French designer Jean-Yves Blondeau, also known as “Rollerman”, shows us why all you need is 31-wheels and a steep hill to overtake motorcycles…by surprise of course. His “suit places a number of rollers (similar to those found on rollerblades) on most of the major joints, the torso, and the back. The wearer can ride in a variety of positions (upright, prone, supine, on all fours, etc.) at speeds of up to 70 mph (116 km/h) in downhill.” Video after the break.
