an exercise machine. (Nice move, because the penny-farthing-from-the-future geometry would make it nearly impossible to ride.) Push the pedals and the epicycloid crank system—a set of eccentric gears like you'd find in a pencil sharpener—spins the magnetized main wheel. This in turn generates a magnetic field and plenty of thigh-burning resistance. Just remember to stop ogling it and, you know, ride.
