    Can anyone help re Suzhou Bafang 250 watt humming but not turning the wheel?

    I recently had a 250 watt Suzhou Bafang which was in good working order rebuilt into a new rim. Now with everything reconnected when I work the throttle the motor makes a loud humming noise but does not drive the wheel. There is also a much quieter whirring noise inside the hub as though the...

    Conditioning new lithium battery without riding the bike?!

    Can I safely fit and run 24 volt motor on a 36 volt system

    The hub on our Mistral has broken (it is not the pawls) so that the pedals will no longer turn the hub. As the 36 volt battery, controller, etc are all in good order, and I happen to have a 250 watt Suzhou Bafang 24 volt motor to hand would it be safe to fit that in place of the existing 36...

    Charger amperage for LifePO4

    Can anyone advise if it would be safe to use a 24 volt 1.8 amp output Lion charger to charge a 24 volt LifePo4 battery whose dedicated charger is 24 volt 4 amp output? I have more than enough 24 volt 1.8 amp chargers and if the only penalty was a much longer charge time I would prefer to use...
