Of course when just "locking around the frame," you are leaving that "one of the most expensive components to the bike" out there and open to quick theft... as easy as loosening the quick release.

Sounds like fun, but DBAN is much less messy and quieter.

Agreed, but I had a pile of about 50 drives to get rid of securely, and some no longer were recognized by the motherboard, yet sensitive data was still on the platters. HIPAA compliance, here I come

If you're walking around with a recip saw, wouldn't it be easier to cut the lock instead of the wheel? That wheel is still under tremendous amounts of force. A recip saw's blade would still bind in it.

Cutting through a rim and a tire while it is under tension is not a fun job with any kind of tool... a thief would have to be pretty motivated to go through that kind of trouble.

And they'd have an un-rideable bike that was missing one of it's key components.

Surprisingly, this one is still around.

I did say it was stolen, it's just not there any more to be the hot bike to lock next to. What surprised me was that the owner never locked the front wheel and, as far as I know, it hasn't been stolen. This is all on a college campus.

A pocket Doberman is also a handy theft deterrent...

a savage attack cat also works

On two different occasions, I've had theives dent or crumple frame tubes in an attempt to bust open my u-lock. They were never succesfull, but now I lock through the rear wheel only wherever possible.

As long as we're talking about some serious cutting, hacking through the pole, street sign, rack, whatever it is locked up to works too.

watch out for poles/racks with stickers on them. There have been instances around LA where racks were cut and covered.

Found an interesting overview of bike theft (methods, prevention, motivations, environment, etc...) from the Center For Problem-Oriented Policing: https://www.popcenter.org/problems/bicycle_theft/

i like this guys locking techique:
https://www.mechbgon.com/lock/index.html

what i like most is that he admit weakness. he know he doesn't have the best setup, and doesn't always lock his bike up the best way possible.

for me i use an old krypto ulok 2 series and an unguard bulldog lock. i lock up back wheel to object and front wheel+frame, if possible to an object too. recently i bought a saddle leash on bikeregiestery, locked up my rear rack+chain stay+saddle. a little bit of peice of mind(it was only 3bucks). i know i should upgrade my pirmary lock, and i have a krypto chain(just hard to carry even with a rack and basket). still i lock up my bike accepting it can get stolen, or parts can get ripped off. but i am happy for each day i can ride my bike.

i want to put a ball bearing in the headset axle nut and on the crankset with some locktight or something. lower the chances of those getting stolen.

As a framebuilder, you'd be amazed how fast I can cut through a frame tube. I could replace the tube and have it ready for paint that afternoon. Just have to buy a new battery for my portable sawzall.

But on a serious note, I've always worried that Sheldon's technique would attract a stupid destructive kind of thief that would only figure out it isn't any easier to steal a bike locked with it after he had done a lot of damage.

weavers & rschafer, those are good links I hadn't seen before. Thanks.
