Less than 5 seconds it took me to cut this lock and the other kryptonite chain I had. That's 5 seconds total!

Damn that sucks to have your bike stolen. I sometimes complain about living in one of the least bike friendly areas possible. Most of the time people have no idea what to make of an adult on a bike. Everybody drives everywhere so even stealing an unlocked bike means you have to have a truck or a big enough vehicle to take it somewhere. And most adults wouldn't even know what to do with a bike if they took one. I've never bothered with much more than a cheap cable lock just to prevent some local kid from rolling away with it on the spur of the moment. That is if I'm somewhere where I even need to lock it at all.

It's crazy to imagine places where you have to worry about people going around looking to steal bikes. I'd be pissed as hell if I had to carry around all that extra stuff just to ride somewhere. I say if you ever find who took it beat the F'er sensless if you are SURE they did it and you can get away with it. Beat them for every biker out there that has to carry five extra pounds of stuff everywhere they go. If someone has actually taken to going around looking to steal stuff they deserve a reality check, for their own and everyone's good.

When every perp carries a power supply and a plasma cutter I wil be very worried... with a good cutoff wheel and a power supply it does not take me much longer to get through a standard Kryptonite lock either.

Statistics suggest that if you lock your bike with a decent quality shackle the odds of it being stolen will be lowered significantly and that most bikes that are stolen from the open are ones that have been locked with cable locks.

Unless you are packing some serious tools a shackle present a time consuming job to cut through it and most theive's greatest enemy is time as the linger you take to steal something the higher the odds you will be be caught.

Thats why there are serial numbers of the frame.

Doesn't sound like they had much time to formulate a thought.

My son has one of those. He got tired of carrying it so he left it secured to the bike rack at his school. After the rainy spring we had it became more and more difficult to unlock until eventually the dang thing wouldn't open. Luckily, it wasn't attached to his bike because neither one of us could get it open. As far as I know, the lock still lies there on the ground to this day, useless.

So be prepared to carry the weight if you get one.

May be WD-40 will help? It may have got rusty from the rain. You could wrap it with plastic bag when not using.

Yeah, but if you're wielding a baseball bat and approaching a suspected bike thief, I don't think you're gonna say, "Hey! Wait a minute!...I need to check your serial number on your bike frame". Detaining him for anytime against his will, is kidnapping. Besides, who's going to just stand there and wait while your holding a baseball bat and looking for some stupid number. Most likely, they're going to protest while standing and they're going to resist your attempt to detain them. It will only escalate from there!

You'll most probably be engaged with the baseball bat. Hope the thief doesn't take it from you and use it against you.

I used so much PB Blaster that is was running out of the lock. The key wouldn't budge. Even after repeated attempts over a few days and leaving the lock in different positions in hopes that the stuff would flow to the right spot. No go.
