Abstract
A rotatable folding bicycle stem includes a stem rotatably mounted on the standpipe with defining a stem rotating axis. An upper end of the stem terminates in a forwardly projecting O-shaped loop. A distance between the stem rotating axis to a center of the O-shaped loop is smaller than a distance between the standpipe rotating axis to the center of the O-shaped loop. A space between the handlebar and the frame could be reduced or became smaller by utilizing the present invention. The smaller folded size of the folding bicycle facilitates storage by users and is beneficial in that the bicycle may be stacked or compacted more tightly when loading in a cargo car of a container for delivery, thereby reducing a shipping cost for a single bike and increasing a loading quantity in single container.
