Bafang BBS M33 Installation Spanner Tool -

Suitable for use with the Bafang BBS01B, BBS02B and BBSHD mid drive motor kits.

The dual purpose spanner is designed to fit the inner 4 notch M33 nut and the outer locknut.

Ensure that the inner 4 notch M33 nut is well tightened, which will avoid the motor slipping and rotating on the bikes bottom bracket shell. The outer locknut is made of aluminium and doesn't need to be tightened as much as the inner 4 notch M33 nut.
