What Is Chainless Transmission?

The belt-driven transmission is a new type of bicycle transmission system that has higher efficiency, smoother transmission, and lower maintenance requirements than the conventional chain-driven system.

The belt-driven transmission replaces the chain with a belt that is driven by a pulley on both ends of the transmission axle. The belt is equipped with teeth that fit into grooves in the pulley, and the sprocket is mounted on the rear wheel. When the rider pedals, the pulleys on the transmission axle rotate at a certain angle, causing the teeth on the belt to move along the grooves in the pulley, and thus transferring the power to the sprocket. The sprocket then transmits the power to the rear wheel through the hub, propelling the bicycle forward.

Compared to the traditional chain-driven system, the belt-driven transmission has the following advantages: higher transmission efficiency, smoother transmission, less maintenance requirements, and longer lifespan. The belt-driven transmission is also designed to be lighter and more simple, effectively reducing the overall weight of the bicycle and increasing the riding comfort and convenience.
