A couple of years ago we have posted a map comparing some subway systems at the same scale. Based on a similar idea, David Yanofsky has made a very nice map comparing the size of 29 bike-sharing systems around the world. He has used data from an excellent work by Oliver O’Brien with interactive maps including all those cities.
ps. I saw this at Dug's blog (Map of the Week), where he has gathered other interesting visualizations of bike sharing systems*.
