Welcome to the Bay Area, I live and work in San Francisco. Commute to work 3 times or more a week on my bike. It is 22 miles round trip from my house to the office. On the weekends I ride in Marin with the Sports Basement Group rides, Mount Tam, Paradise Loop, Alpine Dam all great rides. Anywhere in the bay area is great to live. My family and I love it.

If you are young and single, there's plenty of entertainment, socializing and just about something for everyone. If you live out of town (I.e. outside of SF) then more than likely you'll be coming into town for events. As for biking, there are pro's, semi pros, advanced amateurs you get the idea just about every level of cyclists. Young and old are on the streets and road.

San Francisco has its own bicycle coalition. Check it out at http://www.sfbike.org/, if you are young and fast check out http://missioncycling.org/ I old 59 and slow but no matter they are a great bunch of guys and girls.

Where ever you live you are going to like it. Just remember we have a Mediterranean climate rain in the winter, November through March then sunny for the rest of the year. We ride year around.

Enjoy yourself.
