A bicycle capable of being folded twice for storage and carrying comprises a frame body, a chain driving unit, a control unit, and a cushion unit. One end of the frame body is formed with a pivotal hole for being engaged with a locking screw and an opening hole for being engaged with a quick-detaching screw. Thereby, the lock frame body and the telescopic rod are connected by the two screws so that the frame body is foldable with respect to the telescopic rod. The similar structures are used to lock the frame body and the cushion unit so that the frame body is foldable with respect to the cushion unit. As a result, a bicycle capable of being folded twice for storage and carrying can be realized by above-mentioned structure.
