A unicycle is a cycling vehicle with a single wheel. The unicycle invention dates back to the late 19th century. The most well-known variety of unicycles has an edge with a seat, and is pedal-driven (human-fueled, immediate drive). Most of the time, unicycling has been seen as a carnival event which has been performed at occasions to entertain the general audience in some bazaars or some parades, festivals or road celebrations. There are many variations to a unicycle to suit various sports: Freestyle unicycles, Trials unicycles, Mountain unicycles, Giraffe unicycles, and Long separation unicycles. Other unicycling variations include the high jump and the long jump.
