Steven Dilema Louis Posted March 20, 2018 Share Posted March 20, 2018 was wondering if anyone has had the symptoms of switching on the unit, and an instant (usual beep), then a thudding sound then the unit switches off with no sound, to push it along, it shudders as it rolls, which leads me to believe its the dreaded mosfets, if so yet another motherboard........

Ffs Stuttering wheel is a dead giveaway of fried controller/mosfets. Try to disconnect the motor cables from the motherboard to be sure. Link to comment Share on other sites More sharing options...

Stabio Posted May 2, 2018 Share Posted May 2, 2018 This may sound stupid but I had a similar problem. I would turn on the 9B 1 it would shutter and then turn of. I accidentally turned on the lock in my phone app. Once the lock was off everything was fine. I'm very new to riding. So far I have completed a drunken 50m. Little or no control of directions.

Welcome to EUC world! What you describe is a different matter. OP mentioned stuttering while pushing the wheel (powered off). Link to comment Share on other sites More sharing options...
