For purposes of this list, a multi-modal city is defined by its combination of mass transit, walkable urban places (WalkUP’s), and bike-friendliness.  The rankings below show the top-10 most bike-friendly cities ranked according to how their percentages of transit users and how walkable they are.  While both Tucson and Denver are bikable cities, neither are ranked in the top-10 for transit usage or walkability, making them decidedly less multi-modal urban environments, those which allow the greatest choice of ways to get around.  In another example, Portland ranks first in the U.S. among large cities for bike-friendliness, but its multi-modal ranking is only 5th place because only 11% of its residents commute by public transit.
