This highly functional bicycle only costs $20 and is made from cardboard. I know, right? Engineer and Inventor Izhar Gafni was told it couldn’t be done, but he proved everyone wrong. Made mostly with recycled cardboard (plus some melted recycled plastic and car tires) the surprisingly durable bike is fire and water resistant and holds up to 300 pounds.
