Questions & Answers

Is this a 9" lock (as the product title indicates) or an 11" lock? 5"? Thank you (as specified in the specs). ?

When closed, the U is about 11" long and 9" wide on the inside. So you have 9" of usable lock, but the lock itself is a few inches longer.

Is there a lovck lock on the cable to the bar?

I don't even bother with the cable because any bolt cutter will easily cut it.

Is it possible to use this to secure two bicycles?

With the 4ft cable that comes with it, no way. A ten foot would be required. It's best to have a ULock through each bike's front tire and frame, but if your neighborhood doesn't see a lot of bike theft, one lock and two cables will suffice.

Is there an ID card included with the keys that can be used to register on the Kryptonite website if they're misplaced and need to be replaced?

With the lock and key, it is possible to register online. However, you must register within ten days of making your purchase. I missed out because I didn't open my package and lock it right away because my bike is currently locked in a storage locker. A fee of ten dollars is required. 00 fee for a one-year registration with the option to extend it later.

Selected User Reviews For Kryptonite KryptoLok Series 2 Standard Heavy Duty Bicycle U Lock with 4ft Flex Bike Cable

The lock was cut in less than 7 seconds! It's a rip-off to promise $1500
3/5

I bought this lock because of the high Amazon reviews, but if you look past the stars and read each review, you may not feel as confident in purchasing this product. I assumed that a company willing to pay up to $1500 for your stolen bike must be a great product that has never seen a stolen bike, but it turns out that it's all a marketing ploy. You'd think twice about locking up your investment with this lock, as evidenced by all the pictures of people's stolen bikes/cut locks here. At a bart station inside the paid area, right under the camera, my lock was cut in less than seven seconds. Before attempting something like this, the man clearly knows how to cut it quick. He exited the train, walked up to the bike area, cut my lock, grabbed my electric scooter, and dashed back down to catch a train. He used battery-powered power tools that didn't require any plugging in. It was really that simple. I read the other reviews here, and it appears that many people share my misperception that this product provides security; it is a false sense of security. When it comes to their product, this company fails to deliver. They simply ignore you until you escalate via social media, at which point you will receive a call back stating the same thing. They refuse to acknowledge that their product was insufficient for the price at which it was made and sold, and they refuse to stand behind their $1500 guarantee, claiming that fine print made it impossible to claim. Be careful who you buy from.

Bolt Cutters beat a stolen bike in San Francisco
3/5

Last night, my gorgeous chromoly Specialized Allez was stolen, and it appears that this lock did little to deter the thief. Although I understand that no lock can deter a determined thief, conventional wisdom holds that cutting a U-turn requires the use of a power tool. lock. The fact that it appears to have been defeated with bolt cutters is particularly concerning in this case. The break was caused by shear force rather than abrasion caused by an angle grinder, as shown in the detailed image of the break. Any lock that can be easily broken with bolt cutters, in my opinion, should not be used in a medium to high-crime area. Advantages: br>br> br>Nice mounting mechanismbr>Should work in low-crime areasbr>Lightbr>br>Cons: br>Cons: br>Cons: br>Cons: br>Cons: br>Cons: br>Cons: br>Cons br>Bolt cutter losses.

Continue on to the next lock
3/5

My bike was just stolen from the bike cage at my apartment, and I have to agree with the others here. It was incredibly disappointing because I had both the rope and the u-turn. My bike was the only one stolen because it had a lock attached to it. br>br>I wish I had invested in one of the locks with the alarms and all. It was a waste of $1200. Thank you, Kryptonite.

Quality has vanished from what was once a fantastic product! RECOMMENDATIONS ARE NO LONGER ACCEPTABLE
3/5

I've had Kryptonite for a long time and have never hesitated to recommend it to others. So, what went wrong? It's something I'm still pondering. The internals of the locks, as well as the keys, have changed. The keys have a cheap feel to them and a cheap appearance to them. It's difficult to open the locks. Getting the key into the lock is frequently difficult. Aside from that, the lock's overall quality appears to be subpar. I made the mistake of handing over my old lock to someone who was in desperate need of it. I purchased a new Trek and, as is customary, my first purchase was a Kryptonite; I am SO SORRY that I threw away the old lock. This product's quality has vanished; yes, it's Made in China, but it definitely feels like a low-quality Chinese product.

I strongly advise you to buy either 1) a new lock or 2) a new combination lock
3/5

I'm hoping this item isn't a genuine kryptonite lock. After a little more than a year of use, the lock became extremely difficult to unlock; I had to patiently wiggle the key back and forth, hoping that it would somehow click into place and unlock. It has become permanently locked and will not unlock after putting up with it for far too long - I can even see how the internal mechanism has shifted to the point where it no longer lines up with the key. I'm now trying to figure out how to get it off my bike. br>br>I strongly advise buying either 1) a different lock altogether, or 2) a guaranteed Kryptonite product from an in-store retailer. the location of the shop.

It gives the impression of being safe
5/5

This lock was purchased just over a year ago and has performed admirably. This lock, in my opinion, cannot be beaten. It has a very safe feeling to it. br>br>However, there is one thing to keep in mind: The U Lock is a substantial piece of equipment. It comes with a bracket to mount to your bike so you don't have to carry it on your body or in your bag, but the lock is too large to mount anywhere on my bike without getting in the way of something (e. g. , a passenger). , my legs when pedaling, my rear rack, my water bottle cage), so I have to either carry it on my body or secure it to my rack in an unusual way so it doesn't hit my back tire. br>br>So, yes, you will get your money's worth if you buy this lock. Just be aware that you'll have to figure out how to transport it.

There was only one purpose for this product: to help people
3/5

It was a failure. Before they are sued, they should be taken off the market. All that phony nonsense about hardened steel and the like - it's all a load of nonsense. BSbr>br>This is all that remains of my bike, which I abandoned at the Berkeley Bart station. In a matter of seconds, someone slashed through it. It's a shame because I've had that bike for ten years and adore it. Only a few months ago, I purchased a new lock. It is no longer there. Hundreds of chopped Kryptonite bike locks littered the bike stand, which was quite interesting. It appears that thieves are looking for this brand because it is so easy to cut through - If anything, Kryptonite's design engineers and marketing team are pulling a fast one on us, and it's costing us a lot of money. You should be ashamed of yourself for releasing a product that fails to fulfill its sole purpose. This piece of garbage should be removed from the market.
