Bosch Lockring Performance Line Gen.4 Smart System & eBike System 2

Bosch eBike lockring Performance Line Gen.4 for mounting chainring or chainring spider. The lock ring ensures a firm hold for your chainring. To prevent the chainring from loosening by itself, the lockring must be installed with the matching Bosch O-ring. The lockring is compatible with various Bosch Performance Line and Cargo Line eBike motors with Smart System and the older Bosch eBike System 2. To check whether your eBike is compatible, we recommend our compatibility list below.

Assembly instructions for the Bosch eBike lockring Performance Line Gen.4

To ensure a safe and perfect function, please observe the correct tightening torque. To prevent unintentional loosening, the lockring should be tightened to 25 - 30 Nm. Use an appropriate torque spanner for this. For additional security, you should use the O-ring, which can be ordered on request. You will also need a special lockring tool for assembly and disassembly.
