Rotating weight is really great, as long as you are riding at a steady rate on a flat road, or downhill. But the heavier the rotating mass is, the more energy is expended to increase speed, regardless of how fast you are going. In most real world applications you're not riding along at exactly the same speed.
And when the world tilts up, you start paying to maintain that speed.
Think about the big rig you were following at 75 MPH until you hit the first hill...
