A bicycle propelled by an electric motor and employing a belt-and-pulley system for power transmission offers a unique riding experience. This system replaces the traditional chain and sprockets, connecting the motor to the rear wheel via a continuous loop of reinforced material, often carbon fiber or rubber.
This configuration provides several advantages. Quiet operation and reduced maintenance requirements are chief among these, as belts require less lubrication and cleaning than chains. Durability and efficiency also contribute to the growing popularity of this technology. Historically, belt drives have been utilized in various mechanical applications, and their adaptation to electric bicycles represents a significant innovation in personal transportation.
