The invention provides a long-lever pedal bicycle transmission mechanism. A traditional bicycle is taken as a reference; a middle shaft of a traditional bicycle penetrates through a hollow shaft of a rear wheel, traditional chain transmission is changed into gear transmission, and two long-lever pedals are installed in the length distance space on the two sides of a bicycle body. A crank-link mechanism is utilized; and the wheels are driven to rotate through gear transmission in the crank wheel. Meanwhile, the up-and-down treading amplitude of the pedals which are the same as those of a traditional bicycle is guaranteed through a swing rod and a sliding block mechanism. The transmission ratio of the gears is correspondingly increased under the lever labor-saving condition, so that the running speed of the bicycle is increased. And if carved by a modern manufacturing process, the product can be quickly accepted by the public.

    本发明提供一种长杠杆脚踏板自行车传动机构。以传统自行车为参照;是将传统自行车的中轴从后轮空心轴内穿过,将传统链传动改为齿轮传动,在车身两侧的长度距离空间,安装两个长杠杆脚踏板。利用曲柄连杆机构;通过曲柄轮内的齿轮传动驱动车轮旋转。同时利用摆杆与滑块机构,来保证与传统自行车相同脚踏板的上下踩踏幅度。在杠杆省力地情况下相应增大齿轮的传动比,来提高自行车行驶速度。如果在现代制造工艺雕琢下,很快会被大众所接受。
