The invention relates to a multi-speed-change tool and a mechanical bicycle and is mostly used in the field of transportation. The multi-speed change tool mainly comprises a driving shaft, a driving wheel, a plurality of speed change wheels and a plurality of speed change shafts, a mechanical bicycle mainly comprises multiple speed change tools, a low-speed device, a bicycle body and wheels of a bicycle or an electric bicycle or a motorcycle in the prior art. When the mechanical bicycle pedals forwards, the speed of the mechanical bicycle reaches or even exceeds the speed of the electric bicycle or motorcycle in the prior art through multiple speed change tools, and when the mechanical bicycle pedals backwards, the speed of the mechanical bicycle moves forwards slowly through a low-speed device. The multi-speed change tool is advantaged in that the bottleneck that the bicycle in the prior art can move forwards only by pedaling forwards is broken through, and a series of problems that oil for the motorcycle in the prior art is not environmentally friendly, resources are consumed, charging of the electric bicycle is not safe, a battery is prone to explosion, the battery is not takeninto a room to be charged in a residential area, and charging of the electric bicycle is troublesome are solved. The mechanical bicycle has advantages of quickness, labor saving, no resource consumption and environmental protection, and is an ideal vehicle for people to go out.

    本发明涉及一种多道变速用具及机械单车,多用于交通运输领域。多道变速用具主要包括驱动轴,驱动轮,多个变速轮,多条变速轴组成。机械单车主要包括多道变速用具,低速装置,现有自行车或电单车或摩托车的车体及车轮组成。机械单车具有往前蹬脚踏板时,通过多道变速用具达到甚至超过现有的电单车摩托车速度,也具有往后蹬脚踏板时,通过低速装置慢速前行的速度。打破了现有自行车只能往前蹬才可以前行的瓶颈,也解决了现有的摩托车用油不环保,消耗资源,电单车充电不安全,电池易爆炸,住宅区不让带电池入室内充电,使电单车充电麻烦的一系列问题。本机械单车具有快速省力,不消耗资源环保的优点,是人们出行理想的交通工具。
