A road bike is a type of bicycle designed specifically for riding on paved roads. It features lightweight frames, thin tires, and a more aerodynamic riding position, which helps cyclists achieve higher speeds. Road bikes are commonly used for racing, long-distance rides, and fitness purposes. These bikes typically have drop handlebars, allowing for multiple hand positions and better aerodynamics. They often come with multiple gears to help riders tackle various terrains. Popular brands of road bikes include Trek, Specialized, and Giant, each offering a range of models to suit different skill levels and preferences.
