The Bafang mid-drive BBS02 750w motor mounts in place of your bike's bottom bracket and replaces your bike's crankset and front derailleur if you have one. The Bafang BBS02 kit comes with all necessary parts to convert just about any bike (must have 68-73mm bottom bracket) to an electric bike including the battery! This is the newest Bafang 750w BBS02 mid drive motor kit, including version B motor and upgraded 25 amp controller with 9 IRFB3077 MOSFETs. The BBS02 750 watt motor kit is a high-performing, lightweight, quiet, fast, hill-climbing, well-engineered electric bike kit. Superior to hub motors, the mid drive motor kit feels just like a normal bike when pedaling since it can completely freewheel. The motor includes pedal assist sensors (PAS), so you can choose the power level of motor assistance that you would like while pedaling. Also, you can always use the throttle in order to engage the motor if you want to take a break from pedaling! Please note, the throttle is limited to the Pedal Assist Level you are in.

Choose a 52V Battery to Turbocharge your Bafang Kit
52V Battery packs are designed to turbocharge your 48V Bafang BBS02/BBSHD ebike kits by maxing out the possible amount of voltage that the 48V Bafang controllers can handle to get the most possible power out of your 48V ebike system. 52V batteries give your 48V Bafang systems more power and longer range. The 52V pack gives you an extra 200 watts more than a 48V pack. The added voltage also provides you higher top end speed, more power and a longer distance range compared to a 48V ebike battery pack with the same amp hour rating. A 52V battery will give you ~8% longer range than a 48V battery with same amp hour rating. All our Bafang motor kits (BBS02/BBSHD) are compatible with 52V batteries as our upgraded, robust controllers are made to handle a maximum of 52 volts.
Please make sure and use our Actual Size Battery Cutouts to check for fitment on your frame to make sure the battery will work on your bike frame.
Will the Bafang BBS02 750W Motor Kit work with my bike?
Please confirm the size of your bike’s bottom bracket size and compatibility before purchasing as described on our "Will the Bafang Mid-Drive Motors fit on your Bike?" article.
