— Recently there are studies on air pollution of big cities and results proved that air pollution is increased in general. This problem is the base of our research and so we should try to decrease this. Regarding to the point that some people for solving this problem use bicycles as a transportation .We decided to design a bicycle that is self - propelling. Also it can be folded when is needed. In this way it can be placed in a small bag .Another important point about it: Doesn’t need for any external electrical supply and fossil fuel. General system of this bicycle is in saving energy in batteries with pedal and then used as energy for moving bicycle automatically.
— Bicycle, air pollution, electrical energy, propel, fold.
