The attitude of many cyclists in this city needs improvement, but there are lots of organizations in the city that do their best to help out new cyclists, like the Bicycle Coalition and the Bike Kitchen, and on Bike to Work Day you can find a lot of really helpful people.
I can't see the appeal of riding around in lycra and helmet, fantasizing about being a racer though. Bike is just an alternative form of getting from A to B, pleasant in mild weather, on relatively flat roads and over not to long distances.
I find even at VC it varies from employee to employee; some are super-friendly and helpful while others are a little stand-offish.
And heck SF has the excellent bike kitchen (http://bikekitchen.org) which is probably the friendliest place for bike newbies on earth. You can get a working bike for $0 with a little time and effort.
but yeah, everything else is consistent with your experience. bikers are jerks.
Well, I think in this case you can compare the cycling community (in some places) to the Ruby community. They want everyone to ride fixies (or whatever the trend du jour would be), and if you dare suggest that your needs are better satisfied by some other solution, they will tear you apart with great enthusiasm.
Of course, they could just be dicks and say they don't care if other people start cycling. In which case, they don't get to wear helmet stickers touting their "zero emissions vehicle" or complain about SUV drivers.
Either they need to be more friendly about getting more people on bikes or stop sneering at people who don't have them. They can't have it both ways.
I live in San Francisco, and about a month ago I decided to buy a bike, the first time I'd bought a bicycle. I know how to ride a bike, but I am in all other ways a noob -- I've never owned a bike with gears (the last time I had a bike I was 12), know nothing about road bikes vs. mountain bikes vs. hybrids, etc.. Surely, in a city as self-consciously eco-friendly as San Francisco, I could find a bike store full of earnest, well-meaning hippies to point me in the right direction for planet-saving happiness, preferably on a budget?
No such luck. I walked into store after store to be greeted with barely-disguised contempt as I explained I had no idea what I wanted, just "a bike to ride around on", which turned into sneers of disgust when I said that I wanted to spend less than $500 on it.
Even co-workers who bike were of little help. One described buying a bike for less than $500 as "like buying a netbook". I countered that a netbook was a great analogy, as I wasn't going to be commuting on the bike, just riding it every so often, the cycling of equivalent of "just checking my email".
Eventually I got my bike (at Valencia Cyclery) and I'm enjoying it very much, but it's easy to see how people can be put off. Any cycling is better than no cycling, and "bike people" need to get over themselves and be more welcoming to the new and clueless.
