Take a look at the bicycle in the picture above. This is a fully collapsible bicycle designed by Mexican industrial designer Victor M. Aleman. Named 'Eco // 07', this beautiful urban bicycle is designed to save space when it is being transported or when not in use. But, wait! This is not an ordinary bike. Most parts of the bike, including the wheels, can be folded. Don't believe me? First take a look at the pictures.
Eco // 07 design consists of two systems - Wheel folding system and Bike Structure system. The Wheel is composed by six modules, each one has a double pivot in the joints, this allows the wheel to fold and become smaller, the spokes are contained in the inner structure of the wheel, when you unfold the system, the spokes rotate to the center of the mechanism where it attach to the center of the wheel. The double triangular bike structure is composed by expandable modules, each one collapses to a smaller dimension and then this modules align by the rotation of the axis in the joint of the structure, to keep in position all the structure is used an special part in a form of an X that aligns all the modules to their position.
