The transmission system of the powerful medium-sized electric motor of the electric bicycle of the transmission system is put Pulley through a large constant load. Based on this truth, we not only provide a specific electric bike chain, but also provide sprocket for Bosch motor and internal equipment hub.

Our chains are well suited for electric bikes with narrow tolerances, high-end components and excellent corrosion resistance.

Electrical bicycles with gearboxes ought to be built with high-end drive sprocketes because the wear on the sprocket and chain is interdependent. It is obvious that the grade of the sprocket and the chain should match.
