Hello Hugh,

I like the Bafang very much. Mine is a BBS01 unit and I have modified it to provide a double 52/39 chainring.
They really can rip along quite nicely can't they. I have found that a tiny squeeze on either brake lever is required to instantly cut the motor for gear changing really helps, but I have to say I am really impressed.
30 miles on a single 36V 20AH battery seems to be the limit on mine. How far does your take you?
