A foldable bicycle includes a main frame, a front frame, a swingable middle frame, and a rear strut. The main frame includes a front casing, a middle pivoting member, and a rear pivoting member. The front frame is inserted into the front casing. The swingable middle frame includes an upper section, a middle section pivotally connected with the middle pivoting member, and a lower section including a guiding groove. The guiding groove includes first and second groove ends. The distance between the first groove end and the middle pivoting member is greater than that between the second groove end and the middle pivoting member. The rear strut includes a first end pivotally connected to the rear pivoting member and a second end connected to a slider. The slider is slidably received in the guiding groove and capable of being selectively moved between the first and second groove ends. |
