Abstract
A foldable bicycle is provided, which comprises a frame, a front wheel, a vertical bar, a rear wheel, and a saddle. The frame is composed of a front frame and a back frame, and the back frame is provided with a chamber. The back end of the front framework and the front end of the back wheel are connected with each other through a central shaft. The back frame is provided with a power shaft, which is connected with a brace and a pedal. The power shaft is connected with the rear wheel shaft through a gear cluster. The front fork is positioned on the vertical bar, which is connected with the front end of the front frame through two chain panel turnover mechanisms. The saddle is positioned on a supporting bar, which is connected with the back frame with the power shaft's spindle as the pin. The supporting bar is a two-section expansible structure. When the utility model is folded, the front frame rotates along the central shaft to draw in the chamber of the back frame. The vertical bar and front fork rotates an angle of 180 degree, with the front wheel in parallel with the rear wheel. The folded utility model does not have any protruding spare parts, thus being applicable to vertically be positioned in public traffic tools; the product can also be moved through the rolling of the front and rear wheels, so it is convenient to move it.
