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 on- or off-road recreation. BMX began in the 1970s when young cyclists appropriated motocross tracks for recreational purposes and stunting, eventually evolving into specialized BMX bikes and competitions.
Mountain biking is a sport of riding bicycles off-road, often over rough terrain, usually using specially designed mountain bikes. Mountain bikes share similarities with other bikes but incorporate features designed to enhance durability and performance in rough terrain, such as air or coil-sprung shocks used as suspension, larger and wider wheels and tires, stronger frame materials, and mechanically or hydraulically actuated disc brakes. Mountain biking can generally be broken down into five distinct categories: cross country, trail riding, all mountain, downhill, and freeride.
A longboard is a type of skateboard typified by longer decks and wheelbases, larger-diameter and softer (lower-durometer) wheels, and often lower riding height compared to street skateboards, though there is wide variation in the geometry and construction of longboards. Among the earliest types of skateboards, longboards were inspired by surfing, with early longboards drawing from the design of surfboards, resembling and mimicking the motion of riding a surfboard, but adapted to riding on streets in a practice known as sidewalk surfing.
Longboarding is typically defined as a variation of skateboarding that involves a larger than usual board and softer urethane wheels. Longboards vary in shape and size. Compared to skateboards, longboards are more stable at speed and have more traction, due to larger wheel size and lower wheel durometers. A standard skateboard is typically between 28-34 inches long, whereas a longboard may exceed upwards of 50 inches long. Modern downhill race boards however are typically between 30-35 inches in length, making them more comparable to the length of a traditional skateboard. Any longboards use trucks (axles) that have different geometric parameters than skateboards. The skateboards use "traditional kingpin trucks" while longboards often use "reverse kingpin trucks." This hardware change is the key element in the increased stability that longboards offer.
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 and mountain bike trials. 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.
Road bicycle racing is the cycle sport discipline of road cycling, held primarily on paved roads. Road racing is the most popular professional form of bicycle racing, in terms of numbers of competitors, events and spectators. The two most common competition formats are mass start events, where riders start simultaneously and race to a set finish point; and time trials, where individual riders or teams race a course alone against the clock. Stage races or "tours" take multiple days, and consist of several mass-start or time-trial stages ridden consecutively.
Downhill mountain biking (DH) is a style of mountain biking practiced on steep, rough terrain that often features jumps, drops, rock gardens and other obstacles. Jumps can be up to and including 12 meters, and drops can be greater than 3 meters.
Dirtsurfing is the sport of riding a Dirtsurfer brand inline board. This new Australian boardsport is correctly known as inline boarding because Dirtsurfer is a trademark protected brand name.
A gravity racer or soapbox is a motorless vehicle which is raced on a downhill road either against the clock or against another competitor. Although most are built for the purpose of recreation, some gravity racing teams take the sport more seriously and compete to win. They are propelled by gravity and can achieve speeds upwards of 164 km/h.
The Gravity Games was a multi-sport competition originating in Providence, Rhode Island that was broken down into Winter and Summer adaptations. The competition featured a variety of extreme sports such as aggressive inline skating, skateboarding, freestyle motocross, BMX freestyle and snowboarding.
Mountain bike racing is the competitive cycle sport discipline of mountain biking held on off-road terrain. The Union Cycliste Internationale (UCI) recognised the discipline relatively late in 1990, when it sanctioned the world championships in Durango, Colorado. The first UCI Mountain Bike World Cup series took place in 1988. Its nine-race circuit covered two continents—Europe and North America—and was sponsored by Grundig. Cross-country racing was the only World Cup sport at this time. In 1993, a six-event downhill World Cup was introduced. In 1996, cross-country mountain biking events were added to the Olympic Games. In 2006, cross-country mountain biking events became part of the World Deaf Cycling Championships for the first time in San Francisco, USA.
Scot Alexander Breithaupt was an entrepreneur, "Old School" professional motorcycle MX and bicycle motocross (BMX) racer and a founding father of BMX in 1970 whose prime competitive years were from 1970 to 1984. Many consider him, in some ways, a founder of "Old School BMX"—an era from roughly 1969 to 1987 or 1988, from its very beginnings to just after its first major slump in popularity from 1985 to 1988. Racing started to rise in participation again around 1988–89 and is considered the start of Mid School BMX, roughly 1988–2000. He was born in Long Beach, California.
Roller sports are sports that use human powered vehicles which use rolling either by gravity or various pushing techniques. Typically ball bearings and polyurethane wheels are used for momentum and traction respectively, and attached to devices or vehicles that the roller puts his weight on. The international governing body is World Skate.
Motorcycle racing is the motorcycle sport of racing motorcycles. Major varieties include motorcycle road racing and off-road racing, both either on circuits or open courses, and track racing. Other categories include hill climbs, drag racing and land speed record trials.
A skateboard style refers to the way a skateboarder prefers to ride a skateboard. Skateboard styles can be broadly divided into two different categories: skateboarding to perform tricks and skateboarding as a means of transportation. Styles of skateboarding have evolved over time and are influenced by a number of factors including sociocultural evolution, mass media, music, technology, corporate influence and individual skill level.
Slalom skateboarding is a form of downhill skateboard racing that first appeared in the 1960s and 1970s and has made a resurgence in popularity in the 2000s. Slalom racers skate down a course usually marked by plastic cones. The racer tries to get through the course with the fastest time, while knocking down the fewest cones. Each cone typically carries a penalty of a fraction of a second which is added to the skater's time.
Snowboard cross, also known as boardercross, is a snowboard competition in which four to six competitors race down a course. Snowboard cross courses are typically quite narrow and include cambered turns, various types of jumps, berms, rollers, drops, steep and flat sections designed to challenge the riders' ability to stay in control while maintaining maximum speed. It is not uncommon for racers to collide with each other mid-race.
Bob Pereyra is the pioneer of the extreme sport of street luge and is one of the fastest street luge racers in the world. He is one of the most recognized street luge racers worldwide. He was the winner of six medals in the extreme X Game championships.
Shovel Racing is a sport practiced in some parts of the United States. It consists of riders racing down a snowy hill riding on a shovel. It has been practiced on both typical snow shovels and modified shovel-based sleds. It was once an event in the winter X games, but was removed due to safety concerns.
Newton's Nation, originally Newton's Playground, is an Australian sports festival since 2008.
