The EBIKE24 Lockring Tool is a lockring tool for mounting or removing the chainring lockring on Bosch 3rd and 4th generation e-bike drives, Yamaha PW-X and Brose motors. This allows worn chainrings to be replaced or the motor unit to be exposed for maintenance work. The puller, which is made in Germany, was CNC-milled from high-quality steel and is therefore extremely robust and durable. It is suitable for both specialist workshops and home hobby workshops.

Note: The lockring tool requires a suitable socket spanner / ratchet (1/2″) or a 24 mm open-end spanner when in use. It should be noted that the puller has a left-hand thread and is therefore turned clockwise when dismantling. When tightening the lock ring, the torque specified by the manufacturer should be observed.
