Product Details

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 overpower your designated PAS level with your throttle in order to achieve your desired speed and power.

Which Sprocket?

We offer the Bafang BBS02 kit with three sprocket options with different tooth sizes (44T, 48T and 52T).

44 tooth is the smallest option that will provide you with the most torque and it is the best option for hill-climbing ability.

48 tooth is a reliable middle of the ride option.

52 tooth is the largest option and will provide you with the highest top speed (~30mph) and it is recommended to be used mainly for street riding.

Which Battery?

The battery that you choose to pair with your kit depends on what kind of range and power you are looking for as well as the dimensions that you have to work with on your bike.

Please consult the different battery product pages for detailed information regarding the batteries:

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. T
he 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.

Will the Bafang BBS02 750W Motor Kit work with my bike?

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. Please confirm the size of your bike’s bottom bracket before purchasing. Please visit our FAQ Page for information on how to measure your bike's bottom bracket.

If you still have questions after confirming your bike's bottom bracket size, about whether your bike is compatible with the kit, please send us an email with the year, make and model of your bike to [email protected]


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 & Bafang LCD Display manual downloads.

Customer Care Note: We always recommend storing ebikes indoors or under cover as electronic components are susceptible to water damage. All of the kit parts are water resistant, but components such as the display are not waterproof.

Amazing Acceleration! June 7, 2019
Reviewer: Libby Harrow from Fruita, CO United States  
This is super motor!  The actual installation of the kit would have been an hour or a little more.  I did run into complications with the components on my bike that required me to install a different shifter & derailleur due to my brake levers being integrated in with the shifters.  I am a 68 year old woman who has managed bike shops for 20 years, but never as a mechanic.  My experience is mostly working on my own fleet of personal bikes.  I programmed the handlebar module to top out at 30 mph and when tested, actually attained 32 mph, while spinning the pedals with little resistance.  I have ridden 28 miles now and the battery is only down one bar on the indicator, so the range on one charge is not known as yet, but appears to be much longer than anticipated.

Great Support June 4, 2019
Reviewer: Bob Hartzler from St. Paul, MN United States  
This is the second motor I've installed. Every bike is a bit different and although I'm a reasonable bike mechanic, I still had a couple problems. Turned out it was my mistake but the support staff was very responsive and helped me figure it out.

Best purchase I have made in a while May 23, 2019
Reviewer: Marshall L. from Coarsegold, Ca  
I purchased the 750 w motor kit with the 52v battery about a year ago and today hit 1,000 miles. The installation on my 30 year old Specalized Hard Rock classic was fairly easy since I have the requisite tools, though I did have to replace the chain for the correct length. At this point there have been no issues with the kit or battery degradation.
When I selected this unit and supplier it was to help me rehabilitate after a really rough course of radiation treatment and several months of being bed bound. By utilizing the power assist I was able to get out of the house and enjoy the outdoors while building muscle and appetite. I'm in better shape now than I have been in 20 years. I have ridden the bike in just about every terrain you can imagine and it just keeps on going. This product is a great deal to help with getting outdoors and enjoying getting some physical activity.

More than I expected May 22, 2019
Reviewer: Carl M from Durham, NC United States  
This kit has a very powerful motor and a very large battery. installation was fairly simple for me, but I've been working on bikes for many years.  

The way the power comes on when pedaling is not very natural to me, but I use the thumb lever most of the time when I need a boost.  It is a new style of riding for sure.  
I am interested to see what settings I can change in the firmware. I rode a pedigo bike and they had it set in a smart way... Using different power levels, and then one setting for throttle only, no pedal assist.
So far, I have only used level 1 or 2 for most of my riding.  My battery is still full after 20 plus miles.
I am still learning, I'm thrilled with the install, and it has more than enough power to pull 100 lb trailer without assistance, or with.  I would have known hesitation recommending this setup to anyone.
 If there was a cheaper kit that had a 500 watt motor and a smaller battery, I would have jumped all over it.
