The Bafang mid-drive BBSHD 750w motor mounts in place of your bike's bottom bracket and replaces your bike's crankset and front derailleur if you have one. 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 Bafang BBS02 kit comes with all necessary parts to convert just about any bike (must have 68-73mm bottom bracket) to an electric bike except the battery! We also sell the Complete Bafang BBS02 Mid-Drive Motor Kit with the battery, so you have everything you need to transform your bike into a high-powered electric bike! 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.

These kits will only work on bikes with 68mm and 73mm bottom brackets, which is most bikes with the exception of fat bikes and beach cruisers. Please confirm the size of your bike's bottom bracket and check for compatibility before purchasing as described on our "Will the Bafang Mid-Drive Motors fit on your Bike?" article.

The Bafang motor conversion kit installation is a DIY project that requires no specialty expertise – simply install the parts, plug in the connectors and zip-tie the cables! The trickiest part of the install process is removing your bike’s existing parts, such as your bike's bottom bracket. If you are not interested in performing the install yourself, simply stop by your local bike shop, and they should easily be able to install the BBS02 kit for you.
All the tools that you will need for the install are typically found in most bike tool kits. The only tools that you will need for the install are:
1. A 15mm wrench or pedal wrench to remove your bike's pedals.
2. The appropriate bottom bracket tool to remove your specific bike's bottom bracket
3. Allen wrench(es)/screwdriver to remove your brake levers, rear derailleur, and chainring.
4. A chain tool to remove your bike's chain.
5. A standard spanner wrench to tighten the lockrings.
6. Allen wrench(es) and a Phillip's head screwdriver to tighten the crank arms, sprocket, display, throttle and brake levers.
No specialty tools are necessary! Please note that this kit does not include any tools.
