Because the world is not flat, and because it forces you to move your legs all the time. It makes you pedal hard up hills, fast down hills, hard to accelerate, against the pedals to slow down. Try going out on your geared bike. Pick a high ratio, say one that's comfy at 17mph. Now don't shift during your entire ride. Then imagine moving your legs whenever the bike is moving.
