A bike, short for bicycle, is a two-wheeled vehicle powered by pedaling. It consists of a frame, wheels, handlebars, a seat, and pedals. The rider uses the handlebars to steer and the pedals to propel the bike forward. Bikes can vary in design depending on their intended use, such as road bikes for speed, mountain bikes for off-road terrain, or hybrid bikes for general use. Some bikes also feature gears to adjust resistance and speed. They are a popular mode of transportation, exercise, and recreation due to their efficiency, environmental benefits, and versatility.
