San Francisco is buzzing with bike activity, From mixtie townies to hard core mountain bikes to fixies. The local bike scene has been taken over by the rental bikes that so many tourists use. You see throngs of people riding them every where, at the beach and on trails even pushing them up the super steep streets of north beach. I am all for people riding there bikes, but when people have no idea what the traffic laws are or stop in the middle of an intersection to look at a map it gets kind of annoying. The bikes are quite nice, mostly treks and schwinns with disk brakes and racks with locks, all you need to travel around the city. A map and bag for putting things in hangs over the handle bars.
