Skateboard

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 can also be used by standing on the deck while on a downward slope and allowing gravity to propel the board and the rider.

[2] Skateboarding, as it exists today, was probably born sometime in the late 1940s, or early 1950s,[3][4] when surfers in California wanted something to do when the waves were flat.

In addition, the continuing interest has motivated skateboarding companies to keep innovating and inventing new things.

[10] The longboard, a common variant of the skateboard, is used for higher speed and rough surface boarding, and they are much more expensive.

[11] The wheels allow for movement on the skateboard and helps determine the speed while riding.

Ranging in size from around 48mm to around 60mm, smaller wheels are lighter in weight and are used for shorter distances and tricks.

The hanger and baseplate are joined by a kingpin, allowing the truck to swivel and turn.

[16] Trucks for skateboards come in a variety of forms and sizes and can be modified to the rider's preferences.

[20] Deck rails are thin, plastic strips usually screwed into the bottom section of a skateboard to decrease friction while performing slide tricks and protecting the board’s graphic from damage.
