ABSTRACT:
A resilient bicycle having a front wheel, a rear wheel, and a frame structure, including a head tube with a down strut. A level extension stem is provided at an end of the down strut and a tread board is fixed on top of the level extension stem for being treadled by a user standing on it. A rear fork member with an inclined connection plate at each end is connected to the rearward end of the extension stem. A hub fitting is eccentrically arranged in the rear wheel through a plurality of different length spokes and a transmission mechanism is elastically connected between the hub fitting and the rear fork member for converting the vibrating motion created by treadling into a rotational motion for driving the rear wheel. By repeatedly causing the tread board to be pushed down and rebound, the bicycle smoothly moves forward.
