A scooter with one free-swaying rear-wheel set respectively located at rear end of the two fixed holding rods. The rear-wheel sets can sway freely to make the two rear wheels move leftward and rightward; hence, when operator's feet exert strength on said two fixed holding rods, the two rear wheels will be driven to move forward like S-shaped pathway. Moreover, through the coordination of the front wheel, stand rod and handle, the operator will be able to practice different car-driving actions of turning the body, hips and hands around, and different strength-exerting ways, such as by twisting one foot or two feet synchronously. Therefore, the operation of a scooter has the effect of being simple, having the feature of both fun and recreation.
