Recycled Cardboard Bike
Environmentally friendly, strong, and extremely cheap ($9!) - via Made In Israel:
They are made of recycled cardboard, can withstand water and humidity, cost nearly nothing – and might the concept of green vehicle. Izhar Gafni is a Kibbutz resident, who decided to prove to his fellow engineers that he could make a bicycle at nearly no cost.
“They said it was impossible”
Izhar Gafni, originally from Kibbutz Bror Hayil in the Negev, took the most popular and widely sold vehicle in the community and decided to turn it into an entirely green private venture.
Gafni’s bicycle redefines the idea of green transportation in every way, being environmentally friendly from early stages of production all the way through creation of the final product. The bicycles are made out of recycled and used cardboard.
… Gafni said that the production cost for his recycled bicycles is around $9-12 each, and he estimates it could be sold to a consumer for $60 to 90, depending on what parts they choose to add.
Here is a 6 minute video, where the inventor guides us himself how this project came about:
