[net.bicycle] Serious Locking for Bicycles

tierney@fortune.UUCP (Charles Tierney) (02/06/85)

I have a rather nice 2 year old Ross Mountain Bike.  It lives 
in San Francisco and is very happy (and unstolen).  One of the 
reasons (presumably) for it remaining mine is the lock I use.

I use a Kryptonite K4 lock.  These are *serious* locks.  My K4 
cost $28 with a nice vinyl covered (no scratches) holder which 
fit easily on the frame downtube.  It takes a professional to 
get through a Kryptonite K4.  No kidding.  (Cutting torches work. :-)

I also lock my bicycle to a handy steel pole (parking meters are best)
whenever I am out of arms length of it.  Crazy?  It only takes
30 seconds to put the lock on the bike.  Takes far less to grab it.

And I still have my baby!

Locks are to keep honest people honest.  I have been told by someone working
in a bike shop that there is a very simple and quick way (takes about 1
minute) to break the type of locking mechanism whick Kriptonite uses.  Also,
a friend of mine sat down one evening and made a 'pick' for the type
of lock Kriptonite uses.  It took him about 5 hours to make the pick, and
about 2 minutes each to open three locks similar to the Kriptonite (he
included a Citadale bike lock in his demonstration).  The only truely safe
place for the bicycle is on your insurance, which often requires that
it be locked when stolen.

Be careful about using parking meters to lock your bike to.  I've heard
(hearsay) that some thieves find ways to remove the parking meter heads and
then just lift the bike off.

Looks like it's time again to trot out the
"Constant bicycle weight" theorem       :-)

THEOREM: All bicycles weigh 50 pounds.

PROOF: A 20 pound bike needs a 30 pound lock.
A  40 pound bike needs only a 10 pound lock.
And a 50 pound bike needs no lock at all.
(Except maybe at USC?  :-)  )
