<p>A foldable bicycle capable of being pulled and pushed has a frame (10) on which a foldable structure (40) is arranged. The foldable structure (40) divides the frame (10) into a fixed section (12) and a foldable section (11) and enables the foldable section (11) to be folded toward to the fixed section (12) between an extended position and a folded position. The fixed section (12) includes a seatpost (121) and a five way union (122). An auxiliary wheelset (20) is arranged under the five way union (122) to pull and push the bicycle after it is folded. Two cranks (30) are separately pivoted at either sides of the five way union (122). Each crank (30) can rotate along a circular trace. In the folded position, the foldable section (11) is not located at the moving trace path of the cranks (30). Therefore, after being folded, the foldable section (11) does not impact on the rotating crank (30), thus enabling a forward push and backward pull of the bicycle.</p> |
