Features and Specifications:

Its 12mm links are made from manganese hardened steel. Those are shaped into six-sided rings for additional toughness. This is precisely what makes bolt cutters hard to get inside the chains. Plus, the super hard material adds to the cropping resistance.

The Kryptonite New York U-Lock is also quite resistant to chisels and saws. It’s the double-skinned steel cover that’s protecting the locking mechanism. This prevents hammer damages as well. Someone could use a hammer to break it, but that would take hours, and you’d notice them before they could finish.

Should a thief use a power tool, it would take too much time and quite some effort. For this reason, it’s unlikely they would even want to try something like that.

It’s quite a heavy chain being about 5.5kg (12lb.), so it’s not the best portable lock. However, if you want some additional security at home, this chain will provide that. Plus, this chain is great to lock your bike when carrying it in a car.


It would be somewhat annoying to carry such a heavy chain with you at all times. So, it’s best if you leave it in one place. If you have to lock your bike somewhere in town, you can bring it in your bag. It’s just that you don’t want to do that quite so often.

Thanks to the protective cover on the chain, you can wrap the lock around your seat post, for example. This can make transport a bit easier. However, the cover might not be able to protect the paint of your bike.

The lock features a sliding dustcover that extends the life of cylinder by protecting it from dust, rain and other such factors.You also get three stainless steel keys in the box. One of the keys is lightened with a high-intensity bulb and come with a replaceable battery.

The chain lock isn’t quite as affordable as many other locks on the market. However, since it’s meant for high-risk areas and situations, it’s worth the money. If you own an expensive bike, this lock is a small price to pay to keep it always safe and secure.

The lock also comes with a bike replacement guarantee, an added business and further shows how much confidence Kryptonite has in the U-Lock.

The chain is 3-feet long. For some people, it may seem a little short if you want to lock in one wheel and the frame. There is a longer version available that’s 5-foot long if that works better for you.

It really depends on where you’re going to lock the bike. Do you think you’ll ever want to secure two bikes? The longer one costs more money, but it’s still cheaper than having to buy two individual locks. Think carefully about which size would be the best for you, but if worse comes to worse you can always buy a new lock.

Since the chain is as big, you might struggle with getting it through your wheel and frame. Though once you get a hold of that, it will be no issue at all.

It’s best you use it at home to add some extra security to your bike. You can also use it to mount your bike to the roof of your car. Because it’s so heavy, it’s not quite so easy to transport. You can mount it to your bike or carry it in your bag, but its weight would eventually become too much to carry every day. Regardless, you’re in good hands with Kryptonite.
