Green Machine
A gas-powered, adult-sized big wheel? Count us in. The Green Machine ($75,000) is categorized as a three-wheeled motorcycle, but its looks — inspired by the classic pedaled tricycle of the same name — scream out "toy", even as its Harley-Davidson v-twin Evo engine pushes you along at speeds of up to 50 mph. Other features include a six-speed transmission, a range of 400 miles, and the ability to attract ridiculous amounts of attention. [Scouted by Scott]
