Hi there! In this video I am using a BBS02B mid drive kit by Bafang to convert a fat tire mountain bike into a fast and highly capable e-bike. With a battery capacity of just over 800Wh, the e-bike is able to push over 1200W into the rear wheel. The battery mount and a few other parts are 3D printed and are holding just fine after more than 500 km of test riding. Currently my favorite e-bike.

Thanks for watching!
