Pedals are mechanical devices used to control various types of machinery, most commonly found on bicycles. They are typically attached to a crankset and allow the rider to apply force with their feet to propel the bike forward. The motion of the pedals is transferred to the bike's chain and gears, enabling movement. In addition to bicycles, pedals are also used in musical instruments, such as pianos and organs. These pedals can modify sound, sustain notes, or control volume, enhancing the musician's ability to express themselves. Overall, pedals play a crucial role in both transportation and music.
