This is the Lock Ring and O-ring kit to hold the front chainring and/or spider onto the motor drive pinion on the Bosch Gen 4 Drive Unit (BDU4XX)


Substantially tougher than the plastic nuts, although be careful not to cross thread the nut on the drive unit assembly.


PLEASE NOTE: If you have a Bosch Classic +, Active Plus or Performance system (Featuring a small sprocket on the front), you will require a different lockring.


We also sell the Bosch Spider Tool to safely remove and replace this nut. Available from our store.


Just to confirm it's to fit the following motor shape. If you require a Classic+ lock ring, you can find it on the dedicated Bosch Classic Lock Ring page.

Peter Chittum
Handy eMTB parts supplier

Finding parts for e-bikes is challenging on normal bicycle supplier e-commerce websites. Very handy to find a specialist that caters to the growing e-bike market. Was able to easily find the part I needed. Even better that they're local to me. Only disappointment is that they don't have a walk-in showroom, and it's by appointment only.
