Abstract: A bicycle protective cover comprised of a fabric or plastic flexible material that conveniently and easily wraps around and completely encloses a bicycle. The cover is provided in a single piece having pockets contoured to comfortably fit the bicycle seat and the handlebars. Each of these pockets is closed by a hook and loop fastener. Circular portions at each end of the cover are provided with flexible elastic borders allowing them to be stretched around and retained on the front and rear wheels. The remaining panel of the cover then folds over the bicycle to completely seal and enclose the bicycle. The closing panel is provided with an elastic cord around the periphery of its border to draw the cover tight once it is completely wrapped around the bicycle. The cover includes webbing appropriately placed to aid in conveniently aligning the cover with the wheels, the seat, or the handlebars.
