It is of such a size that an adult can ride it without inconvenience, and is equipped with a bicycle handlebar folding apparatus (10) for convenience when parking in small spaces and when transporting. The bicycle of the present invention is also equipped with pedal crank arm detachment apparatus (20) which reduces the volume occupied by the bicycle to less than the width of the saddle, a detached drive shaft apparatus (30) which reduces the length of the bicycle and facilitate carrying and transporting, and an apparatus which adjusts length of frame (40). The portable bicycle of the present invention is a very useful invention that provides a method of decreasing or increasing the length and volume of the bicycle in order to facilitate carrying, storing and transporting in public transport such as buses and subway trains, by minimising the size of the bicycle. |
