The compactable bicycle concept was driven from the need of boosting urban space efficiency when it is not in use or being transported. The wheel is made of six modules, each with double pivot in their joints, allowing the wheel to be folded and become smaller. The spokes of the wheel are contained in the internal structure when you fold the bicycle and the spokes rotate to the system’s center where they attach with the center wheel.
