Extension Modification Kits-100mm and 120mm Easy Install Bafang BBS02


California Ebike, the original, introduces the NEW PRESS IN 100mm and 120mm BBS01/02 modification kits. This kits do not require the threading tools and special tooling that our original kit required. All one needs to do is dis assemble the BBS01/02 as before, (see video) and install the the new components as shown. For a more permanent install, you may want to use structural epoxy when assembling the extension tube or TIG weld the extension tube to the Bafang axle tube once it is pressed into place. We feel this kit will make converting your Bafang mid drive to fit a FAT Bike much easier and definately more cost effective.
