This is a full-sized folding bike (standard 26" wheels) and a fully capable mountain bike that features the same patented Folding Integrated Technology (F.I.T.) in the Paratrooper Military Mountain Bike that Montague developed for the U.S. Marines to deploy from aircraft. The F.I.T. design allows the bike to fold via concentric seat tubes instead of cutting the frame in half and welding a hinge onto it as on other folding bikes. F.I.T. keeps the frame intact and structurally strong enough for military and off-road use. It was a joint collaboration between Montague and General Motors to design and manufacture a HUMMER Tactical Mountain Bike that folds to fit in the back of GM's Hummer H2 and offered in two colors to match the black and yellow models of the H2.
