Original BOSCH® chainring spider


The original chainring spider is used to mount the chainring on the BOSCH® GEN3 eBike motor (BDU3xx).
The bolt circle diameter of the chainring mount is 104mm.
 

What is the BOSCH® e-bike chainring spider needed for?

The Bosch Spider is the connecting piece between the chainring and the motor and transmits the drive forces generated by the pedal force. Different chainrings can be mounted on the BOSCH® Chainring Spider. After changing the chainring, the BOSCH® Spider is screwed to the BOSCH® motor using the Spider tool and the Lock ring.

To change the chainring, we recommend dismantling the Spider so that you can easily access the chainring nuts. To be able to loosen the aluminium lock ring without damaging it, you need the spider tool for Bosch Active from 2018 eBikes.
