    A bicycle consists of several essential parts, each with a specific function. The frame supports the entire structure. The wheels and axles enable smooth movement, while pedals act as levers to generate motion. The chain and sprockets transfer power from pedals to the rear wheel. Brakes slow down or stop the bicycle, ensuring safety. Handlebars help in steering, and the saddle provides seating comfort. Understanding these parts helps maintain and repair a bicycle effectively.
