2010 was the year bikesharing made it big in the US, with the opening of the first large-scale networks in Denver, 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. The list is a lot more impressive than last year’s version.

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

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 CaBi will begin to face more serious competition in 2012 and 2013 as a number of new cities begin to launch their own networks. Baltimore is expected to launch with 30 stations next year, Chicago may build up to 300, and most notably of all: New York is moving forward with a 600-station behemoth system.

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.
