one. The origins of skateboarding: At the end of the fifties of the fifteenth century, the descendants of Edison, who were good at inventing and invented, turned the fantasy of the ancient Divine people into reality more or less. In the early fifties the west coast of the United States was a place where the people of the tide had a big try. They use ordinary wood and expensive balsa wood surfboards to find fun on the cusp. By the mid-1950s, molded polyurethane foam and fiberglass replaced the wooden surfboard. The mobility and durability of these new surfboards make surfing popular in the late 1950s. Skateboarding is an extension of surfing on land. The former is limited by geography and climate, while the latter has greater freedom.
In the late fifties, the residents of the Southern California beach community invented the world's first skateboard, a 50X10X50CM wood plate fixed on the roller skating iron wheels. However, such a simple exercise equipment, but because it can bring people and surf the same feelings, began to attract attention. The second generation skateboard was born in 1962, made of oak plywood, roller skating bridge and plastic wheels. Compared with the first generation skateboard, this skateboard is undoubtedly a leap in technology. However, the performance of this slider's plastic wheel is still unsatisfactory. It is too small to attach the friction to the skateboard when out of control; and its low elasticity makes the skateboard encounter even a small obstacle will come to an end, the skater fell off. At the same time, its wear resistance is also poor. Nevertheless, this skateboard is still popular with skaters. After all, compared with the previous generation skateboard, it has been a great degree of evolution, relatively large board so that skaters are easier to stand and manipulate.
In 1973, a skateboarder named Frank made his polyurethane wheel on his skateboard for the first time and achieved an unexpected effect. This flexible wheel is not only wear-resistant, and can make the skateboard safe and securely sharp turn, easy to run over the ground on the small obstacles. This is the third generation skateboard. The mid-seventies, is the rapid development of skateboard period, the potential of polyurethane is greatly played out. A variety of materials pedal, steering bridge has mushroomed. And the United States throughout the dotted skateboarding company also reveals to people a new movement of the arrival. As the skateboard is the derivative of the surfing movement, the seventies skateboarding culture with surfing marks, skateboarders built skateboarding parks are in the simulation surfing terrain. Until the United States California Santa Monique's "westerly" skateboard team to abandon the surf props, the first time the keyhole pool as a practice vertical surface skateboarding the venue, and set off in the United States "pool skateboarding", thus, skateboarding began to surf , Not only from the equipment, venues, but also from the staff completely separated, and formed their own language, skills, dress style and music hobbies. At the end of the eighties, due to the development of skateboarding itself and the improvement of skateboarding requirements for skateboarding and the need for two-way gliding in order to accommodate the two-way gliding of the first three generations of skateboards , The shape of the symmetrical skateboard appeared, this is the fourth generation skateboard. The material used to make this skateboard is called hard rock, lighter, and elastic. Skateboard wheel high hardness, good elasticity, more suitable for high-speed taxi. Due to the weight balance, the fourth generation skateboard is more suitable for all kinds of flip action.
