A Cardboard Bicycle?

In New York City many more people seem to be riding bicycles due to expensive public transportation fees and because they want to do something to help the environment.

In Israel an inventor has created a new type of bicycle which is not made of any metal parts.  Indeed, most of the bicycle is made out of cardboard.
