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. These kits will only work on bikes with 68mm & 73mm bottom brackets, which is most bikes with the exception of fat bikes and beach cruisers.
Watch our step-by-step Installation Video here.
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.
Please refer to our Installation Page for our video with step-by-step installation instructions.
