Varibike: Pedal with Legs & Arms

Meet the Varibike: a cool bike that lets you pedal with your legs and arms. Riders can use their legs, arms, or both to go fast. The bike has narrow flat handlebars riders can switch to for more stability. It gives you a killer workout and does not seem too awkward. Does it give you a better workout than the Elliptigo elliptical bike? We would love to find out.
