Cube Urban Street Concept Bike

 

This is the Cube Urban Street Concept Bike designed by Gregor Dauth. You can fold up the full size bike to fit in a Smart car. Continue folding it like the blades of a Swiss Army Knife and the frame will fit into a rucksack. This bicycle concept adds an entirely new frame philosophy to high speed bike design. The Cube Urban Street Bike Concept ditches the seat tube and top story sections of the traditional bike frame for this three-piece system that leaves the back wheel floating. 

                              

Just a shame the wheels don't fold in any way...
