But I think a less trollish way to put the idea is: bike locks aren't full proof, somebody can steal other bike parts even if they can't get your bike, and it's best never to leave your bike by its lonesome, if that's possible. For example, my road bike is a free spirit, and doesn't like being tied down. I love that bike too much to risk locking her up. Instead, I go for rides, but only leave her unattended inside my house. Anyway, that's the non trolling translation.
