The transmission system of the powerful medium-sized electric motor of the electric bicycle of the transmission system is put through a large continuous load. Predicated on this reality, we 
not only give a specific electric bicycle chain, but provide sprocket for Bosch motor and internal gear hub.
Our chains are ideal for electric bikes with narrow tolerances, high-end components and excellent corrosion level of resistance.
Electric bicycles with gearboxes should be equipped with high-end drive sprocketes since the wear upon the sprocket and chain is interdependent. It is obvious that the grade of the sprocket and the chain should match.
