Dirt jumping

Additionally, the goal is not to complete the course with the fastest time, but rather to perform the tricks with the style.

There is only one standard BMX dirt jumping bike frame, which is meant to fit all riders, young and old.

An 'all-round' bike used for dirt jumping will more likely have 26-inch wheels, a 25-36 tooth chainring with a wide-ratio cassette and a short- to mid-travel fork.
