Bafang Install on 73mm Bottom Bracket
Bafang Motor Installation on a 73mm bottom bracket
When installing the motor on a 73mm bottom bracket, the outer lockring may not fit. You need to use the extra washers and longer M6x20mm bolts provided in your kit. We provide both the extra washers and longer bolts for free with all of our kits. If you want, you can use Loctite on the threads of your axle instead of using the outer lockring.
