Abstract:
1. A structure for laterally moving a folded folding bicycle including a top tube, a seat stay, a front wheel, a rear wheel, a crank arm, a seat, and a seat tube, comprising: a front assembly for wheeling laterally comprising a first auxiliary wheel, the front assembly for wheeling laterally being slidably secured to a lower portion of the seat tube; and a rear assembly for wheeling laterally comprising a sleeve secured to the seat stay, the sleeve comprising a longitudinal substantially J-shaped opening having an upward directed notch at a lower end, a support tube having a stop at the top, a second auxiliary wheel rotatably secured to the bottom of the support tube, an elastic member, and a threaded lever, wherein the support tube is inserted through the sleeve and the elastic member to secure to the stop and the lever is driven through an upper end of the opening into the support tube to slidably secure the support tube to the sleeve with the elastic member being biased between the stop and the sleeve; and wherein in response to folding the folding bicycle the lever is adapted to push downward to slide along the opening until entering the notch to be locked therein so as to further bias the elastic member, change an orientation of the second auxiliary wheel from being parallel to that of the rear wheel to be perpendicular to that of the rear wheel, and cause the second auxiliary wheel to contact the ground.
