Firstly, do not be put off by hills. The E-Bikes make it super easy. There was 4 of us on the tour, led by the super friendly and knowledgeable Josh who made the trip great. Started off in the new part of town and then went up to the painted ladies, down and up through the Presido, around the Golden Gate Bridge, back through GG park and then Mission, via Haight and Castro. Many stops on the way to look at, and hear about some of the fans instinct history of SF.
Highly recommended.
