A riding luggage storage system includes two side boxes symmetrically arranged, a side box pull rod movably arranged on each of the side boxes, a rolling structure installed on the outer lateral side of each side box, and two side boxes quickly mountable to form a draw-bar box. The luggage storage system has a compact and reasonable integral structure, and has at least one side boxes, with movably installed pull rods. A box body can be carried directly and artificially and moved between different places directly. The box body is easy to carry and suitable for carrying by riding vehicles such as motorcycles and bicycles.
