Elmoto

The Elmoto is a cross between a mountain bike and a motorcycle. It is powered by a 2KW engine that should last you up to 65km on a single battery charge. The aluminum frame only weighs 45kg, which should allow you to travel at a top speed of almost 45km/h.

Technically, the Elmoto is a "green" vehicle, because it doesn't emit any carbon dioxide. The developers are hoping to sell around 100 bikes before the end of this year. Then, they hope to increase their marketing and go global, to make 2010 a big year for sales.

The Elmoto costs $5,700 and is currently only available in Europe. So, would you buy something like this to help save on gas, or too be more "Green"?
