The Lean Mean Green Machine is a nine-foot-long, gas-powered tricycle, an adult-sized homage to the iconic 1970s Green Machine toy. Its 45"-diameter front wheel, said to be the world’s largest motorbike wheel, is driven by a chain from an air-cooled Harley-Davidson Evo V-twin that produces 60 horsepower and reaches a top speed of 50 mph. The rider steers with two handheld push/pull levers that turn the two rear wheels and also engage the brakes, while a foot lever shifts the manual six-speed transmission, and an 8 1/2-gallon fuel tank built into the frame provides a range of up to 400 miles.
