Skateboarding is an action sport that involves riding and performing tricks using a skateboard, as well as a recreational activity, an art form, an entertainment industry job, and a method of transportation. Originating in the United States, skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue, with 11.08 million active skateboarders in the world. In 2016, it was announced that skateboarding would be represented at the 2020 Summer Olympics in Tokyo, for both male and female teams.
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work.
Boardsports are active outdoor sports that are played with some sort of board as the primary equipment. These sports take place on a variety of terrains, from paved flat-ground and snow-covered hills to water and air. Most boardsports are considered action sports or extreme sports, and thus often appeal to youth. Some board sports were marginalized in the past. However, many board sports are gaining mainstream recognition, and with this recognition, they have enjoyed wider broadcast, sponsorship and inclusion in institutional sporting events, including the Olympic Games.
Inline skates are a type of roller skate used for inline skating. Unlike typical roller skates, which have two front and two rear wheels, inline skates typically have two to five wheels arranged in a single line. Some, especially those for recreation, have a rubber "stop" or "brake" block attached to the rear of one or occasionally both of the skates so that the skater can slow down or stop by leaning back on the foot with the brake skate.
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimised for topography, application and a frame with a suspension mechanism for the rear wheel. Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper posts can be installed to allow the rider to quickly adjust the seat height.
Grass skiing, skiing on grass, is a training method for alpine skiing and an established sport of its own. The skis used for grass skiing are short with rolling treads or wheels. These skis are attached to the skiers' boots. Depending on the skill of the grass skier, high speeds and jumps can be navigated.
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 a variation of skateboarding typified by the use of longer boards ("decks") with longer wheelbases and softer wheels. While longboards vary widely in shape and size, compared to street skateboards longboards are designed to be more stable at speed and to have more traction due to larger wheel sizes and softer wheel durometers. While standard street skateboards may typically be between 28 to 34 inches long, longboards can range anywhere from 32 to 50 inches in length. Ride characteristics of longboards generally differ from that of street skateboards due to the use of specialized longboard trucks that have different properties than those typically used with skateboards; while street skateboards use "traditional kingpin" (TKP) trucks that are optimized for tight turning radii, ollie and flip tricks, slides, grinds, and transition skating, longboards are typically paired with "reverse kingpin" (RKP) trucks that are designed for increased stability at higher speeds, more "surfy" carving characteristics, and/or greater ride comfort for commuting over longer distances.
The Tweel is an airless tire design developed by the French tire company Michelin. Its significant advantage over pneumatic tires is that the Tweel does not use a bladder full of compressed air, and therefore cannot burst, leak pressure, or become flat. Instead, the Tweel's hub is connected to the rim via flexible polyurethane spokes which fulfil the shock-absorbing role provided by the compressed air in a traditional tire.
A centreless wheel is a wheel that lacks a centre or hub, instead being supported and driven at the rim.
A skateboard is a type of sports equipment used for skateboarding. It is usually made of a specially designed 7–8-ply maple plywood deck and has polyurethane wheels attached to the underside by a pair of skateboarding trucks.
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 and are influenced by a number of factors including sociocultural evolution, mass media, music, technology, corporate influence and individual skill level.
A freeboard is a specialist skateboard designed to closely simulate the behavior of a snowboard. Freeboards were developed to allow snowboarders to transition to skateboarding without the need to adapt to a smaller deck and narrower wheel-base.
A brakeboard is a skateboard fitted with a specialised truck assembly that includes a braking mechanism.
Rayne Longboards is a Canadian longboard manufacturer. Rayne Longboards are shipped to retail shops in many countries, and they are also sold through their online store. The specialized boards are made for downhill racing, freeriding, city riding, and long distance pushing.
An electric skateboard is a personal transporter based on a skateboard. The speed is usually controlled by a wireless hand-held throttle remote, or rider body weight-shifting between front of the board for forward motion and rear for braking. As for the direction of travel to the right or left, it is adjusted by tilting the board to one side or the other. The classification of electric skateboards and legality of their use on roads or pavements varies between countries.
A Penny board is a type of skateboard that is characterized by a short and narrow plastic deck. Although such skateboards were first manufactured during the 1970s, their name, and contemporary popularity come from the Australian brand Penny Skateboards, founded in 2010. The company's name has since been widely genericized to describe all small plastic skateboards.
Roominate is a construction set introduced by Maykah Inc., a company founded by Alice Brooks and Bettina Chen, in 2012. The product, marketed at girls aged 6–10, consists of modular plastic building pieces that can interlock to create models and includes circuits that can be wired. Originally funded through Kickstarter, the company received an investment from Mark Cuban and Lori Greiner during the sixth season of Shark Tank. In 2016, Roominate was acquired by toy manufacturer PlayMonster.
Syntorial is a synthesizer-teaching software created by Audible Genius, a company owned by website programmer, musician and teacher Joe Hanley. He was inspired to make the program by his frustration of learning synthesis in his early career, and wanted to create something that would train the user to design a patch by ear. Kickstarter-funded in 2012, the program was officially released for Microsoft Windows and OS X on August 27, 2013, and for the iPad on June 25, 2015. The synth that is built into the software is called Primer, which was released as a VST and AU in November 2013. Syntorial garnered critical acclaim with reviewers praising it a fun way to learn synthesis, earning an Editors’ Choice Award from Electronic Musician in 2014. The latest version of Syntorial is 2.0, which was released in July, 2023.
Boosted was an American manufacturer of electric skateboards and electric scooters based in Mountain View, California.
