2010 was the year bikesharing first made it big in the US, with the opening of the first large-scale network in Denver, followed by even bigger ones in Minneapolis and Washington. That trend continued in 2011, with large new networks in Miami Beach and Boston.

Here are the current US bikesharing systems, ranked by their number of stations.

  1. Washington/Arlington, DC/VA: 140 stations
  2. Minneapolis/Saint Paul, MN: 115 stations
  3. Miami Beach, FL: 70 stations
  4. Boston, MA: 61 stations
  5. Denver, CO: 52 stations*
  6. Madison, WI: 27 stations
  7. Broward County, FL: 20 stations
  8. San Antonio, TX: 20 stations
  9. Boulder, CO: 15 stations*
  10. Washington State University – Pullman, WA: 8 stations
  11. Chicago, IL: 7 stations
  12. Omaha, NE: 5 stations
  13. University of California – Irvine: 4 stations
  14. Des Moines, IA: 4 stations
  15. Tulsa, OK: 4 stations
  16. Louisville, KY: 3 stations
  17. Kailua, HI: 2 stations
  18. Spartanburg, SC: 2 stations

The list is a lot more impressive than last year’s version. Nationwide, the total number of cities with bikesharing expanded from 8 to 18, and the total number of bikesharing stations more than doubled, from 251 to 559.

For the second straight year Washington’s Capital Bikeshare was the largest system, but it won’t be for much longer. A number of new cities will begin to launch their own networks in 2012 and 2013, most notably Chicago and New York, which are planning behemoth 300-station and 600-station systems, respectively.

Data for this list was compiled with the help of The Bike-Sharing Blog’s excellent map of world bikesharing.

* Denver and Boulder are counted separately, but cross-honor memberships. Together they have 67 stations.
