Skateboards
A skateboard is a type of sports equipment used for skateboarding. They are usually made of a specially designed 7-8 ply maple plywood deck and polyurethane wheels attached to the underside by a pair of skateboarding trucks. The skateboarder moves by pushing with one foot while the other foot remains balanced on the board, or by pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by simply standing on the deck while on a downward slope and allowing gravity to propel the board and rider. If the rider's leading foot is their right foot, they are said to ride "goofy". The two main types of skateboards are the longboard and the shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks. History Skateboarding started in California in the 1950s. The first skateboards were made from roller skates attached to a board. Skateboarding gained in popularity because of surfing: in fact, skateboarding w ...

Skateboarder In The Air
Skateboarding is an action sport originating in the United States 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. 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. Since the 1970s, skateparks have been constructed specifically for use by skateboarders, freestyle BMXers, aggressive skaters, and more recently, scooters. However, skateboarding has become controversial in areas in which the activity, although illegal, has damaged curbs, stoneworks, steps, benches, plazas, and parks.

Penny Board
A Penny board is a type of skateboard that is characterised by a short and narrow plastic deck. Although such skateboards were first manufactured during the 1970s, their name and contemporary popularity comes from the Australian brand Penny Skateboards, founded in 2010. The company's name has since been widely genericised to describe all small plastic skateboards. History The first line of plastic skateboards was launched in the 1970s by Larry Stevenson for his Makaha brand. Grentec also began to manufacture plastic skateboards.Courtney RubinPenny Skateboards Find a Niche ''Nytimes.com'', 22 July 2015 These plastic skateboards were widely popular during the early 1970s, although the era's professional skaters still shunned them in favour of wooden boards. By 1978, laminated wooden decks had become the industry standard. Ben Mackay created the Penny board in 2010, from which the brand Penny Skateboards was born. McKay named the brand for his sister, Penny. The idea behind th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Skateboard
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 (e.g. whether they qualify as a 'vehicle') and legality of their use on roads or pavements varies between countries. History Early incarnations The MotoBoard, which was gasoline-powered, was released in the summer of 1975 but was banned in California in 1997 due to noise and pollution. Modern electric devices Louie Finkle of Seal Beach, California is often cited as an originator of the modern electric skateboard, offering his first wireless electric skateboard in 1997 and a patent filed in April 1999, however it was not until the 2004–2006 that electric motors and batteries were avai ...

Longboard (skateboard)
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''. Available in a wide variety of shapes, longboards are typically designed and optimized for ''cruising'' (covering distances at moderate speeds), commuting (as a practical means of personal transport), and ''downhill (racing)''. The act of riding on a longboard in general is known as longboarding, which can also include more specialized forms such as longboard ''dancing'', which involves stepping up and down a board and other movements and m ...

Skate Shop
320px, Ridin' High Skate Shop in Burlington, Vermont A skate shop or skateshop is a store that sells skateboards and skateboarding apparel. When financially possible, skate shops sponsor local riders and promote skateboarding locally through skate videos and demonstrations, referred to as "demos". History In 1962, the surf shop "Val-Surf" in Hollywood became the first skate shop when they carried the first self-produced skateboards. These boards, sold complete, featured a surfboard shape and roller skate trucks. Professional skateboarder Jeff Grosso referred to skate shops as " Jedi temples for skateboarding".

Caster Board
A caster board, vigorboard or waveboard is a two-wheeled, human-powered land vehicle. Other names are J-board and RipStik (sometimes written ripstick or rip stick), both of which are derived from commercial brands. A caster board has two narrow platforms known as "decks" that are joined by a torsion bar, which consists of a metal beam, usually coated by rubber, that houses a strong spring. One polyurethane wheel is mounted to each deck with a caster so that each wheel can steer independently, and each caster has a steering axis that is tilted about 30° back from the vertical. Movement The motion requires that the board be twisted back and forth so as to move either just the back foot or both the front and back feet side to side, essentially pushing the board forward at the outside of the movement, before the foot is brought back in the other direction. In principle, the act is similar to what is required to propel one who is riding inline skates forward, as opposed to how s ...

Self-balancing Scooter
A self-balancing scooter (also hoverboard, self-balancing board, segway or electric scooter board) is a self-balancing personal transporter consisting of two motorized wheels connected to a pair of articulated pads on which the rider places their feet. The rider controls the speed by leaning forward or backward, and direction of travel by twisting the pads. Invented in its current form in early 2013, the device is the subject of complex patent disputes. Volume manufacture started in China in 2014 and early units were prone to catching fire due to an overheating battery which resulted in product recalls in 2016, including over 500,000 units sold in the United States by eight manufacturers. History Shane Chen, an American businessman and founder of Inventist filed a patent for a device of this type in February 2013 and launched a Kickstarter fund-raising campaign in May 2013. The devices' increasing popularity in Western countries has been attributed, initially, to endorsement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steering
Steering is a system of components, linkages, and other parts that allows a driver to control the direction of the vehicle. Introduction The most conventional steering arrangement allows a driver to turn the front wheels of a vehicle using a hand–operated steering wheel positioned in front of the driver. The steering wheel is attached to a steering column, which is linked to rods, pivots and gears that allow the driver to change the direction of the front wheels. Other arrangements are sometimes found on different types of vehicles; for example, a tiller or rear-wheel steering. Tracked vehicle Continuous track is a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle ...s such as bulldozers and tanks usually employ differential steering, where the tracks are made to move at different speeds or even ...

Hoverboard
A hoverboard (or hover board) is a levitating board used for personal transportation, first described in science-fiction, and made famous by the appearance of a skateboard-like hoverboard in the film '' Back to the Future Part II''. Many attempts have been made to invent a functioning hoverboard. In fiction Hoverboards were first described by author M. K. Joseph in a 1967 science fiction novel. In 1984, a hoverboard appeared in the shoot 'em up arcade video game ''SWAT'', developed by Coreland and distributed by Sega in Japan and Bally Midway in North America. The hoverboard was popularized by the '' Back to the Future'' film franchise, with its appearance in '' Back to the Future Part II'' (1989). During the 1990s there were rumors, fueled by the film's director Robert Zemeckis, that hoverboards were in fact real, but not marketed because they were deemed too dangerous by parents' groups. These rumors have been conclusively debunked. Hoverboards have appeared in various o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABEC Scale
The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). The ABEC scale is designed to provide bearing manufacturers dimensional specifications that meet the standards of precision bearings in a specified class. Manufacturers who produce equipment that require bearings must also know the dimensional tolerances to design parts that will accommodate a bearing. There are five classes from largest to smallest tolerances: 1, 3, 5, 7, 9. The higher ABEC classes provide better precision, efficiency, and the possibility of greater speed capabilities, but do not necessarily allow the components to spin faster. The ABEC rating does not specify many critical factors, such as load handling capabilities, ball precision, materials, material Rockwell hardness, degree of ball and raceway polishing, noise, vibration, and lubricant.
