ABSTRACT:
A foldable bicycle carriage including a base frame, a support frame, two upper folders, two lower folders, a drag link, a wheel shaft, two wheels, a base board and a cover. Each of the upper and lower folders includes a frame seat for securing the upper and lower folders respectively under a rear edge of the support frame and on a rear edge of the base frame. The upper and lower folders can be inward folded to reduce the volume of the entire frame body of the carriage so as to facilitate the storage and transferring thereof. An insertion pin seat is disposed at the front end of the drag link and is directly tightened by a manually operable plum blossom-shaped thread sleeve. The insertion pin seat is further located by a safety pin. The bicycle carriage can be easily assembled and conveniently used.
