The same people who put together the WalkScore for rating walkable communities have now turned their attention to the bicycle, and boy did DC do well. DC finished 6th, with an average BikeScore of 65, about 14 points back of leader Minneapolis and 5 points back of #2 Portland.
The score is a calculation based on hills, bike commuters, bike infrastructure (bike routes, bike lanes, cycle tracks, bikesharing and destinations for cyclists. DC does pretty well on the hills front, Rock Creek Park and the Palisades notwithstanding, and scores pretty high on the Destinations and Infrastructure scores. With more cyclist commuters, DC could easily move up toward San Francisco and Portland, tied at 70.
