Why do bikes have so many gears when a car only has 5 or 6? Does one need that many gears on a bike?
How do different gears affect the pedaling cadence?
When you switch to a lower gear, your pedaling cadence increases, but your pedaling effort decreases. Conversely, when you switch to a higher gear, your pedaling cadence decreases, but your pedaling effort increases. By selecting the appropriate gear, cyclists can maintain an optimal pedaling cadence, which increases efficiency and reduces fatigue.
