Just read the thread about thiefs caught.
I am really scared that mine is not safe enough after reading this.
I basically have a metal chain and a separate lock to close the ends.
I heard the lock is usually the weakest link and easy to brake.
What lock would be really save?
I'll probably get a Kryptonite U-Lock for work, where I leave the bike for most of the day, but for the city, shopping and restaurant or gym stops, I'd like to carry a little lighter lock with me.
