share (with minor variations) several basic parts including wheels, pedals, cranks, forks, and the saddle with unicycles. Without a rider, unicycles lack stability – however, a proficient unicyclist is usually more stable than a similarly proficient rider on a bicycle as the wheel is not constrained by the linear axis of a frame. Unicycles usually, but not always, lack brakes, gears, and the ability to

with a special hub designed so the axle is a fixed part of the hub. This means the rotation of the cranks directly controls the rotation of the wheel (called

Types of unicycles

Mountain unicycles 1448609405 be860b9a3d

Types of unicycle include: * Freestyle unicycles * Trials unicycles * Mountain unicycles (also called Munis) * Giraffe unicycles * Commuter unicycles * Street unicycles * Cruiser unicycles * Road unicycles Each type has many combinations of frame strength, wheel diameter, and crank length.

Freestyle unicycles

Generally used for flatland skills and freestyle routines, freestyle unicycles typically have a relatively high seatpost, a narrow saddle, and a squared fork (used for one-footed tricks). These unicycles are used similarly to flatland bicycles. Wheel size is usually , but smaller riders may use unicycles. Some people prefer wheels. Many freestyle unicyclists will use white tires to avoid tire marks when riding indoors.

Trials unicycles

Designed for

unicycle trials Unicycle trials is a form of unicycling which involves participants attempting to ride a unicycle over obstacles without any part of the rider touching the ground. The obstacles traversed can be set up specifically for the purpose of unicycle tri ...

, these unicycles are stronger than standard unicycles in order to withstand the stresses caused by jumping, dropping, and supporting the weight of the unicycle and rider on components such as the pedals and cranks. Many trials unicycles also have wide, knobby tires to absorb some of the impact on drops.

Mountain unicycles ("Munis")

Mountain unicycling Mountain unicycling is an adventure sport that consists of traversing rough terrain on a unicycle. Mountain unicycling (muni or municycling) is undertaken on similar terrain to mountain biking. However, muni requires much more attention to th ...

(abbreviated to muni or mUni) consists of riding specialized unicycles on mountain bike trails or otherwise off-roading. Mountain unicycles have thicker, wider tires for better traction. Riders may occasionally lower air pressure for increased shock absorption. Many riders choose to use long cranks to increase power when riding up hills and over rough terrain. A disc brake is sometimes used for descents; the brake handle is attached to the underside of the handle on the front of the saddle.

Touring/commuter unicycles

Used for long distances, these unicycles are specially made to cover distances. They have a large wheel diameter, between , so more distance is covered in less pedal rotation. A unicycle made by the Coker Tire company started the big wheel trend. Some variations on the traditional touring unicycle include the Schlumpf "GUni" (geared unicycle), which uses a two-speed internal fixed-geared hub. Larger direct-drive wheels tend to have shorter cranks to allow for easier cadence and more speed. Geared wheels, with an effective diameter larger than the wheel itself, tend to use longer cranks to increase torque as they are not required to achieve such high cadences as direct-drive wheels, but demand greater force per pedal stroke.

Other variations

* Giraffe, a chain-driven unicycle. Use of a chain or multiple wheels in a gear-like configuration can make the unicycle much taller than standard unicycles (note that multi-wheel unicycles can be described as ''giraffes''). Standard unicycles don't have a chain, which limits the seat height based on how long the rider's legs are, because there the crank is attached directly to the wheel axle. Giraffe unicycles can range in heights from . * Geared unicycle, or GUni, a unicycle whose wheel rotates faster than the pedal

Training aids

Training aids are sometimes used to make it easier to become comfortable with riding a unicycle. One method for training is using a spotter to make riding easier. Another method is finding a narrow hallway that can be used to help alleviate left and right balancing while allowing a beginner to focus on forward and backward balance. Equally, riding back and forth between two chairs, faced back to back, while holding on to the chair backs allows the user to gauge how to appropriately position oneself before setting off. Using props such as sticks or

or street festivals. Recent developments in the strength and durability of bicycle (and consequently unicycle) parts have given rise to many new activities including trials of unicycling and mountain unicycling. Unicycling is arguably now as much a competitive sport and recreational pursuit as an entertainment activity. The principal types of unicycling are: ; Freestyle: Perhaps the oldest form of unicycling, traditional freestyle riding is based on performance. Freestyle tricks and moves are derived from different ways of riding the unicycle, and linking these moves together into one long flowing line that is aesthetically pleasing. Competitions look very similar to figure skating, with riders performing routines to music. ; Comedy: Along with freestyle it is a performance style of unicycling. Often employed by

clowns A clown is a person who performs physical comedy and arts in an Improvisational theatre#Comedy, open-ended fashion, typically while wearing distinct cosmetics, makeup or costume, costuming and reversing social norm, folkway-norms. The art of ...

and other circus skills performers. Comedy unicycling exaggerates the perceived difficulty of riding a unicycle to create a comedic performance. ; Trials unicycling: Trials unicycling is specifically aimed at negotiating obstacles. Analogous to trials bike riding. ; Street unicycling: Street unicycling as a style involves riders using a combination of objects found in urbanized settings (such as ledges, handrails, and stairs) to perform a wide variety of tricks. Many tricks are similar to those performed in other extreme sports, such as BMX and skateboarding. ; Off-road or

(abbreviated to 'MUni'): Muni is riding on rough terrain and has developed as a form of unicycling in recent years. ; Touring or commuting: This style concentrates on distance riding. With a wheel cruising speeds of or more can easily be reached. ; Flatland unicycling: This style of unicycling is similar to freestyle in that various tricks and movements are performed on flat ground. Flatland, however, does not have the performance element of freestyle, but instead has tricks that are similar to those in BMX and skateboarding.

Unicycle team sports

Unicycling is also performed as a team sport.

Unicycle basketball

Unicycle basketball uses a regulation basketball on a regular basketball court with the same rules, e.g., one must dribble the ball while riding. There are a number of rules that are particular to unicycle basketball as well, e.g., a player must be mounted on the unicycle when in-bounding the ball. Unicycle basketball is usually played using or smaller unicycles, and using plastic pedals, both to preserve the court and the players' shins. In North America, regular unicycle basketball games are organized in Berkeley, San Luis Obispo, Detroit, Phoenix, Minneapolis, and Toronto. Switzerland, France, Germany and Puerto Rico are all field teams. The Puerto Rico All Star Unicycling Basketball Team has been one of the dominant teams and has won several world championships.

, using a tennis ball and ice-hockey sticks. Play is mostly non-contact. The sport has active leagues in Germany, Switzerland, Australia and the UK and international tournaments held at least bi-annually. Tournaments in the UK are held by various teams across the country usually in sports halls, but occasionally outside. Each tournament lasts a day and around 8 teams normally compete in a round-robin league with the winner being whoever has the most points. If two teams have the same number of points the winner can be decided by goal difference or a penalty shoot-out.
