To put it bluntly, it means rushing downhill. The speed is very fast. Generally, the speed on steeper and longer slopes can reach 6.70 mph. The world's fastest record is 130 kilometers per hour. However, in China, there are still very few places for downhill riding.

From the functional classification of skateboards, they can generally be divided into two major categories: road boards (in a broad sense) and rocker boards.

The double-saw board is probably the most common and popular one nowadays. It is characterized by a wooden board with both ends tilted up. Also called street skateboarding, it is mainly used to play with various moves and props. The most basic but not simple move is ollie, which is jumping with a board. This is why some people say that the soles of skateboarding feet are like glue.

Road boards are also divided into: long boards (road boards in a narrow sense), big fish boards, small fish boards, banana boards, etc. Longboards are mainly used for downhill riding and rarely do street skateboarding movements, and their prices are also on the high side. Some people also like to use long boards to paint the streets. . Of course, the ones used professionally for street painting are the big fish board and the small fish board and banana board. There is no essential difference between these types, the only difference is the shape and size of the boards. The difference between them and longboards is not only functional, but also that they have plastic boards and single-warped boards. The wheels are the same as those used on longboards. Compared with double-turned wheels, roadboard wheels are generally larger and softer to adapt to more complex road conditions.
