Fixed-gear cycling involves riding a bicycle with a single gear that is directly connected to the pedals. This means that when the bike is in motion, the pedals always turn with the wheels. Riders cannot coast; if the bike is moving, they must keep pedaling. This design offers a simple and lightweight bike, often favored for urban commuting. Many fixed-gear bikes are popular among cyclists for their minimalistic style and ease of maintenance. They are commonly used in track cycling and by enthusiasts who enjoy the challenge of controlling speed and momentum without the aid of gears or brakes.
