A pack assembly includes a plurality of frame sections each having side braces connected by pivotal joints and provided with a shiftable pack mount including slidable locking sleeves. With the pack mount in a first position juxtaposed an intermediate one of the frame sections, the sleeves overlie the pivotal joints to retain the pack assembly in an extended back pack mode and when the pack mount is axially displaced along the side braces to an adjacent frame section uncovering the pivotal joints, the frame sections are angularly displaceable about the pivotal joints to provide a pack assembly of inverted U-shaped configuration adaptable for transporting astride a vehicle wheel.

A convertible pack assembly including, a frame assembly including upper, medial and lower frame sections, each said frame section having a pair of laterally spaced apart side braces, transverse pivot joints connecting said frame sections in series, said frame sections displaceable about said pivot joints into a first mode with said frame sections substantially longitudinally aligned, a slidable pack mount provided with a plurality of lockable sleeves overlying said pivot joints when said pack mount is juxtaposed said medial frame section to fixedly retain said pack assembly in the said first mode, said pack mount including top and bottom cross members connecting laterally adjacent pairs of said lockable sleeves, a vertical rod extending from said top cross member and disposed through said bottom cross member, said pack mount and sleeves axially shiftable from juxtaposition said medial frame section to a point juxtaposition said lower frame section with said pack mount being collapsed when shifted to said lower frame section as the axial distance is reduced between said top cross member and its connected sleeves and said bottom cross member and its connected sleeves whereby, said pivot joints are uncovered and said plurality of frame sections are displaceable about said joints to a folded second mode.
