A pilot program set to launch May 2 will introduce bike sharing to Houston's city center.

H-Town is one of only 15 U.S. cities to develop such a program, which will be known as Houston B-cycle. To prove the concept, the program will start with just 18 bikes at three stations including City Hall, the George R. Brown Convention Center and Market Square Park.

Here's how it works. Houston B-cycle will be a membership-driven program, with individual memberships available by the day, week or year. Members have unlimited access to the bikes from 6 a.m. to 11 p.m. daily. The first 90 minutes of each usage are free and members can check out the bikes at the various stations and return them to the same station or one of the other two.

Houston's program will be managed and operated by the nonprofit Houston Bike Share. For more information, visit Houston B-cycle. P.S. riders are encouraged to wear their own helmets. Don't forget!
