The greenest transportation around is the bicycle. The problem is that some bicycles are bulky and too heavy for most people. Most of the stores only sell these kind of bicycles. Therefore people have a narrow minded perspective on what is available.

There are foldable bicycles on the market that will fulfill the idea of compact and light. Some of these bikes have set world records as far as being able to fit into buses, yachts, cars and trains.

These bikes have smaller wheels, but are still very fast.
