Abstract
A skateboard includes a board body having a first section and a second section, at least a first wheel set connected to the first section, and at least two second wheel sets connected to the second section. The first wheel set includes a first base protruding from the first section. Each second wheel set includes a second base protruding from the second section and defines a reference line passing through a center of the second base. Both of the bases slope at an angle of 5 to 35 degrees respectively. An angle of not more than 60 degrees is formed between the reference line and a baseline passing axially through a center of the board body. The skateboard moves forward when the wheel sets are triggered by twisting a body of a user and a moving direction is changeable by shifting a center of gravity of the user.
