Engineer designer Giora Kariv has created a $9 cardboard bicycle. And yes, it actually works.
According to Geek.com, the bike costs about $9 to manufacture, weighs about 20 pounds, can hold a 485 pound person, can withstand water and is made out of cardboard.
“It is always exciting to take old materials and turn it into something completely different. Something useful.”
Kariv said that he was inspired to make his cardboard commuter when he heard about a man who made a canoe out of cardboard. Kariv was inspired by the man’s ingenuity and decided to try and create a cardboard bicycle.
“This canoe made out of cardboard was sitting in the back of my head and I just couldn’t let it go. Then it struck me: Why not make a bicycle out of cardboard.”
Kariv was told by three engineers that it would be impossible. His wife, however, encouraged him to try and create his bicycle.
The bike designer said that there isn’t a lot of information about constructing objects, besides boxes, out of cardboard so he had to do a lot of trial and error.
In the end Kariv was able to create his bicycle out of about $9 of cardboard. The wheels, the seat, the frame, and the handlebars are all made out of cardboard. Kariv believes that stores could sell the bike for about $60 but said that the real value of the bike is to promote recycling, green transportation, and exercise.
