Eureka Magazine has a profile of this sweet ride, the whole thing ???printed??? from laser-sintered nylon powder.
The ???Airbike??? is made of nylon but, according to EADS, is strong enough to replace steel or aluminium and requires no conventional maintenance or assembly. It is ???grown??? from powder, allowing complete sections to be built as one piece; the wheels, bearings and axle being incorporated within the ???growing??? process and built at the same time. Because it can be built to rider specification, it requires no adjustment.
