I have a Bafang hub kit with 500 W 48 V that I mounted on a 26" mountain bike. I throttle with a thumb control. Everything worked perfectly for six months when one day the motor suddenly started to chop. I then changed to a new similar motor controller and everything worked again for a couple of months until the same thing happened again. A few months later I tried again, everything worked for a couple of days but then the same problem returned.
I haven't opened the engine but don't think the problem is there.
Anyone recognize the problem and know how to fix it?
Can I maybe change to a controller for 750 W if it can withstand more?
