Capital Bikeshare is the best bike-sharing system, ever. But where are all those bikes going? A new data visualization map from Mobility Lab offers some answers.

The map, which uses data from Capital Bikeshare’s third quarter of 2012, draws lines between a station and where its bikes most frequently end up. The Massachusetts Avenue NW station near Dupont Circle comes in as the most popular, followed by the 15th and P Street NW dock and a station outside 14th Street NW’s Reeves Center.

Another interesting Bikeshare factoids from Mobility Lab: The average distance between the station a bike leaves and where it ends up is about 1.2 miles.

According to the data, users who buy one- or three-day passes make up 20 percent of Bikeshare trips.  Unsurprisingly, those casual users tend to stick to the Mall.
