Relay Bike Share moved into Atlanta last summer. There were about 100 bright blue bikes around town to choose from and 10 rental stations. Now, there are 500 of them at more than 70 bike rental stations around the city. Timberley Jones, Relay’s director of community outreach, said there’s been a change in Atlanta’s attitude toward bikes. “It’s just about letting more people see bikes in different areas of the city, and letting cars know that we are allowed to navigate these same roads,” Jones said.
