1481.0. "BIKE LOCKS REVISITED" by DSTEG::MCCARTHY () Wed Apr 04 1990 00:10

    
    Along with security paranoid note enter previousy,
    what's the latest in Bike locks?  What do you own?
    Kryponite? Avenir? Uzi with a banana clip?
    
    My cousin who use to live in Boston used a case-hardened
    motorcycle chain with a very (and I do mean VERY) large
    Master lock!!  His bike never got stolen but I think
    he got a hernia from carrying the chain and lock.

                           -< BIKE LOCKS REVISITED >-

    I just read in the latest version of "Bicycling Magazine" (I think! :-))
    that there exists a smaller version of the motorcycle lock called 
    "CobraLinks".  Maybe very similar in weight as your cousin's method.

    The article stresses ease of use as a criteria for what is a "good" 
    lock.  It rates the Kyrponite locks to be "excellent".  

    Me, I have an old Citadel that I used in and around Boston during the 
    late seventies and during the eighties.  I would not feel comfortable
    today with it.  I'm currently in the market for a new lock.  I am 
    seriously looking at the Kryptonite K4 + as a solution to my needs.

1481.2Cable is easierWAV12::DELORIEATime to make the jerseysWed Apr 04 1990 15:538
  I have a Kyrponite cable lock and it works fine. It cost about $15.00 and I
keep it in my seat bag when riding. I like to have the six feet of cable rather
the 6-8 inches of U lock to wrap around something. I use the lock mostly when
I'm out riding with my wife and kids, so I can lock the two bikes and trailer
up with the one lock.

I bring my bike IN at work :-)

1481.3U-lock susceptibilityWORDY::HELMREICHTue Apr 10 1990 14:287
I've heard that some of the U-shaped locks can be broken quite easily.  
A U-lock would rule out amature thieves and ride-away thefts, but pros can pop 
them open.  This would point toward a padlock as perhaps being more break-proof.

1481.4UZI seems the best methodRVNDEL::MCCARTHYFri Apr 20 1990 15:2319

	I called around a few places to ask about case hardened
	chains and massive pad locks to secure a bike (similar
	to what I've seen on motorcycles).  ALL SAFE + LOCK in
	Manchester NH, said that they have been able to cut case
	hardened chains up to 3/8" link with their 2 ft. chain cutter.
	They said that there a 3 ft cutters available so he suggested
	getting in touch with a logging company in Wolfboro NH which
	had a 3/4" case hardened chain and use a Kyptonite lock as
	the pad lock.   The reason this is safe from the bolt cutters
	is that the width of the link is wider than the cutters.

	unfortunately, I can only imagine how heavy that chain would
	be!  The motorcycle store I called suggested Cobra-Links I'll
	have to look into it since U locks are falling from grace  (I
	still have the KYPROTO II lock (the one with the 3" band- Ijust
	don't usually leave the bike out of site)

1481.5Alloy hardened, not caseTOOK::R_WOODBURYFri Apr 20 1990 18:2812
    Sears used to carry � inch alloy hardened chains. I bought one in a
    three foot length. These are alloy steel, hardened all the way through
    and should wreck a bolt cutter. The type of padlock with the protected
    shackle is required to use these effectively. The chain also used to be 
    available in 5/16" diameter four foot lengths. I don't know who
    sources this now. Alloy hardened hoist chain is supposed to be even
    better, and it is available from industrial hardware companies but is
    more expensive. Alloy hardened steel can also withstand those $3
    hacksaw blades with the tungsten tipped teeth.
