This tour was so much fun. The electric bikes are a brilliant idea around San Francisco as made the tour so effortless which I really appreciated. Also it meant you were able to actually enjoy the surroundings and scenery without being exhausted from pedalling. Our guide was full of little titbits of information and very patient and calm with those of us who struggle with riding on the other side of the road. We got to see areas that you probably wouldn't cover when visiting the City, so that was another bonus for me.
I would recommend this to anyone and I would certainly do this again if I was ever back in San Francisco.
