Since bike owners don't pay taxes on bikes the police aren't interested in helping us out. It's entirely up to the bike community to create an environment that eliminates the bike thief. Beyond the security measures above I can think of lots of creative ways to do this, lots of them. A very direct propaganda campaign comes immediately to mind.
FastJake it sounds like to me there's a equal juxtaposition to your argument: it could be said that the bike thief has beaten you by forcing you into thinking you have to ride a lesser bike. I'd rather track him down with GPS and exact justice, thereby discouraging the bike thief from trying it again.
It seems from many responses that many people have just subscribed to the idea that it's okay that their bike got stolen rather than trying to assuage the problem from the onset. Seems like a sad manner of speaking to me. I don't have that mindset so I don't understand.
