Very little is free in San Francisco, but on Thursday two companies are offering free rides.

To mark the inaugural Global Action Summit in San Francisco, Ford GoBike is offering free 30-minute rides throughout its entire Bay Area network on Sept 13. You can score one of the free passes with the bike-sharing service on the Ford GoBike app.

"Enjoy the ride and help reduce your carbon footprint!" Ford said in a statement.

Scoot is also providing free 30-minute rides on its electric scooters parked around town, and you can take advantage of these on Scoot app.

Business leaders, mayors, governors and activists from around the world are descending upon San Francisco Sept. 12 to 15 for the Global Climate Action Summit. Participants are expected to introduce new ideas to address climate change and pledge trillions of dollars for spending on cleaner energy.
