The invention relates to an electrically-assisted four-wheel bicycle. The bicycle is mainly composed of a bicycle frame, a front axle, a rear axle, a seat, wheels, brake pads, brake discs and a gear speed change device. A clutch handle is arranged on the electrically-assisted four-wheel bicycle to be matched with a clutch for use, so that the electrically-assisted four-wheel bicycle can be started on an uphill road and can also be started during long-distance driving. A storage battery pack drives a motor to charge through friction force generated during braking and can also be charged through an external charging facility. A steering gear and a steering rack of the front axle rotate in a matched mode, so that steering is smoother and operation is easy, a compartment shell is additionally arranged, the safety performance is greatly improved when people ride the bicycle, and people do not need to worry about the influence of atrocious weather. A lengthened foot rest lever is adopted, under the condition that a rider uses the same strength, the output power of pedals is greatly improved, the rider can ride the bicycle more conveniently and more comfortably for a longer distance, and a novel environment-friendly sports-exercise-type traffic tool is developed.

    本发明涉及一种电助力四轮自行车,主要由车架、前轴、后轴、座椅、车轮、刹车片、刹车盘、齿轮变速装置组成。本电助力四轮自行车上设有离合器手柄配合离合器的使用,可以在上坡路时启动,也可以在长途行驶时启动。蓄电池组通过刹车时产生的摩檫力带动电机充电,也可以借助外部充电设施充电。前轴的转向齿轮、转向齿条配合转动,使得转向更顺畅和易于操作,增加了车厢外壳,使人们骑行时安全性能大幅度的提高,也无需担忧恶劣气候的影响。本发明采用了加长的脚踏杆,在骑行者使用同等力量的情况下,将很大程度提升脚踏板的输出功率,会使人骑行更轻便,更舒适,更远途,开辟了一种环境友好的新式运动键身型交通工具。
