The mountain unicycle (also called a muni) is a unicycle that has either been constructed or modified for mountain unicycling. Mountain unicycles typically use a 24" or 26" mountain bike or downhill tire, have a handle under the front of the seat, and may also have brakes and suspension to improve their off-road capabilities. Unlike their two-wheeled counterparts, mountain unicycles have only a single gear ratio (that is, fixed wheel) so riders vary their speed by changing their pedalling cadence. To go up steep inclines, riders often hop sideways up the hill. On descents, some riders freewheel their unicycle by using their feet as brakes on the tire, a technique known as gliding.
Today there are hundreds of mountain unicyclists riding all kinds of terrain across the world. The world's best known, Kris Holm, is a Canadian.
Mountainunicycling usually takes place on specially designed unicycles, which are equipped with strong hubs, fat tires and rugged frames for off-road cycling.
Mountainunicycling is a slower-paced sport than mountain bicycling, primarily because the lack of gears makes it impossible to go very fast.
Mountainunicycles typically use a 24" or 26" mountain bike or downhill tire, have a handle under the front of the seat, and may also have brakes and suspension to improve their off-road capabilities.
Mountain Unicylcing is done on a more beefy unicycle then normal, 24"-26" wheels 3" wide are what is usually used, accompanied by a heavy duty frame, cranks, hub and sometimes brakes.
Trials unicycling is usually preformed on a very strong yet light-weight unicycle with a 20"x2.5" tire, however some people prefer to go with a 24" wheel the 20" is most common.
Unicycles such as the KH20 and Onza are specifically designed to put up with the abuse sustained while trials unicycling.
