I clarified as best I could. Here is the original text from the previous edit

A bicycle lock is a safety device used on bicycles to prevent theft. Putting and handle and rope locks are used.

==Putting lock==

A putting lock is a fahrradschloss, which consists of a lockable metal pin. It prevents a rotation of the Rades in the final condition. Putting locks cannot prevent a theft by carrying away the bicycle.

==Buegel lock==

A buegel lock is a bicycle lock, which consists of a usually flexible metal ring, which is led by the spokes and the frameworks. Since this handle can be wound also around firm of objects, it is possible with a buegelschloss to secure bicycles also against carrying off. Buegelschloesser offer a higher protection from thefts. In contrast to putting locks buegelschloesser are used also as zahlenschloesser.

==Chain lock==

A chain lock is a lockable chain. A chain lock is like a buegel lock available as key or number lock. Chain locks are also used for securing other transportable things from theft.

I have no idea what a Buegel or lock or a Putting lock is. There's a lot of german looking words here. If someone knows what these are, and wants to add them back in a clear and consise manner, that's fine by me. Additionally, this entire entry should probably be in Wiktionary. The section on chain locks strikes me especially as a blinding flash of the obvious. DaveTheRed 06:10, 16 Feb 2005 (UTC)

I think we should have a different image at the top, one where the lock is doing its job? :-> The lonely wheel could be later, illustrating a discussion of how to properly lock a bike. --Christopherlin 09:55, 27 December 2005 (UTC)

[edit] 5 != Hex

Five-sided hex key skewers exist... Hm. Five-sided pent keys may be. Or possibly five-sided Allen Keys 91.4.206.122 22:35, 11 April 2007 (UTC)

[edit] Liquid Nitrogen

I think the original editor's claim that "freone" is used to break U-locks is dubious considering he couldn't even get the word right. At any rate, I think he meant 'liquid nitrogen,' as Freon isn't even cold as it is normally stored. Liquid nitrogen is a very expensive and exotic way to break a lock as much more sensible methods (such as using a grinder) exist. I rewrote that section. I also removed the reference to "Kryptonite U-Locks" as the picture already is of a kryptonite-brand U-lock and the Kryptonite mark is also used on chain and cable locks. -- Jorbettis 07:20, 15 November 2006 (UTC)

Is the "liquid nitrogen used as a lock-defeating strategy" claim even verified? Urban legend?

If I remember my high school chemistry correctly all compressed gases absorb heat when allowed to expand. (It's not so much that they become cold as everything around them becomes cold) Some gases are handier then others for refrigeration purposes in that they aren't flammable or poisonous. -Dhodges 14:45, 13 January 2007 (UTC)

While liquid nitrogen should theoretically make a lock brittle enough to shatter it, the fact of the matter is that it requires the metal to be dipped in the liquid for a period of time. It is an incredibly dangerous material to work with and you would need a lot to successfully freeze a lock to a shatter point. If someone wants to add it back in, I strongly suggest finding a reliable source to cite, because I've tried it and it didn't work on my Kryptonite lock, though I wish it did. --SquatGoblin 03:16, 23 April 2007 (UTC)
