Upcycling cardboard into a bike!

This bike is 95% made of cardboard and 100% recyclabe material, and can support riders up to 480lb... The development took three years, two years spent on figuring out cardboard complications. The strength of the bike is based on a "simple" principle: If you fold cardboard once, you are not getting twice the strength but three time the strength!
It's also waterproof and guaranteed to last five years.
Best of all, according to its creator Izhar Gafni, the cost of the Alpha bike would be around $10 per unit!
This is a great upcycling but a bit too much work to try at home.
