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 unicycling. 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 mountain unicycling, an activity similar to mountain biking or trials. History US patents for single-wheeled 'velocipedes' were published in 1869 by Frederick Myers and in 1881 by Battista Scuri. Unicycle design has developed since the Penny Farthing and later 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 o ...

Trials Unicycling
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 riding, bike trials and Motorcycle trial, 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. Jumping is a similar to hopping, except that the unicycle seat is held in front of the rider to allow greater height to be achieved. Pedal grabs and crank grabs involve a hop or jump to land the unicycles Bicycle pedal, pedal or crank (mechanism), crank on the edge of an object, and ...

Unicycle Hockey
Unicycle hockey is a team sport, similar to rink hockey where players try to hit the ball with their sticks into the other team's goal, except that each player must be mounted on a unicycle to play the ball. A team is composed of five players (plus substitutes), but there is no dedicated goalkeeper role (although one player usually stays back in that position). The governing body for unicycle hockey is the International Unicycling Federation which publishes the rules for all unicycle sports. The most recent set of rules for unicycle hockey was published in 2015. 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 players can go behind them, similarly to ice hockey. 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 and a tennis ball is ...

Mountain Unicycling
Mountain unicycling is an adventure sport that consists of traversing rough terrain on a unicycle. Mountain unicycling (muni) is undertaken on similar terrain to mountain biking. However, muni requires much more attention to the microfeatures of the short distance in front of the wheel.The Essential Guide to Mountain and Trials Unicycling, Kris Holm, p128, Unicycles' lack of a freewheel means that descents must be controlled all the way, and the typical lack of a gear system (though two-gear hubs are available) prevents the rider from reaching high speeds. Muni usually takes place on specially designed unicycles, which are equipped with strong hubs, large, knobbly tires, high-grip pedals and rugged frames. Some are also equipped with rim or disc brakes, having the lever mounted under the nose of the saddle. The brake primarily helps to compensate the downhill-slope force, while more expert riders also use it to decelerate or stop. Muni riders also need a few additional s ...

Torker Unicycle
Torker was a brand of bicycles and unicycles owned by Seattle Bike Supply, headquartered in Kent, Washington. History The Torker name was created by Johnson Engineering in Fullerton, CA in 1977 for a BMX bike frame. The first Haro bikes were made by Torker. In 1982, Torker let go Bob Haro when he introduced his own line of BMX racing pants. In 1984, the Torker Bicycle Company went bankrupt, and Seattle Bike Supply purchased the name. BMX bikes with the Torker name were made from the late 1970s into the 2000s. Torker's product line expanded to include beach cruisers, tandem bikes and even unicycles. ''Reader's Digest'' nominated Torker unicycles as "America's 100 Best" for 2006, and Torker was awarded BEST OF 2006 in the December issue of ''Seattle Magazine''. Seattle Bike Supply was acquired by Accell in 2006. BMX team Torker sponsored a BMX racing team that included such riders as: * Kevin McNeal *Leo Green * Mike Miranda * Richie Anderson * Tommy Brackens *Clint Miller ...

Crankset
The crankset (in the US) or chainset (in the UK), is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called ''chainrings'' or ''chainwheels'' attached to the '' cranks'', ''arms'', or ''crankarms'' to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain. Parts Cranks The two ''cranks'', one on each side and usually mounted 180° apart, connect the bottom bracket axle to the pedals. Lengths Bicycle cranks can vary in length to accommodate different sized riders and different types of cycling. Crank length is measured from the center of the pedal spindle to the center of the bottom bracket spindle or axle. The larger bicycle component manufacturers typically of ...

Ultimate Wheel
The impossible wheel, also known as the BC wheel (after the comic strip B.C.), represents the most basic type of unicycle, consisting of a single, spoked wheel with pegs extending from the axle. The rider mounts the wheel by jumping onto the pegs while in motion or by putting one foot onto one plate or peg and pushing along like a skateboard. This device has no drivetrain, so when forward inertia runs out due to gravity and friction, the ride ends. Newer BC wheels use plates which hang below the axle instead of pegs in line with the axle. This makes them easier to ride since the center of gravity is lower. The unicycling community favors the term ''BC wheel'' because the device is not actually impossible to ride; proficiency can be gained with a few hours of practice. Tricks, such as hopping, drops, grinds, and spins, are possible. Ultimate wheel An ultimate wheel is a wheel with two pedals directly connected – similar to a unicycle and impossible wheel. It has no sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Tire
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically, the second largest source, after wind resistance (air drag), of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle. Bicycle tires are also used on unicycles, tricycles, quadracycles, tandem bicycles, hand cycles, bicycle trailers, and trailer bikes. History The first bicycle "tires" were iron bands on the wooden wheels of velocipedes. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Performance
Street performance or busking is the act of performing in public places for gratuities. In many countries, the rewards are generally in the form of money but other gratuities such as food, drink or gifts may be given. Street performance is practiced all over the world and dates back to antiquity. People engaging in this practice are called street performers or buskers in the United Kingdom. Outside of New York, ''buskers'' is not a term generally used in American English. Performances are anything that people find entertaining, including acrobatics, animal tricks, balloon twisting, caricatures, clowning, comedy, contortions, escapology, dance, singing, fire skills, flea circus, fortune-telling, juggling, magic, mime, living statue, musical performance, one man band, puppeteering, snake charming, storytelling or reciting poetry or prose, street art such as sketching and painting, street theatre, sword swallowing, ventriloquism and washboarding. Buskers may be s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Unicycling
''Street unicycling'' is one of the latest developments in unicycling. The aim of the sport is to use natural/urban/specially made obstacles such as ledges, handrails and stairs in a given area to perform tricks that look good. The emphasis falls on technical proficiency, style and creativity. Street unicycling draws inspiration from skateboarding and bmx bike riding, with many similar tricks. For street unicycling, most riders prefer to ride 20" trials unicycles because of their light weight, good hopping abilities, smooth maneuverability. However, some riders prefer using the less conventional 24" and 26" wheel sizes for street riding. Competition street unicycling The 13th Unicycle World Championships (Jul/Aug 2006) played host to the first ever "official" Street Freestyle Competition, while the first ever street competition was truly at the California Mountain Unicycle Weekend in 2004 (http://www.unicycling.com/muni/2004/). Xavier Collos (France) clinched the world title. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circus
A circus is a company of performers who put on diverse entertainment shows that may include clowns, acrobats, trained animals, trapeze acts, musicians, dancers, hoopers, tightrope walkers, jugglers, magicians, ventriloquists, and unicyclists as well as other object manipulation and stunt-oriented artists. The term ''circus'' also describes the performance which has followed various formats through its 250-year modern history. Although not the inventor of the medium, Philip Astley is credited as the father of the modern circus. In 1768, Astley, a skilled equestrian, began performing exhibitions of trick horse riding in an open field called Ha'Penny Hatch on the south side of the Thames River, England. In 1770, he hired acrobats, tightrope walkers, jugglers and a clown to fill in the pauses between the equestrian demonstrations and thus chanced on the format which was later named a "circus". Performances developed significantly over the next fifty years, with large-scale theat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Pedal
The pedal is the part of a bicycle that the rider pushes with their foot to propel the vehicle. It provides the connection between the cyclist's foot or shoe and the crank allowing the leg to turn the bottom bracket spindle and propel the bicycle's wheels. A pedal usually consists of a spindle that threads into the end of the crank, and a body on which the foot rest is attached, that is free to rotate on bearings with respect to the spindle. Pedals were initially attached to cranks connecting directly to the driven (usually front) wheel. The safety bicycle, as it is known today, came into being when the pedals were attached to a crank driving a sprocket that transmitted power to the driven wheel by means of a roller chain. Types Just as bicycles come in many varieties, there are different types of pedals to support different types of cycling. Flat and platform Traditionally, platform pedals were pedals with a relatively large flat area for the foot to rest on, in contrast ...
