Have you ever ridden on a unicycle, with only one wheel?

Unicycle
A unicycle is a vehicle that touches the ground with only one wheel. The most common variation has a frame with a saddle, and has a pedal-driven direct drive. A two speed hub is commercially available for faster uncycling. Unicycling is practiced professionally in circuses, by street performers, in festivals, and as a hobby. Unicycles have also been used to create new sports such as unicycle hockey. In recent years, unicycles have also been used in activities similar to mountain biking or trials. US patents for single-wheeled 'velocipedes' were published in 1869 by Frederick Myers and in 1881 by Battista Scuri.
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 trials, but are often walls, railings, ledges and other "street furniture" found in an urban environment. The sport is derived from (or at least inspired by) bike trials and motorcycle trials. Obstacles are traversed using various moves. Hopping is achieved by suddenly forcing the unicycle pedals downwards while holding the seat, the reactive forces resulting from the compression of the tyre lift the unicycle into the air.
Dustin Kelm
Dustin Kelm is a world champion and world record setting unicyclist. He has performed and competed throughout North, South and Central America, Europe, Asia, Africa and the Caribbean. Dustin is a three time Unicycling Society of America expert freestyle national champion, a Unicycling Society of America mountain unicycling national champion and a UNICON freestyle World Champion. He was born January 26, 1972 and was given his first unicycle at the age of 10. Two years later he joined the Twin Cities Unicycle Club in Minneapolis and discovered there was much more he could do on a unicycle besides his paper route.
Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both roadholding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear.
Limited-slip differential
A limited-slip differential is a type of differential that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. In an automobile, such limited-slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity. In 1932, Ferdinand Porsche designed a Grand Prix racing car for the Auto Union company. The high power of the design caused one of the rear wheels to experience excessive wheel spin at any speed up to . In 1935, Porsche commissioned the engineering firm ZF to design a limited-slip differential to improve performance.
Kris Holm
Kris Holm (born July 15, 1973) is a Canadian best known for riding a unicycle in off-road conditions. He has ridden since 1985 and is considered one of the pioneers of off-road unicycling, and is the world's best-known unicyclist. He is the founder of competitive unicycle trials (unicycle obstacle riding) and was the 1999 North American, 2002 World, and 2005 European unicycle trials champion. He also held the unicycle sidehop world record from 1998-2004 (since broken), and performed trials demonstrations with the Norco Factory Trials Team from 1998-2006. Holm first received a unicycle for his twelfth birthday, in 1985.
Monowheel
A monowheel is a one-wheeled single-track vehicle similar to a unicycle. Instead of sitting above the wheel as in a unicycle, the rider sits either within the wheel or next to it. The wheel is a ring, usually driven by smaller wheels pressing against its inner rim. Most are single-passenger vehicles, though multi-passenger models have been built. Hand-cranked and pedal-powered monowheels were patented and built in the late 19th century; most built in the 20th century have been motorized. Some modern builders refer to these vehicles as monocycles, though that term is also sometimes used to describe motorized unicycles.

I haven't I once had a friend who did that though!
