BART and Ford GoBike will offer riders free one-month memberships to zip around the Bay Area using GoBikes beginning on Monday.
The deal will include unlimited 45-minute trips for 30 days. The bikes are currently available at 16 BART stations in San Francisco, Oakland and Berkeley.
The regular membership costs $15 per month, and riders will continue into the paid program if they do not cancel their membership.
Both organizations will host signups and offer more information at the 12th Street Oakland BART station at the GoBike dock adjacent to the BART entry and Frank Ogawa Plaza on Monday from 6 a.m. to 7 a.m.
