I have a very low step through Bernds Tandem with belt drive. I can mount a Bafang mid drive motor into a kiddie crank I attached to the frame above the front chain set. I can fit a 30 tooth 104BCD chainring to the Bafang and the chain set. The motor will drive downwards to the chainset and the cranks will not be attached to the Bafang.
Has anyone tried this or anything similar?
Do you think it will work?
My main thought is that the "freewheel" in the Bafang motor will not be needed or work at all and the cut out when we stop pedalling will need adjusting via the computer program to stop immediately. But will this stop the motor when we stop pedalling straight away and is it safe?
I do of course realise that I could use hub motors, change the whole drive system etc etc. But I have a Bafang motor and most of the bits so want to give it a try. AND the Bafang
cannot be fitted to the existing bottom brackets for at least three valid reasons. Any help or suggestions much appreciated.
