What are the advantages of bicycle transmissions?

1. Change the gear ratio: The gear ratio of the bicycle can be changed through the transmission, allowing the rider to choose a suitable gear ratio according to road conditions and physical strength, and easily cope with different road conditions and slopes.

2. Improve riding efficiency: Reasonable selection of gear ratios can improve riding efficiency and reduce physical exertion during riding. On a flat road, you can select a high gear to maintain high speed; when climbing a hill, you can select a low gear to increase torque.

3. Increase comfort: The transmission can provide a suitable frequency of riding, allowing the rider to maintain a comfortable cadence range. When riding at high speed, choose an appropriate high-speed gear to reduce your cadence; when climbing a hill, choose an appropriate low-speed gear to maintain an appropriate cadence.

4. Adapt to different road conditions: The transmission allows the rider to adjust according to different road conditions. For example, on a bumpy mountain ride, a lower gear can be selected to increase torque, providing better climbing ability and control.

5. Improve safety: The transmission can quickly change speed during riding, allowing the rider to flexibly respond to emergencies and improve controllability and safety.

In general, bicycle transmissions can flexibly adjust the gear ratio according to the needs of the rider and road conditions, improving riding efficiency, comfort and safety. This makes riding easier, smoother and more enjoyable.
