Israeli designer Giora Kariv invented his $9 cardboard bicycle after hearing about someone who'd created a cardboard canoe. The finished product is advertised as remarkably strong and durable:

The Cardboard Bicycle Project is a new, revolutionary and green concept that produces bicycles which are made of durable recycled cardboard.

ERB is an active partner who manages all the business and financial aspects.

The first commercial model of bicycles is designed for large companies as a vehicle for the employees and to large cities as a cheap, light-weight vehicle and parallel to it the electric model is being developed.

The Cardboard Bicycle can withstand water and humidity, coated with a strong layer of brown and white material, making the finished product look like it is made of hard lightweight plastic and can carry riders weighing up to 220 kilograms. The cost to make the bicycle is around $9-$12 and the manufacturer expects that the cost to the consumer would be around $60-$90 depending on what parts they choose to add on.
