I'm currently working on a cardboard bike project with my local Bike Collective and the Science station. We're going a slightly different direction than the guy in the above video. We're laminating multiple sheets of corrugated cardboard together in a vacuum bag, and siphoning fiberglass resin into it. The result is like plywood, but a little lighter. It's plenty stiff. We're using salvaged bike wheels, handlebars, fork, seat, etc. to simplify the project.
It may just work. I'll make a post on it later this month when we're done.
It's a pointless engineering exercise, really. It's not very "green" because we're using nasty resin. Recycled steel and aluminum frames are more "green". But it's a fun exercise.
