Perfect for wider bottom brackets in combination with BBS01 & BBS02 motors
All you need to do is disassemble the BBS01/02 and install the the new components as shown. This kit will convert your Bafang mid drive to fit in a FAT Bike much easier. For a more permanent install, you may use structural epoxy when assembling the extension tube or TIG weld the extension tube to the Bafang axle axle once it is pressed into place.
The axle is a bit longer than 100 mm, since most Fatbikes have a wide chainstay and is better to make it wider to not touch with the cranks. Eventually you need to use some spacer using BB92.
