At times it only takes the extra motivation of being told “you can’t” to fuel the building of something amazing. At least that’s how it seems to have worked for Izhar Gafni. Inspired by a cardboard canoe, he decided to invent an entirely cardboard bicycle, despite being told by other engineers it would be impossible.
Gafni, determined to prove them wrong, spent years learning precisely how cardboard and the appropriate cardboard-building tools work. The result is a functioning, all-cardboard bicycle that costs only $9 to build. Did we mention it’s water-resistant?
If you want your own cardboard bike and you don’t want to learn cardboard craftsmanship and engineering, one of Gafni’s creations will probably cost you closer to $60 when they reach the market.
