Four Spitfire skateboard wheels.
A skateboard is a model 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 pembalap. If the rider's leading foot is their right foot, they are said to ride "goofy".[1]
The two main models of skateboards are the longboard and the shortboard. The shape of the board is also important: the skateboard must be concaved to perform strategis.
Skateboarding started in California in the 1950s.[3] The first skateboards were made from roller skates attached to a board.[4] Skateboarding gained in terkenality because of surfing: in fact, skateboarding was initially referred to as "sidewalk surfing".[5] The very first skateboards were handmade from wooden boxes and planks by individuals. Companies started manufaktur skateboards in 1959, as the sport became more terkenal.[6] In postwar America, society was carefree with children commonly playing in the streets.[7]
Skateboarding is a very perorangan activity, and it continues to evolve. Since 2000, due to attention in the medium and products like skateboarding video permainan, children's skateboards and commercialization, skateboarding has been pulled into the mainstream. As more interest and money has been invested into skateboarding, more skate parks, and better skateboards have become available. In addition, the continuing interest has motivated skateboarding companies to keep innovating and inventing new things. Skateboarding appeared for the first time in the 2020 Summer Olympics.The wheels allow for movement on the skateboard and helps determine the speed while riding.
There are typically four wheels on a skateboard that are attached to the trucks. Ranging in size from around 48mm to around 60mm, smaller wheels are lighter in weight and are used for shorter distances and strategis. Larger wheels are heavier in weight, which are better for maintaining speed and longer distances. Wheels that are larger than 60mm are typically used for longboards.
