It has been said[according to whom?] that the advent of the unicycle stems from the popularity of the penny-farthing (or "Ordinary") during the late 19th century. Since the pedal and cranks were connected directly to the front axle, the rear wheel would go up in the air and the rider would be moved slightly forward. Penny-farthing owners discovered they could dispense with the frame and just ride the front wheel and handlebars. The evidence for this theory of unicycle development can reportedly be found in pictures from the late 19th century showing unicycles with large wheels.
Unicycle design has developed since the advent of the first unicycle into many variations including: the seatless unicycle ("ultimate wheel") and the tall ("giraffe") unicycle. During the late 1980s some extreme sportsmen took an interest in the unicycle and modified unicycles to enable them to engage in off-road or mountain unicycling, trials unicycling and street unicycling.
Unicycles compared to other pedal powered vehicles
Bicycles, Tricycles and Quadracycles 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 proficent 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 lack brakes, gears, and the ability to freewheel.
Unicycles have a few key parts:
- The wheel (which includes the tire, tube, rim, spokes, hub and axle)
- The cranks
- Fork-style frame
- Saddle (the seat of the unicycle)
The wheel is usually similar to a small bicycle wheel 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 direct drive). The frame sits on top of the axle bearings, while the cranks attach to the ends of the axle, and the seatpost slides into the frame to allow the saddle to be height adjusted.
Types of unicycles
Types of unicycle include:
Each type has special components unique to that type of unicycle.
Generally used for flatland skills and freestyle routines. Usually 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 20 inches (510 mm), but smaller riders may use 16-or-12-inch (410 or 300 mm) unicycles. Some people prefer 24-inch (610 mm) wheels.
Designed for unicycle trials, 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, 19- or 20-inch (510 mm) knobby tires to absorb some of the impact on drops.
Mountain Unicycles ("MUnis")
"MUni" or "muni" is an abbreviation for mountain unicycling. MUnis have many of the same components as trials unicycles, but have a few key differences. Usually, the tire diameters on mountain unicycles are either 24 or 26 inches (660 mm), allowing the rider to more easily roll over obstacles such as roots and rocks. 29 inch munis are also used but are usually used for longer trips, or just a challenge. The seat is also thicker and more comfortable on MUnis to compensate for the rough terrain. Brakes are used for steep descents.
Used for long distances, these unicycles are specially made to cover distances. They have a large wheel diameter, between 26 and 36 in., so more distance is covered in less pedal rotation. A 36" 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.
- Giraffe: a chain-driven unicycle. use of a chain 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 3 feet to over 10 feet high.
- Geared unicycle ("GUni"): a unicycle whose wheel rotates faster than the pedal cadence. They are used for distance riding and racing.
- Multi-wheeled unicycle: a unicycle with more than one wheel, stacked on top of each other so that only one wheel touches the ground (nicknamed stacks). The wheels are linked together by chains or direct contact with each other.
- Kangaroo unicycle: a unicycle that has both the cranks facing in the same direction. They are so named due to the hopping motion of the rider's legs, supposedly resembling the jumping of a kangaroo.
- Eccentric unicycle: a unicycle that has the hub off-center in the wheel. Putting an eccentric wheel on a kangaroo unicycle can make riding easier, and the rider's motion appear more kangaroo-like.
- Ultimate wheel: a unicycle with no frame or seat, just a wheel and pedals.
- Impossible wheel (BC wheel): a wheel with pegs or metal plates connected to the axle for the rider to stand on. These wheels are for coasting and jumping. A purist form of unicycle, without cranks.
- Monocycle (or monowheel): a large wheel inside which the rider sits (as in a hamster wheel), either motorized or pedal-powered. The greater gyroscopic properties and lower center of mass make it easier to balance than a normal unicycle but less maneuverable.
- Self-balancing unicycle: a computer-controlled, motor-driven, self-balancing unicycle.
- Freewheeling unicycle: a unicycle in which the hub has a freewheel mechanism, allowing the rider, to coast or move forward without pedaling, as a common bicycle does. These unicycles almost always have brakes because they cannot stop the way traditional unicycles do. The brake lever is generally mounted in the bottom of the saddle. These unicycles also cannot go backwards.
Other variations include:
- hydraulic giraffe
- unibike[clarification needed]
- suicycle[clarification needed]
- motorized unicycle
The pedals of a typical unicycle (e.g. not a giraffe or guni) connect directly to the wheel. This means that there are no gears to shift and provides a very direct feel of the wheel contact with the ground. It also means that wheel size is a major factor in unicycle speeds:
|Wheel size||Avg||High|
|20"||5 mph (8.0 km/h)||9 mph (14 km/h)|
|24"||7 mph (11 km/h)||12 mph (19 km/h)|
|29"||10 mph (16 km/h)||17 mph (27 km/h)|
|36"||11 mph (18 km/h)||28 mph (45 km/h)|
Having training aids may make it easier to become comfortable with riding a unicycle. One method for training is using a spotter to make riding easier. One other easy way to learn is to find 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. If a hallway cannot be found, a fence or clothes line is suitable. Equally, riding back and forth between two chairs, faced back to back, whilst 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 ski poles is generally discouraged as they hinder balance and create dependence. A fall onto props could also cause serious injury.
Traditionally, unicycling has been seen as a circus skill which has been performed at events to entertain the public in the circus or during parades, carnivals 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 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:
- 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
- Along with freestyle it is a performance style of unicycling. Often employed by clowns 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 mountain unicycling (abbreviated to 'MUni')
- Muni is riding on rough terrain and has developed as a form of unicycling in recent years. Any place a mountain bike can go, a mountain unicycle can go as well.
- Touring or commuting
- This style concentrates on distance riding. With a 29-or-36-inch (740 or 910 mm) wheel cruising speeds of 10 to 15 mph (24 km/h) or more can easily be reached.
- As of 2009[update] 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 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 24 inches (610 mm) 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, Detroit, Phoenix, Minneapolis, and Toronto. Switzerland, France, Germany and Puerto Rico are all field teams. The Puerto Rico All Stars has been one of the dominant teams and has won several world championships.
Unicycle hockey follows rules basically similar to ice hockey or inline hockey, using a tennis ball and ice-hockey sticks. Play is mostly non-contact. The sport has active leagues in Germany, Switzerland 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.
Unicycle handball uses a handball-sized ball. The teams aim to throw it into a vertical hoop placed about 6 feet (1.8 m) above the ground It has been played in the Polish village of Chrzelice since late 1970s
Equipment and safety
|This section does not cite any references or sources. (September 2013)|
- Wrist guards
- The most common impact points when falling from a unicycle are the feet (an unexpected dismount), but when falling out of control the hands and wrists are the next most common. Of all the safety gear, wrist guards receive the most wear and tear.
- Knee and elbow pads
- The second most common impact point is the knees, followed by the elbows. Knee pads are required for events like racing and MUni .
- A helmet becomes especially important when partaking in specialty riding such as MUni, and, in some jurisdictions, is required for road riding as well as racing, MUni, and other events. The helmet is helpful against hitting one's head on the ground, trees, and branches.
- Shin guards
- Shin guards become a necessary piece of equipment when using metal or pinned pedals. These types of pedals grip the shoes best, but can cause injury to the legs.
- Cycling shorts
- Padded cycling shorts are designed with a seamless, padded crotch, and long enough legs to extend down past the saddle, making them much more comfortable than "normal" shorts.
- Gloves are required at some unicycling events such as racing. Gloves may be fingerless (but fingerless gloves are not recommended). They are also very useful for protecting the hands in MUni and Trials riding.

UNICON and Eurocycle
UNICON and Eurocycle are regular international unicycling conventions.
The biennial UNICON (International Unicycling Convention), sanctioned by the International Unicycling Federation, comprises all major unicycling disciplines and is a major event on the international unicycling calendar. Events include: artistic (group, pairs, individual, standard skill, open-X), track racing (100 metres, 400 metres, 800 metres, 30 metres walk the wheel, 50 metres one-foot), 10 kilometres, marathon (42.195 km), muni (cross-country, uphill, downhill, North Shore downhill), trials, basketball and hockey.
The Eurocycle (EUROpean uniCYCLE meeting) is a similar convention but based in Europe.
The world's first multi-stage unicycle race, Ride the Lobster, took place in Nova Scotia in June 2008. Some 35 teams from 14 countries competed over a total distance of 800 km. Each team consisted of a maximum of 3 riders and 1 support person.
Unicross, or unicycle cyclocross is an emerging race format in which unicycles race over a cyclocross course.
