BMX, an abbreviation for bicycle motocross or bike motocross, is a cycle sport performed on BMX bikes, either in competitive BMX racing or freestyle BMX, or else in general street or off-road recreation.
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.
Cycle sport is competitive physical activity using bicycles. There are several categories of bicycle racing including road bicycle racing, cyclo-cross, mountain bike racing, track cycling, BMX, and cycle speedway. Non-racing cycling sports include artistic cycling, cycle polo, freestyle BMX, mountain bike trials, hardcourt bike polo and cycleball. The Union Cycliste Internationale (UCI) is the world governing body for cycling and international competitive cycling events. The International Human Powered Vehicle Association is the governing body for human-powered vehicles that imposes far fewer restrictions on their design than does the UCI. The UltraMarathon Cycling Association is the governing body for many ultra-distance cycling races.
A single-speed bicycle is a type of bicycle with a single gear ratio. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle.
A fixed-gear bicycle is a bicycle that has a drivetrain with no freewheel mechanism such that the pedals always will spin together with the rear wheel. The freewheel was developed early in the history of bicycle design but the fixed-gear bicycle remained the standard track racing design. More recently the "fixie" has become a popular alternative among mainly urban cyclists, offering the advantage of simplicity compared with the standard multi-geared bicycle.
The track stand or standstill is a technique that bicycle riders can use to maintain balance while their bicycle remains stationary or moves only minimal distances. The technique originated in track cycling and is now used by other types of cyclists wishing to stop for a short time without putting a foot on the ground, such as bike commuters at stop signs. To perform a track stand, a cyclist holds the cranks in an approximately horizontal position with the front wheel steered to the left or right, and pedals forward, and back in the case of a fixed-gear bicycle, which the steered front wheel converts into a side-to-side motion.
Bob Haro is an American former professional freestyle BMX rider turned artist and business executive. He is the founder of Haro Bikes and was one of the most important early innovators of BMX freestyle.
Freestyle BMX is bicycle motocross stunt riding on BMX bikes. It is an extreme sport descended from BMX racing that consists of five disciplines: street, park, vert, trails, and flatland. In June 2017, the International Olympic Committee announced that freestyle park was to be added as an Olympic event to the 2020 Summer Olympics.
Flatland is a freestyle BMX riding style performed on smooth flat surfaces that do not include any ramps, jumps, or grindrails. It is sometimes described as a form of artistic cycling with a blend of breakdancing.
Freeride is a discipline of mountain biking closely related to downhill biking, dirt jumping, freestyle motocross, and freestyle BMX. When riding, a freerider one focuses on tricks, style, and technical trail features.
Dirt jumping is the practice of riding bikes over jumps made of dirt or soil and becoming airborne. Dirt jumping evolved alongside BMX racing and is similar to BMX or mountain bike racing in that the rider jumps off of mounds of dirt, usually performing a midair trick in between. It differs in that the jumps are usually much larger and designed to lift the rider higher into the air. Additionally, the goal is not to complete the course with the fastest time, but rather to perform the tricks with the style. Dirt jumping can be performed on BMX bikes or specialized mountain bikes known simply as "dirt jumpers".
Flip-flop hubs, also called double-sided hubs, are rear bicycle hubs that are threaded to accept fixed cogs and/or freewheels on both sides.
A BMX bike is a bicycle used for cycle sport, specifically racing or stunt riding. BMX stands for bicycle motocross.
Edward Lynn "Eddie" Fiola is an American former professional freestyle BMX rider, and a film stuntman.
Craig Campbell is a retired British freestyle BMX rider and disc jockey.
Michael Chacon is a professional fixed-gear bicycle rider. He is ranked among the top fixed freestyle riders in the world. Chacon started riding fixed gear bikes in his hometown of Culver City, CA in 2009. Before turning professional, Chacon gained a local following performing freestyle tricks along the boardwalk of Venice Beach, CA. Since his pro debut in February 2010 he has won and placed in fixed gear competitions internationally.
Mountain bike trials, also known as observed trials, is a discipline of mountain biking in which the rider attempts to pass through an obstacle course without setting foot to ground. Derived from motorcycle trials, it originated in Catalonia, Spain as trialsín and is said to have been invented by Pere Pi, the father of Ot Pi, a world champion motorcycle trials rider. Pi's father had wanted his son to learn motorcycle trials by practicing on an ordinary bicycle.
Robert Lewis Osborn is a BMX rider. His father Bob Osborn started BMX Action magazine. He, along with Mike Buff and Bob Haro are considered the forefathers of BMX freestyle, a style of BMX bike riding that involves flatland and ramp tricks.
