People who want to ride a bike in Charlotte will soon be able to rent a cycle from one of 20 stations in and around uptown. Charlotte Center City Partners was expected to formally unveil Charlotte B-Cycle, which they say is the state’s first bike-sharing program, at an event last Thursday. The first stations have been installed uptown at Trade and Tryon streets and outside 7th Street Public Market. The effort will formally debut in late July or early August. Under the program, 200 bicycles will be available to rent at stations clustered mostly uptown and in SouthEnd. Adults can buy either a daily or year-long membership, and the first 30 minutes of every ride are free. After that, it costs $4 per half-hour. Multiple rentals are allowed each day, and bikes can be returned to any of the 20 stations.
