For mounting various standard chainrings
This Bafang BBS01 and BBS02 adapter can be used for standard chainrings with 104 or 130 mm BCD. You can use 1 or 2 chainrings.
It´s also possible to use two chainrings, one for uphill with plenty of torque and one for high speed. The availability of standard chainrings is huge. You have to mount the chainring on the inside. The mounting bolts are included. Longer M5 14 mm screws are eventually required (if you mount 2 chainrings).
When mounting 2 chainrings, you also have to use 1-2 spacers - otherwise the screws touch the motor housing (see video below).
The inner hole has a diameter of about 50 mm, the bolt circle of the chainring bolts has about 60 mm.
Doesn't work with Bafang BBSHD! For this motor you have to use this product.
