This is a next level bicycle redesign right here. Sadly, it’s only a prototype as of now, but I can’t image this bike not selling if it does actually make it out of the laboratory and into production. The whole Compressedairbike’s frame is the tank for air. How sick is that. There’s a little air-motor placed beneath the seat and you use that valve on the top to control the air pressure. When you run outta air you can just pull into the gas station and fill it up like you would a car tire. The Interweb tells me that with a full take of air the bike can go for 10km. The bike is part of the contemporary International Design Festival in Berlin. More info here.
