Standard offset compatibility: Bosch CX Gen 4 (BDU37) Bosch CX Gen 5 (BDU38) Yamaha PW-X This is a guide only, please check the clearance on your bike using the guide below. We are Amflow dealers, and we recommend the narrow fitment version of these cranks for Amflow ebikes. Amflow spacing sits between the two sizes, but there is clearance for the narrow fit. If you have another Avinox powered ebike, both the standard and the narrow version will fit the motors, which set you choose depends on the clearance of your particular bike.
