This concept was designed for the speed record holders Les Triplettes de Bonneville. French designers from ISD of Valenciennes Charles-Edouard Berche, Ugo Spagnolo , Adrien Fuinesl, Frédéric Dobbelstein, and Jean-Philippe Paries built a motorcycle powered by a compressed air engine. The Saline Bird features carbon fibre frame that holds the air tanks. If you want, you can add a leather body panel to the bike for an aerdynamic finish.
