Road cycling is the most widespread form of cycling. It includes recreational, racing, and utility cycling. Road cyclists are generally expected to obey the same rules and laws as other vehicle drivers or riders and may also be vehicular cyclists.

Dedicated road bicycles have drop handlebars and multiple gears, although there are single and fixed gear varieties. Road bikes also use narrow, high-pressure tires to decrease rolling resistance, and tend to be somewhat lighter than other types of bicycle. The drop handlebars are often positioned lower than the saddle in order to put the rider in a more aerodynamic position. In an effort to become more aerodynamic, some riders have begun using aero bars.
