Freestyle tricks involve balancing on some other part of the board than all four wheels, such as two wheels or one wheel, the tail of the board, or the edges on either side. Various ways to flip and manipulate the board in and out of these stances were invented in the earliest years of skateboarding and these form the basis of freestyle or flatground skateboarding.
