The support is connected with a fly wheel axle, a primary chain shaft and a rear seat support in a bent manner; and the front portion of the support is a horizontal T-shaped body, front heads of pedals penetrate into two lateral grooves of the T-shaped body, and springs are arranged at the groove bottoms to guarantee that no swinging is generated in up-down movement of the pedals and the pedals will rebound when reaching the bottoms. The pedals can drive lifting handles, a primary chain wheel and a chain to drive a fly wheel and double rear wheels to land; and the left pedal, the right pedal, the lifting handles, the primary chain wheel, the fly wheel and a brake can be hidden in the intermediate distance. The front ends of the pedals are wide and large, so that the user can feel comfortable when putting feet at the front ends of the pedals in sitting and when standing up to step the pedals.
