A bike needs good wheels, good at rolling. A folding bike is already a compromise with it's small wheels and wobbly frame. When is a bike compromised to the point it no longer rides as a decent bike? If you want transport even more compact, maybe consider a stand up electrical scooter for example? Or design a folding bike not to be more compact, but easier to handle when folded? I like the creativity and the design, but it doesn't strike me as the result of creative minds concentrating on a transport solution.
