Remember when we used to sit inside cardboard boxes as kids, and pretend they were planes, trains or automobiles? Israeli designer (and cycling enthusiast) Izhar Gafni takes that whimsical idea one step further by making a bicycle almost entirely out of cardboard — and riding it through the streets!
The upcycled invention (made mostly of cardboard, with real tires and brakes) can support up to 300 pounds and pedals like a regular bike.
Gafni was able to create the sturdy structure by bending, folding, and gluing multiple layers of cardboard together (testing their strength under the weight of cars!), then dipping the components in resin for waterproofness.

Though the bike only cost $10 in materials to make, I think the ingenuity and labor involved to create such a design is worth much more than it looks.
