Hint #2 - Totem Pole Bike rack handles bikes large and small!

Hint #2:  When loading shorter bikes and longer bikes, load the shorter bikes first.  Adjust the skewer bar so that the rear wheel rests on it behind the rear axle.  The larger bike will benefit from the fact that the top bar is angled up, and will still catch the rear wheel of the larger bike, forward of the rear axle.
