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