A new public-private venture called SmartBike in Washington DC plans to make 120 bicyclesavailable at 10 spots in central locations in the city. According to the New York Times the automated program, which district officials say is the first of its kind in the nation, will operate in a similar fashion to car-sharing programs like Zipcar. You become a member, then rent a bike with a swipe of your card.
My sister, who lives in Chicago, is a big fan of Zipcar. So maybe this would work too, though I have a feeling, not in Colorado Springs.
