Japan's recent Good Design Expo 2010 was the site for the unveiling of a design prototype called the X-Frame Folding vehicle, an innovation in urban mobility that could ultimately replace the common motorcycle.
Designed by researchers at the Nagoya Institute of Technology, the X-Frame's shape, specifically its seating area, actually changes depending on speed, terrain and number of passengers, and when not in use the entire vehicle folds up vertically for storage. Powered by a replaceable electric battery housed in the vehicle's rear wheel, the X-Frame offers the best in eco-friendly city transport with a minimum parking footprint.
