A bicycle storage frame for storing fluids includes a hollow fluid-tight frame section having a wall structure and an internal fluid chamber and at least one liquid fill opening formed in the wall structure accessing the internal fluid chamber of the frame section. At least one gas fill valve extends through the wall structure to access the internal fluid chamber for inputting of pressurized gas into the frame section and at least one liquid release valve extends through the wall structure accessing the internal fluid chamber for release of liquid held within the frame section. At least one gas release valve extends through the wall structure accessing the internal fluid chamber for releasing pressurized gas from within the frame structure and a gas transfer device such as an air chuck is connected to the gas release valve externally of the frame section for transferring gas from within the internal fluid chamber to a tire for inflation thereof.

A superefficient bicycle frame having a plurality of dual tapered rectangular or square cross section frame members having constant wall thickness. The torsional/bending section modulus of a member is changed by providing a dual taper to the cross section of the frame members so that larger cross sections are used at points of greatest stress and smaller cross sections are used at points of lower stress. The method of manufacture is to cut various two dimensional shapes from sheet stock which are bent along nonparallel bend lines to form the various members. This method of manufacture permits the ends of the section members to be shaped as desired by laser or plasma cutting, or other means, in the flat before bending. The tapered frame members are then connected to form a superefficient frame.
