Bafang 750W Middrive Motor Upgrade for Catrike - This powerhouse provides maximum power to the rear wheel. This will give you the best climbing power as well as the highest top speeds. It is paired with the 860C color computer console which allows you to program up to 9 levels of assist. Can be controlled automatically by pedaling or by using the throttle. 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.
