A very cool design concept. Now if they can make them out of paper and epoxy you could build something out of a sci-fi book. 4.1 pounds of pretty nice weight for something that should be darn strong. I once had a Fuji Sun Tour bike that weighed in at around 25 pounds and I would have been quite happy to drop a few of those if somthing like this would have been around back then.
Bamboo bikes are in production at Calfee Design.
