One of the first community bicycle projects in the United States was started in Portland, Oregon in 1994 by civic and environmental activists Tom O'Keefe, Joe Keating and Steve Gunther. It took the approach of simply releasing a number of bicycles to the streets for unrestricted use. While Portland's "Yellow Bike Project" was successful in terms of publicity, it proved unsustainable due to theft and vandalism of the bicycles. The "Yellow Bike Project" was eventually terminated, and replaced with the "Create A Commuter" (CAC) program, which provides free secondhand bicycles to certain preselected low-income and disadvantaged people who need a bicycle to get to work or attend job training courses. In 2016, the Portland Bureau of Transportation (PBOT) launched Biketown, also known as Biketown PDX, a bicycle-sharing system in Portland, Oregon. It is operated by Motivate, with Nike, Inc. as the title sponsor. At launch, the system had 100 stations and 1,000 bicycles serving the city's central and eastside neighborhoods, with hopes to expand outward. There are bikeshare programs throughout the U.S., including Washington D.C.'s Capital Bikeshare, New York City's Citi Bike, and San Francisco's Bay Wheels.
