Bafang BBS-02 48volt 750watt Motor Assist - More power than the 500w version; this is a great option for those of you who are really into off-roading or for those who always seem to be climbing steep hills. The Bafang is a surprisingly quiet mid drive option that will add a lot of power to your ride. This is a great set up for those of you with a single chainring on your front crankset.
