E-Bike Lock Ring Tool – Bosch Active & Performance Gen.2

The Bosch Ebike24 lock ring tool is used specifically to loosen and tighten the lock ring on Bosch drives. This serves to fix the e-bike chainring.

The tool holder is suitable for standard 1/2-inch ratchets or a 24/25mm open-end spanner. This ensures the greatest possible compatibility with the toolbox at home.

Due to the production on modern milling machines and the use of a high-quality steel, it is 100% accurate, safe and particularly durable.

You can use our tool on all Bosch e-bikes with Active and Performance Line drive from model year 2014 of the 2nd generation with 50mm lockring (ring outer diameter measured).

The following Bosch product lines are not compatible with the Bosch Ebike24 lockring tool:

• Active-Line 2014 – 2017 (BDU2XX) – (from 2018 = large chainring in front – different gear puller)
• Performance-Line (BDU2XX) – (from 2020 = large chainring in front – different gear puller)
• Performance CX-Line (BDU2XX) – (from 2020 = large chainring in front – different gear puller)

Attention – left-hand thread!
The motor shaft of the Bosch mid-motor has a left-hand thread. It is therefore loosened clockwise and tightened counterclockwise.
