In addition, the structure provided for connecting the lower ends of the upstanding side portions of the protective frame to the opposite side rearwardly projecting portions of the bicycle frame between which the rear bicycle wheel is conventionally journaled includes a generally horizontally disposed and rearwardly opening semi-cylindrical portion which projects forwardly of the lower end portions of the upstanding opposite side portions of the protective frame and has its central portion provided with structure for anchoring to the upper rear portion of the bicycle frame from which the bicycle seat is conventionally supported.
