Imagine if we could make bicycles for just $9 or so. Giora Kariv has done just that. And he is making them from cardboard. Giora was inspired by a man who made canoes out of cardboard.
The secret to the strength of these cardboard bikes, is in the folding of the cardboard, which is described as being folded like origami. This makes it sturdier and it can withstand water and humidity as well.
Hopefully he actually starts selling these soon. It’s a great and cheap way to ride a bike. And if it gets stolen, it’s not as big of a deal since it didn’t cost you as much as a typical bike. Since it is made of cardboard, I guess it is also environmentally friendly too.
