Enjoy a full length video from Dirt Rider Magazine. Intelligent Energy's ENV (Emissions Neutral Vehicle) motorcycle is powered by a hydrogen gas fuel cell, with an electric belt-driven final drive. The ENV puts out about six horsepower with a top speed of just over 50mph. The bike gets about 100 miles per tank (which costs about $3 to fill), and has only moist air coming out the exhaust. Listen to that "Jetsons' car" sound as Jimmy Lewis takes it for a spin! When you’re done you can browse our video library to watch all of our high quality videos covering a wide array of topics.
