From Market St. to Ocean Beach, the San Francisco ‘Wiggle’ is a wonderful bike route that avoids all the hills and passes through some of the city’s most beautiful spots.  I personally love to take this route on Sundays because that’s when Golden Gate Park closes some of its roads to cars so that bicycles and pedestrians get free rein. Sunday is also the day that delightful characters hold a roller disco dance party, Lindy in the Park has an all day swing dance sessions, and Park Chalet typically has live music on display.
