Bafang BBS01B 250w 48v Electric Bike Conversion Kit
Amazon.co.ukDescription
The Bafang BBS01B 250w 48v is a safe bet if you want to stay on the right side of the law. It doesn’t have the raw power or grin factor of the 500w or 750w, but you can ride it to your hearts content safe in the knowledge that your e-bike is legal.

Summary
Thanks to its ‘plug and play’ design the Bafang BBS01B will fit a majority of regular bicycles with a few exceptions. Providing your bike has a standard BSA threaded bottom bracket then installation should be fairly straightforward for the competent DIY enthusiast.
The Bafang BBS01B 36v 250w is the perfect conversion kit for a daily commuter or leisure bike. You can even add this kit to your mountain bike to make riding on steep trails less of an effort.
If you don’t mind experimenting with the controller settings you can purchase a USB programming cable and download the free open source software – for more information on how to do this safely, follow the instructions on Karl’s electricbike-blog. The 250w and 350w are the same motor, the only difference is the 250w is set at 15A and the 350w is 18A. Obviously to stay within the confines of the law you should not increase the motor current as this will also increase the continuous power output. You can still fine-tune the pedal assist parameters and make the BBS01B super-smooth on the uptake.
Neat installation – because of the design, a Bafang BBS01B installation if done correctly will result in a very neat and professional looking e-bike conversion.
Choose your power! Most of the Bafang display units allow the rider to choose from up to 9 gradually incremented levels of assist. This means that you as the rider can either decide to stay within your comfort zone (for pedalling) or maybe push yourself that little bit hard and share the workload with the motor. I have written a separate article on using an e-bike to get fit and lose weight on my other website.
