The IF Mode Bicycle [$2,500) USD] is a rolling designer's dream. This high-end foldable features large, monoblade wheel mountings, an enclosed trasmission, patented linkage that guides the wheels when folding, a heel push shifter, a Velo saddle, a disc brake, and supple handlebars. Available in black or a striking cream white, and since it can fit in your office/cubicle, it's also guaranteed not to get stolen off a street-side bike rack.
