You Can Buy A $9 Cardboard Bicycle
You’re eyes are not deceiving you. For a mere $9 you can now purchase a fully functional bicycle made completely out of cardboard.
Designer Izhar Gafni has designed the bike to weigh 20 pounds and it can hold a 485 pound person.
Engineers told Gafni that his idea was impossible. Yet he realized that paper could be strong if treated properly. As in crafting origami and tearing telephone books, he explains, “[if] you fold it once, and it’s not just twice the strength, it’s three times the strength.”
The development to what you see today took three years. Two were spent just figuring out the cardboard complications–leading to several patents–and the last was spent converting a cardboard box on wheels to a relatively normal looking bike.
