The Country's Largest Bike Sharing Systems

In 2011, the total number of cities with bikesharing and the total number of bikesharing stations in the country have more than doubled. How long will Jacksonville wait before becoming the next community to attempt to address mobility by methods other than additional roadway construction?
What Is Bicycle Sharing?

Quote
A bicycle sharing system is a service in which bicycles are made available for shared use to individuals who do not own them. Bicycle sharing systems can be divided into two general categories: "Community Bike programs" organized mostly by local community groups or non-profit organizations; and "Smart Bike programs" implemented by government agencies, sometimes in a public-private partnership. The central concept of these systems is to provide free or affordable access to bicycles for short-distance trips in an urban area as an alternative to motorized public transportation or private vehicles, thereby reducing traffic congestion, noise, and air pollution. Bicycle sharing systems have also been cited as a way to solve the "last mile" problem and connect users to public transit networks.

Before any claims that bicycle sharing won't work in certain areas of Jacksonville, smaller cities like Des Moines, IA are successfully implementing systems in their downtowns and most compact neighborhoods.  Image courtesy of https://bikeomaha.blogspot.com/2010/09/matt-julies-excellent-b-cycle-adventure.html
