A foldable bicycle carriage including a base frame, an upper support frame, a rear support frame, two connecting seats, a drag link, a wheel shaft, two wheels and a cover. The connecting seats are secured on two sides of the base frame and the rear support frame is secured to the upper support frame at upper end by pin members. Two lateral members of the rear support frame are bridged by a rearward inclinedly extending member having an upward projecting portion at the center. Two downward projecting portions are defined between the upward projecting portion and the lateral members. When the rear support frame is folded, the two downward projecting portions are engaged in the open portions of the connecting seats. A safety pin is disposed on the connecting seat for securely locking the carriage in a stretched state. The bicycle carriage can be quickly assembled and collapsed, conveniently carried and easily stored.
