A scooter includes one or more wheels attached to the rear portion of a board, and a shaft rotatably secured to the front portion of the board for supporting one or more front wheels. A cushioning device is disposed between the board and the shaft for preventing the board from striking onto the shaft and for allowing the riders to more comfortably ride the scooter. One or more poles are secured between the board and the shaft, and one or more springs are engaged between the board and the shaft for cushioning the board.
