The transmission system of the powerful medium-sized electric electric motor of the electric bicycle of the transmission system is subjected to a large continuous load. Torque Arm Predicated on this fact, we not only 
give a specific electric bicycle chain, but provide sprocket for Bosch electric motor and internal gear hub.
Our chains are ideal for electric bikes with narrow tolerances, high-end materials and excellent corrosion resistance.
Electrical bicycles with gearboxes ought to be equipped with high-end drive sprocketes since the wear upon the sprocket and chain can be interdependent. It really is obvious that the quality of the sprocket and the chain should match.
