 great cheap lock - Sep 17, 2010

not as tough as some of the krypto models, but a theft deterrent for sure. Run the 4 ft cable thru your seat.
The key is a little awkward

 Good lock - Sep 10, 2010

I live in DC where bike theft can be rampant in some parts...the lock has held up and my bike is still with me so far! Great deal too.

 Perfect! - Aug 19, 2010

Received the lock in record shipping time and it looks great! Thanks for helping to keep the bike safe and making it affordable to do so. Everyone recommended the Kryptonite U-locks and I'm so happy I listened to them and ordered from here instead of in stores. Also, super happy I ordered the one with the 4 foot flex cable-it makes it a breeze to lock up even in awkward places and I know my bike is safe and sound!

 Great lock for a great price - Aug 14, 2010

This lock is great. I live in a large city and go to a HUGE university (Ohio State), but since I ride an older road bike, bike theft isn't that big of a concern. If you have a new bike, live in a bad area, store your bike outside, etc, I would recommend the New York series lock, but in my situation that would be overkill. To be honest this lock is probably a little bit of overkill based on the other types of locks I've seen around campus, but better safe than sorry.

The keys are somewhat flimsy, but no worse than with any other u-bolt lock I've owned. Kryptonite offers one free set of replacement keys when you register them online (no cost for registration), so unless you think you'll break 4 keys I wouldn't worry about it. I don't use the lock mount, but it looks like one's I have used in the past and all of them broke within a few days. You might as well save yourself the extra weight on your frame and put it in a bag. The added cable is awesome! I can lock my front wheel for complete security or lock a few of my friends' bikes up with mine when we go out for a group ride.

 Does what it is advertised to do - Aug 05, 2010

The U-Lock portion is strong enough to deter thieves, and the cable lock that goes with it is long enough to connect your tires to the U-Lock and bike parking rail. The mount is a pain to install and I do not use it. The Velcro tab on the cable lock is a nice touch that allows you to wrap it around the U-Lock for storage. The hole doesn't seem very sturdy, but it should last *knock on wood*.

 Definitely a good luck - Jun 15, 2010

I love this lock. It's very reliable and the cable is very useful to tie your seat to it if you have a quick release one. It was to big but if you attach it to the vertical bar of your bike with a slight angle (you can adjust it) it won't bother you. At first uses you will hurt your hand pulling it out of its place but it gets better and it is also easier if you open the lock and then pull out the U part.

 Great value for a nice lock and cable set... - Jun 04, 2010

This is a great bike lock/cable combo. It's larger than I expected which really has been a good thing since I have never had a problem securing my bike with this lock. It also cam with a mounting bracket so you can attach it to your bike frame and not have to carry this in a back pack. I am very happy with this purchase and would buy again.

 Great, reliable lock system - May 19, 2010

Great lock, secures the bike and the wheel with ease. My neighbor had a high-end cable lock (no u-lock) and used it to secure her bike to her porch rail three days ago. The cable was cut last night and the bike is already gone. Drop a few bucks for this set. Cheaper than a new bike.

 My bike is not yet stolen - May 10, 2010

The mount sucks, but the lock is solid and so far my bike is still in my possession.

 really good lock - May 03, 2010

I wanted to have a really good lock, because by old bike got stolen and a lot of other bikes in my area too. so I bought this one and the OnGuard Bulldog MINI DT, because I thought it is better to have two not too expensive locks than one really expensive. The bike before also had a quite expensive lock, but still got stolen. But now I only use both locks at night. This one is totally enough to lock it during the day. Nearly everyone in my area uses this one now.
And though it is quite big, it is not too heavy to carry it with you. I always have it hanging on my handlebar while riding.
Best buy for this price!

 Effective - Apr 24, 2010

Works good so far. Seems ot be well made. Skeptical based on comments on this and competing models.

 Good lock, scammy protection offer - Apr 23, 2010

I like the lock. It's for a cheap ($100) bike. When I get a more expensive bike I'll buy the New York Std (yellow sleeve) lock.

I think the Kryptonite locks are a good value. But, the "protection offer" is almost insulting to my intelligence. You have to read the box carefully to realize you're only getting an *offer*, not protection. You can buy protection for 1-2 years. And, the terms of protection are so ridiculously tedious that you wonder why they even offer. The terms sound like they don't want you to use it.

Here's an example: You have to register your keys and serial number of your bike within 15 days. Why a time limit? I bought my lock before receiving my bike. Why should it matter to Kryptonite that I bought the lock 2-3 months ago?

Also, you can't transfer the lock/insurance to another bicycle. Why would Kryptonite care about that? Unless it's just a gimmick to sell more locks?

For a claim, you have to submit the broken lock. What if the thief takes the evidence with him?

I've heard that NYC messengers who ride expensive bikes buy two locks. They take one to a welder to cut/break. They register the keys (and buy protection) for that lock. They use the other other lock. If their bike is stolen, they submit the broken lock which they never used.

I can't blame them for doing that. Kryptonite sets the conditions that you almost have to do that if you want to protect a $1200 bike.

I would give the lock 5 stars. But, because of the fishy "protection offer," I only gave 4.

 Kryptonite lock - Apr 08, 2010

Does the job. Cumbersome however to mount on the frame. Easy to use,no problems.

 Lock is jammed..... - Apr 07, 2010

I bought this lock 2 months ago and its jammed inside and I can't lock it....

 lock is jammed - Apr 05, 2010

I just bought this lock and I used it two times and the lock is jammed. Maybe I got a faulty lock...I am not pleased.

 The Lock - Jan 30, 2010

Delivered in a very timely manner and performs very well. The attaching mechanism is difficult to use but otherwise is excellent.

 Brings peace of mind. - Jan 27, 2010

I was using a cord type lock before, but when I got a new bike I knew I had to step up protection. I feel safe whenever I leave my bike locked up with this Kryptonite U lock. Also, the lock opens very smoothly, and although the attachment piece was a little weird to fit on bike it now serves its purpose well.

-If your looking at locks, buy this one. It is fairly cheap and works very well.

 Sturdy, but took getting used to - Jan 09, 2010

Now that I have the Kryptonite U lock and cable, I feel very comfortable leaving my bike parked at a bike rack on my school's campus where bike theft is common. It took a little practice getting used to locking and unlocking quickly as well as figuring out the best way to carry it while riding my bike (it's a bit heavy), but I would buy this same product over and over again and recommend it to anyone who wants to keep their bike safe from theft.

 Good solid lock... always happy with Kryptonite. - Nov 02, 2009

This is my second lock from Kryptonite and they are they only brand of bike lock I will use. I've had my bike lock for 2 years now and have never had any issues. Easy to use, this one is especially nice because it comes with an attachment so you can secure your lock to your bike while you ride and the cord allows for greater flexibility in where you can lock your bike up. I highly recommend!

 Good product - Sep 12, 2009

Good product. Only the mount could inspire a bit more confidence, but seems to work.

 Serves its purpose - Sep 03, 2009

This lock works well. It is a little heavy, and I could not attach it to my bike anywhere, so I carry it in my pack. The cable makes it much easier to lock my bike to various racks, and makes it so I can lock up my friends bike at the same time. I would buy this again.

 Great product - Jun 18, 2009

I live in New York and as it's well known, bikes don't stay long in the same location! I left my bike for more than 3 days locked with this lock and found it right I left it when I came back! The additional cable is good and nice for the price. Hate the so called eazy mount though...

 it's not bad for medium to low bike crime areas - Apr 25, 2009

Kryptonite STD U Lock seems to be a decent lock but it still can be "infiltrated" by a knowledgeable master thief/master lock picker in probably under 1 hour time. I'm not too worried since it is sizable, hefty looking and very heavy (4 lbs), so it looks bigger than what I saw on other bikes in the bike rack and my bike is only valued at $285.

The keys are very flimsy and forged with cheap metal so I won't be surprised in 2 months that they snap or are damaged. The Lock holder (cheap plastic) didn't work on my bike as the Lock is too big to fit anywhere so I just snug it into my rear rack. Comes with a cable (be warned, it can be cut quite easily so don't use it as a "main attachment" to a pole, bike rack, etc, just use it to secure your rear or front tires with the U Lock attached to a pole, bike rack.).

In all, it's not bad for medium to low bike crime areas but don't use it for expensive bikes, big cities, dangerous zones or in dark desolate areas where a thief can use high powered tools or torches.
