San Francisco Bay Area riders could have thousands more bicycles to share.

City leaders hope to expand the Bay Area Bike Share program from 700 to 7,000 rental bikes, including new bikes in Berkeley, Oakland and Emeryville by 2017.

The number of bikes in San Francisco would jump from 328 to 4,500. San Jose would go from 129 bikes to 1,000.

Riders pay a membership fee to check out bikes for short rides, returning the bikes to self-locking kiosks. Trips longer than 30 minutes incur overtime charges. Washington, D.C., and New York City also have bike share programs.

The bay area bike pilot program launched in 2013. The Metropolitan Transportation Commission could approve the contract later this spring.
