Mexico City: For Ecobici, Mexico City actually repealed their law requiring cyclists to wear helmets. Not that that's a good idea, but they're trying to get this huge program off the ground. Over 1,100 bikes at 82 stations around the city have bikes available for a $23 annual subscription with a free first half-hour, an 80-cent next half-hour and $2.70 per hour after that. They plan to have 6,000 EcoBici bikes soon. [Ecobici]

Washington DC: Smartbike is the name of the DC area's sharing system, and it comes from Clear Channel and the city's Department of Transportation. Over 1,100 bikes at 100+ locations in both downtown DC and Arlington, VA are up for rides. An annual subscription for unlimited rides is $40. [Smartbike]

Cities that should launch their bike sharing programs any minute now: Toronto and Boston. Cities that should have bike sharing systems by now, but are woefully behind: Chicago and San Francisco.
