The video above is of Yamaha's very unusual Tesseract concept bike. The Tesseract has four wheels but the appearance is much more like a bullet bike than a traditional four-wheeler. The Tesseract is powered by a liquid cooled, V-twin, 2-cylinder gasoline engine and an electric motor. The clip above not enough for ya? Look below the fold for two more videos of the Tesseract.
The first is from CNET, which questions just who might want a leaning, four-wheeled bike? The second video is a look at lots of the bikes at the Tokyo Motor Show including smaller electric scooters, which is the usual type of electric bike you see. The Tesseract and Crosscage concept are slowly changing our images of electric bikes.
