Abstract
A stepping scooter includes a scooter body for supporting a rider, a moving system, a driving system and a steering lever. The moving system includes a driving wheel rotatably connected with the scooter body, a driven wheel coaxially aligned with the driving wheel and rotatably connected with the scooter body. The driving system includes a driving arrangement pivotally connected to the scooter body, and a transmission and speeding up arrangement engaged with the driving arrangement to convert a human power applied on the driving arrangement into a rotation power to drive the moving system. When the human power is applied on the driving arrangement, the driving wheel is rotated so as to drive the driven wheel to move forward. On the other hand, the transmission and speeding up arrangement is capable of increasing a transmission velocity twice to save a physical force for the rider at the same time.
