Lock Weight
 

As the manufacturers do not give it in most cases and a forum search did not turn up anything I thought I would start a thread regarding this. It might help riders concerned with security versus weight make a decision. Please weigh and list your locks.

Kryptonite M18WL U lock weighs about 6 pounds. This is the full size version of the Fahgettaboudit lock and is listed under Powersports on the Kryptonite web site.

Kryptonite NY Fahgettaboudit U lock weighs 4.25 pounds.

OnGuard Bulldog Mini U lock weighs just under 2 pounds.

On-guard Bulldog Standard U lock just under 3 pounds

Abus Steel-o chain 6mm x 2.5 feet - 1.75 pounds

Abus Steel-o chain 7mm x 3.58 ft - 3.25 pounds

they're all heavy.

1.95kg NY FU <too damn heavy, no frame holder, excellent blunt weapon however.
0.90kg evo mini (orange) <too short for most rack applications.
1.15kg evo regular (orange) <not bad, but not that secure for long term, slightly too long.

Anyone have a weight for the New York STD lock? Brute STD (2009)?

I have a hard time believing the Mini U is "just under" 2 lbs. :O)

My kitchen scale says the Kryptonite Evolution Mini LS is 1095g or 2 pounds, 6.6 ounces. That's the lock only, not including the bracket (or key, for that matter). The accompanying Kryptoflex four-foot cable is 342g or 12.05 ounces.

At first, I was going to remark that the question shouldn't be "security vs. weight" and should be "security vs. security" instead.

Then again, if a thief sees a sturdy-looking U-lock or chain, are they going to decide whether to try breaking it because of its brand and model? That is, is a NY Fuhgeddaboutit going to deter thieves better than a U-lock from *-Mart?

At any rate, I don't find myself complaining about lock weight, not unless I'm carrying it on my back over a dozen miles (I've got to find a better way to carry my OnGuard chain if I want to use it again on a long ride).

My Onguard Brute LS 5000 is about 2.3kg according to kitchen scales, packet says 2.4kg 5.2lbs.

Not sure which year it is but its not the current 2009 model.

edit- The packet says ©2004

I find it hilarious it's an NY FU and you say it could be used as a blunt weapon.

NY = New York and FU...well ;)

I run the Kryptonite NY FU and a cheap-ish cable lock for my bike(s). The weight hasnt been an issue if its on the bike, as opposed to on me. And i still have the bike after a year in DC. Though in fairness, she is not a looker.

Which I did today, wrapping it around my Valle's seatpost a couple times and locking it with the lock to the forward bars of the rear rack. Definitely good enough for riding around downtown.

Not sure if I'd put it on the CAAD8 the same way, though.

Ditto, I think it's between 3 and 4lbs.

I'd say that because Kryptonite only warranties the fugeddaboutit in NYC it's probably beefier than their other locks and a lot beefier than a wal-mart ulock. So, yes, the thief is probably going to go after the cheaper ulock first.

I complain about lock weight. A 4lb lock strapped onto a 20lb bike is simply unacceptable. I might as well give up on weight and ride an e-bike if I'm going to ignore 4lbs that's not carrying its weight...

I might feel differently if I parked in many places where bikes are stolen.

You might feel differently if your 20lb bike gets stolen. The bright side of a stolen 20lb bike is that it will now weigh zero pounds.

A new addition to the list:

The new On Guard Pitbull Medium weighs 2 pounds and 6 ounces using the same scale I used for the other locks. This is a Chatillon spring scale. The Pitbull medium is listed as having an opening 3.55" by 6.90", enough larger than the mini U locks in length so that it works with more bike racks, poles etc.

it's too damn heavy, easily 5 lbs

i'll need to weight it out to find out, i'm using it, but never bothered to put it on a scale

I have the Onguard brute STD too and it is like 5 or 6 pounds. I just don't want to risk getting my bike stolen. I have a $500 deductible on my insurance so it would still cost a bit.

Delman, which year is your OnGuard Brute?

why does the weight matter to anyone?

I've weighed most of my locks at the Post Office. The heaviest and largest Kryptonite and OnGuard u-locks came in between five pounds and six pounds. The very lightest u-locks from Kryptonite and OnGuard came in at about two pounds.

When the lock is sitting on a rear rack, the difference between six pounds and two pounds is not a big deal. But, on bikes without a rack, I hang the u-lock on the bars next to the stem...and a six pound lock is VERY noticeable when turning a corner.

OnGuard Pitbull ATB (model 5004): about 2.75 lbs. or 1.25 kg

wow look at the extra weight I don't have to carry.
My bike has never had a lock on it.
At home it is in a lock garage and at work it is 20 feet from my work area..
And no one at work would take the bike because that would require work. And that is not going to happen.

Here is ABUS's website, which nicely includes weights for their locks:

http://www.abus.de/us/main.asp?Scree...3&select=0104b

The ABUS Granite Futura 64 product line appears to be the lightest u-locks available at 726g/1.6lbs for the 6 inch model and 930g/2lbs for the 9 inch model.

Not sure how secure they are, but ABUS rates them pretty high. This seems plausible because they're actually much narrower than most U-locks with a 67mm/2.6" width.

Weight isn't the sole determinant of lock quality. The lock I use is relatively light compared to some that have been mentioned.

Force 3 ( http://www.amazon.com/Master-Lock-81.../dp/B00194D594 ). It weighs 1kg and has a "Gold" rating from the Master Locksmith's Association.

By contrast, the Kryptonite Evolution Mini and Mini LS mentioned above weight the same as mine but only earn a "Silver" rating.

My On-Guard U-lock w/ cable is 5 pounds. Don't remember which model it was.
