The invention provides a conveniently folded bicycle. The conveniently folded bicycle comprises a frame, a front fork and a rear fork, wherein the frame comprise a frame transverse tube, a vertical tube and a front fork tube, the frame transverse tube consists of a front frame transverse tube and a rear frame transverse tube, and the front frame transverse tube is pivotally connected with a fronthinged plate on the front fork tube; a rear hinged plate on the rear frame transverse tube is pivotally connected with a vertical tube hinged plate of the vertical tube by a hinged shaft; the rear fork is pivotally connected with the hinged shaft, and the rear fork is fixedly connected with the vertical tube or is pivotally connected with the rear frame transverse tube; the front and the rear frame transverse tubes are pivotally connected by a fixed shaft, the lower ends of the front and the rear frame transverse tubes are pivotally connected with the fixed shaft, and the upper ends of the front and the rear frame transverse tubes are fixedly connected by a hand shaft; the front end of a front connecting rod is pivotally connected with the front hinged plate, and the rear end of the frontconnecting rod is pivotally connected with the hand shaft; and the front end of a rear connecting rod is pivotally connected with the hand shaft, and the rear end of the rear connecting rod is pivotally connected with the vertical tube. When the bicycle needs to be folded, a pin is separated from a fastener and the front frame transverse tube, the hand shaft is lifted upward by hands, and then the bicycle is folded; and when the bicycle needs to be unfolded, the front fork tube and the vertical tube are held by hands and pulled toward both sides, the fastener is overlapped with the front frame transverse tube, and then the pin is used for fixing. Therefore, the bicycle can be conveniently folded and unfolded.
