E Active E-Bike Spider - Bosch 55mm

The Ochain E Active E-Bike Spider - Bosch 55mm is designed to make e-MTB rides smoother and more controlled by reducing the harsh feedback that can come through the pedals. With an updated construction for improved durability, it introduces a subtle degree of rotation between the crank and chainring to absorb pedal kickback and maintain better traction and comfort on rough terrain.

By allowing 9 degrees of rotation at the spider, the Ochain E Active minimizes the negative effects of chain growth on suspension performance, giving the rider a more natural pedaling feel that mimics riding without a chain. Compatible with 104 BCD chainrings in the 32-36 tooth range, it’s a simple but effective upgrade for Bosch e-bike systems that want to maximize suspension efficiency and rider comfort.
