Bicycle motocross or BMX refers to the sport in which the main goal is extreme racing on bicycles in motocross style on tracks with inline start and expressive obstacles, and it is also the term that refers to the bicycle itself that is designed for dirt and motocross cycling.

BMX started in the early 1970s when children began racing their bicycles on dirt tracks in southern California, drawing inspiration from the motocross superstars of the time. The size and availability of the Schwinn Sting-Ray and other wheelie bikes made them the natural bike of choice, since they were easily customized for better handling and performance. BMX racing was a phenomenon by the mid-1970s. Children were racing standard road bikes off-road, around purpose-built tracks in California. The 1972 motorcycle racing documentary On Any Sunday is generally credited with inspiring the movement nationally in the US; its opening scene shows kids riding their Sting-Rays off-road. By the middle of that decade the sport achieved critical mass, and manufacturers began creating bicycles designed especially for the sport.
