Featured in 2008 'The Dark Knight' movie, this bike is tricked out with grappling hooks, cannons and machine guns. The front and rear tires are both a monstrously huge 508 millimeters, and the engines are in the hubs of each wheel. Steering isn't by hand but by shoulder, since there aren't handlebars. Instead, there are shields that fit each arm like sleeves and have the ability to rotate around the bike's frame. The two foot pegs are set 3 1/2 feet apart on either side of the tank, which the rider lies on, belly down.
