Abstract: A carrier rack for easy attachment to and removal from a standard bicycle seat. The carrier includes a support which in use extends over the rear wheel of the bicycle. A seat post abutment fork located at the front end of the support is configured to at least partially encircle and abut the seat post just under the enlarged portion of the seat post. A rail hanger is attached to the support and extends upward from the support at a location forward of the center of gravity of the support. In a preferred embodiment arms of the rail hanger extend over the saddle rails of a standard bicycle seat at a pivot position near the knees of the rails so as to support the weight of the rack and its burden in a hanging fashion with the seat post abutment fork partially encircling the seat post.
