Abstract

The invention relates to a folding device of a compact-type vertical sports bicycle. The folding device has frames at the left side and the right side, a steering fixing plate and a centre shaft. The folding device is characterized in that: the folding device takes a centre shaft connected with the frames and the steering fixing plate as a rotation centre, and the centre shaft is provided with a pair of slider-crank mechanisms in inverse symmetry for keeping relative position relation between the frames and the steering fixing plate, thus realizing skillful combination between a folding mechanism and the entire bicycle, and then developing the bicycle with extremely small and compact structure and extremely convenient folding. The bicycle has about 1 / 3 of the weight and about 1 / 4 of the size of the conventional bicycle and the same speed as the conventional bicycle. Two feet stand on the left pedal and the right pedal when the bicycle is in use, which conforms to exercise habit of human body and allows a person to realize exercise by alternately pedaling, thus allowing the person to actually enjoy fun of pedaling exercise.
