    Bafang g020 500w rear hub - strange behaviour

    Another short update. Got a KT sine wave controller. The engine runs almost silently. Even with maximum assistance, the running noise of the tires is louder than the engine. Acceleration itself is buttery smooth.

    Bafang g020 500w rear hub - strange behaviour

    Well, personally I´d be interested if this specific controller has the same behaviour also mit other motors or if this is just a simple compatibility issue between controller and motor.

    Bafang g020 500w rear hub - strange behaviour

    Bafang g020 500w rear hub - strange behaviour

    I narrowed the story down a bit: Controller and motor cable were changed - error remains. The problem only occurs in the lower support levels or when you give full throttle with thumb throttle after lifting the bike - Ergo; Never under full load. It can't be a fallen off permamagnet, because...

    Hi everyone, Last week I got a brand new Bafang g020 500w 48v rear hub motor. While riding along a friend with an ordinary bike, I noticed that sometimes when the PAS kicks in there is a noticeable shock going thtough the bike combined with a dull noise. After that the bike works fine as...
