The transmission system of the powerful medium-sized electric motor of the electric Chain bicycle 
of the transmission system is put through a large continuous load. Based on this truth, we not only give a specific electric bicycle chain, but provide sprocket for Bosch motor and internal equipment hub.
Our chains are well suited for electrical bikes with narrow tolerances, high-end components and excellent corrosion resistance.
Electric bicycles with gearboxes should be equipped with high-end drive sprocketes since the wear on the sprocket and chain is definitely interdependent. It really is obvious that the quality of the sprocket and the chain should match.
