The Eco 7 Folding Bike is the concept design of Victor Aleman in Mexico. The Eco 7 is designed to be taken on planes and other transportation where space is a significant problem. Once you reach you destination, you unfold your bike and enjoy the great outdoors!
Pretty much every part of the bike is collapsible, including the main frame, the handle bars, crank, brakes, wheels and chain! Once the different elements have been removed from the frame, they all just fold together. The wheels are particularly clever, made from a total of 6 modules where the spokes fold into the rim of the wheel.
No mention of a prototype is mentioned, so I have no idea how long it would take to assemble and disassemble the bike in practice. I have a feeling that it would take around 15 minutes to take the bike apart. My only concern is that the bike might fall apart if one element of the bike was a little loose. That could be painful if a wheel gave way!
