A Freestyle unicycle refers to Freestyle Unicycling which is probably the original form of extreme unicycling. It is based on performance and is carried out in hall or gymnasium, often to music. Freestyle unicycling is often compared to figure skating. Freestyle competitions are held around the world and the world championships UNICON are held every 2 years.

Freestyle unicycles are also the most common unicycle used to learn on. These vary in size from 12″ up to 24″; the most common size for learning on is the 20″. Learner unicycles tend to have longer cranks than competition freestyle unicycles, this is to help with stability.
