Donor bike should have a standard bottom bracket shell between 68-73mm, but not exceeding 73mm. If your bike has a 73mm bottom bracket shell, please let us know in the notes section when going through the checkout proces, and we can included longer motor bracket bolts, along with some washers. Carbon frame bikes would not be compatible with the Bafang mid drive motor kits.

The kit is supplied with a 46 tooth single chainwheel, so if your bike has a front derailleur it will not be required.

The brake levers are cable operated, so will not be compatible with hydraulic brakes. We also stock brake sensors for use with hydraulic brakes, which are compatible with Bafang motor kits.

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

Motor kit comes with 1 year limited warranty.

I've fitted one of these to a hybrid bike, it works perfectly and done over 1500 miles so far. My last bike had a hub motor, but I had always wanted one of these. There are plenty of videos on YouTube about these kits. Eclipsebikes has the best price compared to eBay. Review submitted 08/15/2018.

I bought the Bafang bbs01b 36v 250w motor kit and a 14.5AH Hailong battery for my Specialized Crosstrail Pro hybrid bike. The fitting of the kit was painless. I use the power assist without the supplied throttle and get an impressive range between charges. Dealings with Eclipsebikes has been excellent. Just bought a second kit and fitted it to my wife's bike. Great fun, new lease of life for our cycling and highly recommended. Review submitted 01/12/2019.

I ordered the motor on a Wednesday and it arrived midday Friday and was fitted to the bike on Saturday morning. So first off thank you Eclipsebikes for this excellent service. Communication was good and included a link to fitting instructions and a download of the display manual. I have fitted a hub motor to a tandem before so have some experience with conversions. I was pleasantly surprised at the quality of the kit, in particular the water proof wiring connections and the replacement brake levers (containing cut off sensors) which were head and shoulders above the quality of those supplied with the hub kit from a different supplier. I was converting an old 1990's racing bicycle which I had previously changed to straight bars and twist shifters. The conversion was actually really straightforward. However like most tasks of this kind its important to have the correct, decent quality tools. Its crucial in my opinion to have the special Bafang motor spanner to fit the main nut and lo
