A track bicycle is a type of bicycle specifically designed for racing on a velodrome, which is an oval track with banked sides. Unlike regular bicycles, track bikes have a fixed gear, meaning the pedals are directly connected to the rear wheel, allowing for efficient power transfer. They typically lack brakes, as riders control their speed through pedaling. Track bicycles are lightweight and aerodynamic, featuring a minimalist design to reduce drag. The tires are narrow and smooth, providing maximum grip on the track surface. Events involving track bicycles include sprints, pursuits, and team races, showcasing the speed and skill of the riders.
