[net.bicycle] Theft Resistance of U-shaped bicycl

hosking@convexs.UUCP (06/29/85)

I've decided not to get any of the U shaped locks  because there just
don't seem to be enough places to use them around here.  They seem to
be fine in some cases, but often the only convenient thing  to lock a
bike to is a telephone pole, flagpole, tree, or  other large diameter
object.  U-shaped locks don't work  well in  such cases.   I'd rather
have a less than optimal lock which is in  use than  a wonderful lock
with no place to use it.

I've heard tales that a Kryptonite can be broken using liquid nitrogen, which
is much more believable than dry ice.  No proof for this, though.

Yes, it's nitrogen. It's not the lock housing, but the internals that shatter,
springing open the lock.  We had a rash of these at college -- "unpickable" 
locks with shattered insides, and it was a chemistry prof who solved the 
"mystery".
