A system employing a reinforced belt, rather than a traditional chain, propels this type of bicycle. Typically constructed from carbon fiber or other high-strength polymers, the belt engages toothed sprockets on the crank and rear wheel hub to transfer power. This design distinguishes these bicycles mechanically from their chain-driven counterparts.
This method of power transmission offers several advantages, including reduced maintenance due to the belt’s lack of lubrication requirements and quiet operation. Durability is also a key benefit, as these belts boast significantly longer lifespans than conventional chains. While initially adopted by commuters and touring cyclists for their low-maintenance properties, the technology has seen increasing integration into the mountain biking segment, offering a cleaner and potentially more efficient riding experience.
