Unicycle hockey is a team sport, similar to roller or inline hockey, except that each player must be mounted on a unicycle (with both feet on the pedals) to play the ball. A team is composed of five players (plus substitutes), but there is no dedicated goalkeeper role played by some clubs.
The court used is between 35 and 45 metres in length, and 20 to 25 metres wide. It should have either beveled or rounded corners, and barriers on all sides. The goals are also set back from the end walls so that play can go behind them, similarly to ice hockey.
Unicycle hockey can, and is played in all types of indoor courts / gyms, streets, parking lots, tennis courts
Any stick which is legal for ice hockey, other than that of a goalkeeper, can be used. The unicycles can have a maximum wheel diameter of 24 inches (61 cm) which is mostly used by goalies. A 20-inch wheel is preferred by most players, as it allows quick turns, changing directions and fast acceleration.
A tennis ball is typically used in game play, although street hockey balls are also permitted.
There are at least three national unicycle hockey leagues. One is in the UK, with approximately 10 registered teams, another is in Germany, where there are approximately 53 registered teams, and a third is in Switzerland, with approximately 20 teams.
