A rotatable folding bicycle stem comprises a stem (20) rotatably mounted on the standpipe with defining a stem rotating axis (B). An upper end of the stem (20) terminates in a forwardly projecting O-shaped loop (23). A distance between the stem rotating axis (B) to a center of the O-shaped loop (23) is smaller than a distance between the standpipe rotating axis (A) to the center of the O-shaped loop (23). Compared with the conventional folding bicycle, a space between a handlebar and a frame (D) could be reduced or became smaller by utilizing the present invention. The present invention is able to provide a smaller folded size of the folding bicycle for facilitating storage by users and benefiting for being stacked or compacted more tightly when loading in a cargo car of a container for delivery. The present invention could reduce a shipping cost for a single bike and increase a loading quantity in single container.
