>hipster, at least in the modern sense, is an umbrella term for people who don't subscribe to the standard mainstream culture.
hipster is the standard mainstream culture today. Just look around.
>the typical urban hipster with his fixie.
"i was biking fixie way before it was cool". 30 years ago in USSR the geared bikes were much less available even if you had money for it - it costs 130 rubles - 2/3 of an engineer's monthly salary vs. fixie costing "only" 64 rubles. Going uphill on a fixie i dreamed about unreachable gears :) With wide availability of geared bikes here biking a fixie in SF is a cool way to beat those self-whipping monks.
Another bunch of urban hipsters on fixies feeling cool :) http://english.people.com.cn/mediafile/200906/08/F2009060815...
