What are the different bike parts and their functions?

Bikes have several key parts that work together to make them function properly. The frame provides structure and support, while the wheels and tires allow the bike to move. The handlebars steer the bike, and the brakes help to stop it. The gears and chain help to propel the bike forward, and the saddle provides a comfortable seat for the rider. Each part plays a crucial role in the overall performance of the bike.
