(magnet? ). WHY? Please help.? The whole Electric Bike was flooded. but the pars are still ok. Not sure with the controller. the e-motor still works. BUT, it got stuck while i was testing. At first, i can rotate the wheel freely then suddenly it is really hard to rotate. I am thinking that the magnets have something to do with it? Like its stopping the wheel from rotating. Kindly send me advise. ASAP! THANKS!
