This is a good price lock. I only need a lock when I go to the gym, I may not believe this night in a rough hood, but occasionally use it great, the combination number wheel is big and easy to read. The chain is padded, so it's nice to wrap it around the jacking pipe or seat post of my road bike without having to worry about scratching too much. Overall, I will buy it again.

Ownership time: more than # uses in more than two years: I ride my bike to TX Medical Center in Houston every day and lock my bike out of one of the busiest public hospitals. Sometimes I leave my bike in a place where there is little safety monitoring, and a few times I leave it overnight. I am pleased to report that my bike has never been stolen or tampered with. It's a scary-looking lock, and I guess it's a deterrent to theft in itself. I like heavy chains surrounded by thick black sleeves that say "kryptonite". The heavy locking mechanism is well adjusted, so there is no doubt whether it is locked or unlocked. The extra key is good as a backup. I even registered my key so that if I lose one, I can order more in the future. I've used the lock over and over again and exposed it to extreme heat and humidity and torrential rain, but it still seems to work as it did when it was new. I did research before I bought the bike lock, which was the type and brand I decided; obviously I was satisfied with my decision. For maximum security, I recommend using two different types of locks, such as a chain lock (like this lock) and a solid lock. In this way, bicycle thieves will have to use two different tools to get your bike. That is to say, most of the time, I am not worried that my bike is only safe with this chain.

After our bike was stolen twice, I decided to lock it to prevent our bike from being stolen again. This lock is great! It's super strong, so I don't think there's a way anyone can cut / break it, it folds well, it's small, it has a bracket, I can attach it to my bike, and there are three sets of keys plus a copy code, which is great, because I have a tendency to lose something. I'm really happy with this product, it's totally worth the price if it prevents me from changing another bike!

My son absolutely loves this as a gift! Better than any lock we've ever bought before! The quality is much better! So powerful! Don't think his bike will be stolen again! Not this time, not this lock and chain!

This chain and lock are no joke. Heavy, almost screaming fuck! I bought it to protect my new motorcycle. I'm glad I wore this length instead of the three-foot short one.

My bike was locked on the bike rack of my truck, which was parked in the hotel for several nights. The lock prevents an attempt to steal a bike, as you can see in the picture. The thief could cut it neatly through one of the links, but it must have taken too long to stay and cut it again. They also tried to drill through the keyhole, but the drill bit broke. Thanks to this AKM lock, my bike is still there. Follow-up editor: I had to have the locksmith remove the u lock because it was badly damaged. He extinguished it in about 10 minutes-sparks splashed everywhere and the weather became so hot that he had to cool it with a glass of water several times. My mistake was to reverse the truck to a wooded area where the bike was locked in the bike seat behind the hotel parking lot and tried my best to hide it. The problem was that I gave cover to the thief and there was no doubt that his knife had sparks. The locksmith said it would actually be better to leave it outdoors-a spark like that would attract a lot of attention.

I tried to cut this with my 24 "bolt cutter. There's no chance. Made a little mark, that's all.

It's well locked, but there are some things you might want to know before or after the purchase. 1) Amazon lists the 5.25-foot lock / chain as 5.25 inches. 2) do not force the key, because it is not a sensitive key, but a link suitable for the chain, try to keep it (the last link) in a straight line (in the chain), but try not to push too hard, otherwise the key will not turn. 3) owning (5.25') is a good thing when there is nothing around you but a tree of the right size to lock a bike. 4) Krytonite rated the lock as 8 of the 10 security levels. 5) it can be wrapped well under my seat when riding a bike, but if I don't have a fender (to help keep it), I don't know where I'll put it on the bike because it's quite big.

These things are really great. First-Color option. I like to be able to provide a unique look and feel on almost anything, so one of my favorite things is color. I bought me a blue one and an orange one for my wife. Both colors are perfect. The lock itself looks safe, and it couldn't be easier to set up a combination. The cable is not the longest, but it is long enough that I need a bike, and because my wife and I ride anywhere together, if we need a longer cable that can hold two bicycles, we can connect them together. One of my favorite features is the bracket installed on the bike. There aren't many perfect places for it (I find it best to point back under the seat), but once you find the perfect position, it's easy to install the cable lock into the bracket and simply remove it when needed. It is better than having to wrap the lock around the handle or somewhere else. I always try to find at least one thing I want to see improved. To be honest, I haven't found the right one yet. Very satisfied.

I used it at the gate of the farm. A very heavy task. The hidden pepper spray was broken in as another door on the canvas cover. I hope this will stop stealing. I don't think I'll use it on my bike. It's too heavy to carry with me.
