The Skizee is basically a motorized tread that you hold onto and use to propel you over flat terrain. No longer is ski propulsion the exclusive domain of gravity; you get motor-powered skiing. Powered by a 10.5-hp engine with the handle-mounted electric start and tear those flats as if they're pointed 45 degrees. It's like a personal, mini-snowmobile, watch the video of this thing in action. The Skizee will set you back $2,500, a set of skis are not included.
