The transmission system of the powerful medium-sized electric engine of the electric bicycle of the transmission system is put through a large constant load. Based on this fact, we not only provide a specific electric bike chain, but provide sprocket for Bosch motor and internal gear hub.
Our chains are ideal for electric powered bikes with narrow tolerances, high-end components and excellent corrosion resistance.
Electric bicycles with gearboxes ought to be equipped with high-end drive sprocketes because the wear 
on the sprocket and chain is usually interdependent. It really is obvious that the quality of the sprocket and the chain should match.
