The invention discloses a power-assisted bicycle which consists of a frame, a lever, a driving device, a chain, a driving shaft and front and rear wheels. According to the bicycle, long levers are used as pedal feet for amplifying gravity, energy is stored through springs on the levers, the bicycle is driven through an output shaft and a labor-saving pulley principle, the structure is simple, energy can be output after being stored, and more labor is saved for bicycle riding.

    一种助力脚踏车,由车架、杠杆、驱动装置、链条、驱动轴及前后轮组成,该脚踏车利用长杠杆做踏脚,将重力放大,通过杠杆上紧弹簧来储蓄能量,再通过输出轴和省力滑轮原理来驱动脚踏车,不仅结构简单,而且可储蓄后输出能量,使踏蹬起来更省力。
