A cargo support device increases the cargo-carrying capacity of standard two-wheeled vehicles, such as bicycles, motorcycles, and mopeds. The cargo support device includes a base extension frame mounted to the two-wheeled vehicle. The base extension frame can be mounted to the bottom bracket shell or detachably mounted at three connection points to the bottom bracket shell or chainstays and rear wheel dropouts of the two-wheeled vehicle. The rear wheel assembly is transferred from its original dropouts to new dropouts located on the base extension frame. The original chain, rear brakes, and gear accessories, if any, are extended so as to accommodate the displacement of the rear wheel assembly of the two-wheeled vehicle. The cargo support device further includes a cargo storage device, such as a support frame with or without fold-down racks and at least one bag, vessel, container, lockable bin, or box-type attachment, or a long-load carrier, or a child seat, or a heavy-duty box-type compartment, which can be attached to the base extension frame. |
