Bafang's new super powerful and efficient BBS03 aka BBSHD 1000 watt mid drive motor will fit virtually any bike with JIS/BSA standard bottom brackets. With the proper adaptors it can also fit BB30, PF30, American/bmx, and Shimano Press Fit 41 BB92 with adaptor seen here. It comes with square tapered spindle shafts in several widths including 68mm, 73mm, 100mm, 110mm, and 120mm widths. This new motor will fit in 100mm fat bike bottom brackets like the Surly Pugsly or the BikesDirect.com Motobecane Fat bikes. More information on what bikes the motor can fit into is found here. We set all motors to 1000 watts unless you request 750 watts prior to shipping. The peak power of this motor is approx 1500 watts and has a robust 12 FET controller. Another feature to notice is the addition of the gear sensor connector built into the controller, its the yellow plug seen in the wiring harness photo above and it allows for installation of the gear sensor at the rear deraileur location.
