Jag såg ett inslag på BBC News om det här. Cykeln såg fräck ut, men den hade nog rätt mycket av Iterans svikt. Och ljudet från frihjulet när journalisten cyklade några meter i studion var som om hela härligheten skulle braka ihop. Fast det var ju TV, jag vet inte hur rättvisande det var. Länk till klippet här: http://www.bbc.co.uk/news/uk-12664422

Ser väldigt intressant ut :)
Styrgeometrin gå nog att förbättra dock..

Jag vet inget men läs mer om det här
Engineers from the Bristol wing of the European Aeronautic Defence and Space Company (EADS) have announced the development of the first bicycle using Additive Layer Manufacturing (ALM) technology. The manufacturing process involves "growing" the components from a fine nylon powder, similar in concept to 3D printing. Said to be as strong as steel, the end product is claimed to contain only a fraction of the source material used by traditional machining, and the process results in much less waste.
Lika starkt som stål säger de men väger mindre för samma styrka?
Verkar ju kul.

"The possibilities with ALM are huge it's a game-changing technology," said Andy Hawkins, the lead engineer for ALM at EADS. "The beauty is that complex designs do not cost any extra to produce. The laser can draw any shape you like and many unique design features have been incorporated into the Airbike such as the auxetic structure to provide saddle cushioning or the integrated bearings encased within the hubs."

The Airbike requires no conventional maintenance or assembly, and also benefits from a Kevlar belt drive system, integrated bearings encased in hubs and crank, and embossed text in various locations, all of which were produced as the bike was formed.
The ALM technology used in the development of the Airbike is at the proof-of-concept stage at the moment, but EADS says that it has reached a level of development where it can be used in high-stress, safety-critical aviation.
