More than just a sculpture, this fully-functional bicycle was made with a 3D printer. To be more specific, "scientists in Bristol designed the bike on a computer and sent it to a printer, which placed layers of melted nylon powder on top of each other to build-up the machine."

Individual components such as gears, pedals and wheels are usually made in different factories and assembled into a finished bike but the Airbike is a single, complete part.[via DailyMail]
