Description

Technical field The invention relates to a continuously variable transmission for muscle-powered vehicles, such as bicycles. State of the art Continuously variable transmissions (CVTs) are rotary transmissions where the gear ratio is continuously adjustable. CVTs for bicycles offer seamless and continuous gear ratio changes without the rider having to shift between individual gears. Unlike conventional fixed-gear transmissions, CVTs allow for precise adjustment of the gear ratio to individual needs and riding conditions. Although CVTs for bicycles have made significant progress, some challenges remain. One of the main problems lies in the complexity of the mechanics and the fine-tuning of the gear ratios. The precise and reliable operation of CVT systems requires high-quality components and careful adjustment.Furthermore, many of these transmission systems are relatively heavy and bulky, which increases the bike's weight and can negatively impact handling. Another issue concerns the limited selection of continuously variable transmissions (CVTs) on the market. Although availability has improved, the range is still limited, and finding the right CVT system to meet individual needs can be challenging.
