The rocking motion increases the force applied to the pedals. The point I'm making is that of the force applied to the pedals only some of it (most of it, granted) goes to moving the bike forward. Some of it goes to overcoming aerodynamic drag, rolling resistance, friction/ heat loss, and overcoming gyroscopic inertia.
