This video demonstrates how the location of mass affects travel downhill.
If you want to build a wheel, put as much of the mass as close to the hub as possible for more efficient travel. Here is an old wagonwheel. See how the center is built up? That's not just to strengthen the area around the axle, it makes the wheel work better.
