss the cracks..) Another thing usually is when screws come loose, be pedals or motherboard. 1 Quote Link to comment Share on other sites More sharing options...
Paul A Posted January 27, 2023 Share Posted January 27, 2023 If the plastic is cracked, a plastic glue might help. Have not used a plastic glue, don't know how strong and effective they are. Could mean end of life for an EUC if cheap plastic breaks. Need to improve design. Quote Link to comment Share on other sites More sharing options...

Need to improve design. 2 compound resin + some fabric does wonders on euc body.. You don't need to buy any new shell - ever. Plastic glue "alone" are weak.. The fabric is most important part when glueing something! It gives the structural strength. (Strings hold the crack together. Simple glue will crack again..) 1 Quote Link to comment Share on other sites More sharing options...
