A road bike is a type of bicycle designed specifically for riding on paved roads. It is characterized by its lightweight frame, narrow tires, and drop handlebars, which allow the rider to adopt an aerodynamic position for increased speed and efficiency. Road bikes are built for fast-paced cycling and are commonly used in racing, group rides, and long-distance endurance events. They typically feature multiple gears for various terrains and offer a smooth and efficient ride on the open road.
