Artistic cyclingThe handlebar, which can spin 360°, is mounted to a stem that has no horizontal extension, which puts the stem clamp in line with the steering axis and allows for the handlebars to remain in the same relative position no matter whether the front wheel is facing forward or backward. The crank arm length may have a center to center distance of 130 to 170 mm. The riding area for artistic cycling is a wooden court, which also serves cycle ball competitions, that ranges in dimensions from 9 x 12 meters to 11 x 14 meters, where the maximum size is mandated for international competitions. Three concentric circles are taped or painted at the center of the court with diameters (measured to the outside edge of the line) of 0.5, 4, & 8 meters. Artistic cycling is a form of competitive indoor cycling in which athletes perform tricks (called exercises) for points on specialized, fixed-gear bikes in a format similar to ballet or gymnastics.
Two meters is required for international competitions. . The gearing of the chainring and sprocket are run at or near a one to one ratio, but the chainring may not have fewer teeth than the sprocket.
Four half-meter hashes extend radially from the four quadrants of the middle circle. A clear area of 0.5 to 2 meters must be free of all immovable objects around the perimeter of the court. Handlegrips or bar tape are applied to the top, horizontal portions of the bar.
The exercises are performed before judges in six minute rounds by singles, pairs, four- or six-man teams. The first unofficial world championships in artistic cycling was held in 1888 by German-American Nicholas Edward Kaufmann and was largely a publicity stunt to showcase his trick bicycling. The first official world championships were held for men in 1956 and for women in 1970. The bicycles used for artistic cycling are a form of fixed gear bicycle. The wheels must be of equal size and are closely spaced in order to make tricks, such as wheelies, easier to perform. The handlebars are similar in form to a shallow drop handlebar found on a racing bicycle which has been turned upside down.
