The route is 8 miles.
A few bigger chains (blazing saddles, bay city rental) but http://www.bikerentalsanfrancisco.com/ Bike Rentals San Francisco has much better online reviews and their prices are good.

I think they are open 8:30-7:30 but would have to double check.
A tip from a reviewer - find a way to "mark" your bike. As in not graffiti, but bring a ribbon or something that you can tie onto the bike so that after the ferry ride back over to the pier, you can IDENTIFY your bike among the stacks of bikes.
The ride might take about 2 hours.
The ferry back from Sausalito costs $9.75 for Adults, and is free for children 5 and under. No charge for bikes, but apparently even with 200(!!!) bike parks on the ferry they do fill up.
Schedule is here http://goldengateferry.org/schedules/Sausalito.php
Next to research what we can do in sausalito. I had thought of going to the National Park visitor centre at Marin Headlands, but on bike I believe it'll be too far/difficult.
