Bafang BBS01B 36V 350W Mid Drive Motor Kit -

The Bafang mid drive motor kit is a popular ebike conversion kit, which we have been supplying since 2014. This tried and tested ebike kit is well regarded within the ebike community, with spare parts and installation / maintenance information readily available online.

The Bafang BBS01B 36V 250 watt mid drive motor kit offers a good combination of strong torque, high efficiency with low power consumption and noise output. The motors central mounting position results in a balanced low center of gravity, with power output transferred through the bikes drivechain, meaning the motor can operate within its optimum RPM range.

The Bafang kits we supply are the newest version available, with dedicated light and gear shift sensor connectors.

Additional Info:

The Bafang conversion kits can be fitted to standard bike frames, through a simple installation process. The donor bike should have a standard bottom bracket width between 68-73mm (not exceeding 73mm), with an inside diameter of approximately 33.6mm - 33.9mm. Longer bolts and washers are included for bikes with a 73mm bottom bracket shell. Carbon frame bikes would likely not be compatible with the Bafang mid drive motor kits, due to increased shell thickness.

The Bafang kit is supplied with a 44T, 46T or 48T tooth single chain ring, so if your bike has a front derailleur it will not be required. 

The supplied brake cutoff levers are cable operated, so will not be compatible with hydraulic brakes. Should you require hydraulic brake sensors including with the kit, please select this option from the drop down list.

We add additional high quality Mobil SHC 100 Synthetic Red Lithium Grease to the secondary reduction gears before dispatching motor kits.

Motor kit is intended for off road use only, as it exceeds the legal power limit of 250 watts. Click here to see government guidelines covering electric bikes.

We are a UK based company, with all stock dispatched from within the UK. Motor kits comes with 1 year limited warranty.

My kit arrived speedily and very well packed by EclipseBikes. Fitting instructions were pretty good but by no means complete -I had no idea what the unassisted power control was until I tested the build and there was no mention of having to replace the brake levers. I hit a snag straight away because the 2 screws fitting into the motor weren't long enough even though my bottom bracket was within limits as far as I knew! So I had to source longer ones from my spares stash. From then everything fitted pretty well and all connectors were colour coded for convenience. The connectors from the motor to the battery though did not appear to be waterproof so this needed sealing with tape. The only other niggle was the screw for the speed sensor magnet which was not finished correctly preventing the insertion of an Allen key - spares stash came in useful again. Several cable ties were used to secure all the wiring (not supplied). All this took about 4 hours in total and I was happily surprised b
