The Bafang BBS02 750 watt complete motor kit with ebike battery is a high-performing, lightweight, quiet, fast, hill-climbing, well-engineered electric bike kit. 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 750W Mid-Drive Motor offers both throttle and pedal assist power. You can always use the throttle in order to engage the motor if you want to take a break from pedaling! These Mid-Drive Motor have a surprising amount of torque and are fast as they are designed to be able to go 25+ MPH depending on gearing!
The Bafang 750W Mid-Drive Motor is superior to both Rear and Front Hub Motors because it offers a balanced low center of gravity. On a standard bike, the weight of the motor is balanced directly in the middle of the bike down in your bikes bottom bracket. This allows for a better riding experience with a balanced low center of gravity with this motor located in your bike's bottom bracket.
The Bafang 750W Mid-Drive Motor is superior to both Rear and Front Hub Motors because the full power of the motor acts on your bike's chain transmitting the power directly to your bike's rear gears. This allows for the power of the motor to be transmitted directly into your bike's existing drivetrain leveraging your bike's rear gears for superior performance through mechanical performance.
Our kit includes all of the the necessary hardware and equipment to install our Bafang 750W Mid-Drive Motor on your bike (your specific bike may need add-ons in order to work with our kit). There are extra add-ons available, however our baseline kit includes many of the parts which other companies piece meal out and charge more for!

This was very easy to install and it works extremely well, omg bout through me of the bike. Very impressive power and speed. Only issue I had was with the length of the pig tale wires to the break handle and throttle they needed to be 2” longer due to the large handle bars on this bike but we made it work. Shipped on time but fedex was slow to get it here.
Installation went well but I had a question about connecting the gear sensor to the motor. I sent a request for assistance and got a response quickly. The only other small issue was that the screw that locks the speed sensor magnet was a tamper proof torx style. It would be nice to include a compatible bit in the kit.
I am very happy with new electric bike. I have a 2004 Trek 7300 that I put the Bafang kit on. Wow 8th gear, power setting 9 riding into 15 mph wind and I'm cruising at 25mph !!!
Ordered the kit after doing all the pre-checks. Everything arrived and was ready to start setting up. For someone who never worked on removing bottom brackets and pedals etc, it was super easy. And when I finally put the last connection together to do my first test, everything worked perfectly. The gear sensor which I thought was going to be hard worked without a flaw. Just had to watch a quick youtube video for getting my gears perfect again after removing the rear derailleur cable. My first ride which I was only going to head around the block ended up being a few miles. My next ride was more, then 2 beach trips with the last being 20 miles total. Some of you might buy this like me thinking you will just ride like a powered bike and not pedal but the pedal assist makes you just go way farther without ever getting tired. So you will use it to go as far as you can once you realize you are just letting the motor help you. You in turn help the the battery charge from draining as fast with your tiny bit of effort. Included a pic of my setup. My old 1998 Cannondale Super V is back on the road for the Summer beach trips.
I have not used it yet since it will take me sometime to fit the kit to my bike. But it all seems to be well thought out so far.
