It’s very heavy duty and secure.

The Kryptonite New York 1213 Cinch Ring Bike Chain Lock is a beast when it comes to security, but its weight might give you a workout even before you hit the pedals. Here's what you need to know:Pros:Unmatched Security: This lock means business. With its 12mm hardened steel chain links and the double deadbolt design of the lock cylinder, you can trust that your bike will stay put, even in high-theft areas.Cinch Ring Design: The cinch ring feature makes it easier to secure your bike without wrestling with the chain. It's a convenient addition that streamlines the locking process.Durable Build: Kryptonite is known for its robust construction, and this lock is no exception. It's built to withstand the elements and resist attacks from would-be thieves, giving you peace of mind wherever you park your bike.Cons:Heavyweight Champion: While the heft of this lock is a testament to its durability, it's also its Achilles' heel. Carrying it around can feel like lugging a small anchor, especially on longer rides or when combined with other gear.Overall, the Kryptonite New York 1213 Cinch Ring Bike Chain Lock is a solid choice for cyclists prioritizing security above all else. Just be prepared to feel the weight—literally—of its protective prowess.

This thing is awesome. I want to buy more and just lock everything up. Chain is beautiful and thick and strong. Locking mechanism is solid and satisfying to use.

Sehr gut,hat aber ganz schön Gewicht.

This lock is no joke due to its heavyweight. It can also be used as a piece of gym equipment for that reason, I only recommend that you get this if you have an electric bike or if you're a power lifter. Also, it does come with $5000 of theft coverage to replace your bike.

The size and security is good for my e-bike. I was looking for something lightweight that is not too heavy to carry. This is the ultimate security, the weight was too heavy for me to carry everyday so I decided to return it and purchased a light weight version of the chain lock.I recommend this one for people who are looking for securing their bike for longer period of time.

This lock feels rock solid, and provides a lot of peace of mind with an expensive bike. I live in a pretty safe place and so haven’t had anyone test this out, but it feels pretty bulletproof and I’d imagine that anyone looking to steal a bike would look elsewhere. The sliding loop is great - I can often lock up 3 bikes with the one chain. It is heavy as hell, though. But wear it around your shoulder or waist and you’ll feel like a real badass.

So good i bought the smaller one for local journeys as I live in cornwall

後輪はキタコのロックで地球に繋いでいますが、前輪の固定用として追加購入しました。

Cómo siempre llego en tiempo, hablando de la calidad puede decir que es una excelente opción de alto grado de seguridad, la cadena en si es larga lo cual es bueno para tener extra en caso de necesitar espacio, podría decir que puede asegurar dos bicicletas juntas, lo único que tienes que considerar es que es muy pesada, no es fácil de cargar, si eres un usuario que quiere moverse recomiendo busquen una más ligera

Good lock, good chain. I like the noose feature. It does get to be a bit of a hassle to thread the ring, but the only way around it would be to buy two locks which would obviously cost more and I'm not sure would be less hassle. I lived in a small apartment in a moderate crime area, outdoor bike storage was my only option. About a month after acquiring this lock and "noose" chain, someone attempted to defeat it to steal two bikes. I think they attempted to hacksaw through the chain which left narry a scratch. They did attempt the same on the lock shackle and succeeded in scratching off the black paint. Some (hammer?) blows to the lock only broke off the plastic barrel cover. Pick attempt resulted in breaking the tip of the screwdriver (which they left behind) off inside the barrel and ultimately failed. The system succeeded in securing my bike against this attack. Thumbs up, for that.HOWEVER, either due to the broken screwdriver tip jamming in the barrel mechanism, or damage to the mechanism itself, I was unable to fully insert the key and unlock it. I fiddled for quite some time with no success and finally called Kryptonite to explain the problem. The customer service rep was extremely helpful and promptly told me to cut off the lock and ship it back and they'd send me a new one. I used a wide (1/4", I think) cutting disc, but recommend the 1/8" ones if you need to do this as the wide one had to remove so much material it took a long time. Maybe eight to ten minutes per cut, and I did have to cut it twice to get the bike free. I sent the lock to Kryptonite and after just a couple weeks I received a new Evolution 4 Series Disc Lock, with carry holster and reminder cable. So, in short: great security for the price and 5-STAR customer service from Kryptonite, but I'm disappointed this type of lock cylinder can be damaged so easily. Given that this disc lock isn't really large enough to secure directly to the bike frame (with the exception of chain/seat stays), in the future I'll probably get a high security padlock to secure the chain to itself.There are better security chains, but they cost much, much more and will still fall to a grinder. After much research, here's my assessment: this noose chain from Kryptonite probably cost me about $50 bucks as part of the system and is very close to being impenetrable with hand tools. A strong person with quality four foot bolt cutters and something to pry against could cut it, but it wouldn't be easy. Stronger chains that are 100% impenetrable with hand tools are much heavier and cost four to six times the amount, but they could still be cut quite easily with power tools. So, I could pay half the value of my bike for a chain for slightly higher security, but in the event the chain gets cut and the bike stolen, insurance would cover the loss of the bike. I'm not sure insurance would cover the loss of the nearly-as-expensive-chain. Frankly, if a thief knew what was what, that expensive chain could actually be a target (i.e. cut the lock and steal the bike AND the chain). I decided that this Kryptonite chain is a "reasonable" degree of security that doesn't go overboard for my current needs.

This chain is smaller than the Fahgettaboudit, but it is still freakin huge. I use it to lock up my scooter and it looks downright intimidating. The lock is bright orange and the chain is a shiny gold, which should catch any potential thief's eye and hopefully make them consider another target.The noose design of this chain is great... since the chain doesn't have to meet in the middle, you have a lot more freedom when locking up. It isn't as much of a problem with a bicycle, but for a motorcycle or scooter you need every extra inch you can get.Please be aware that even this chain is NOT PERFECT PROTECTION. No lock or chain is cut-proof. It still helps a ton to keep your bike/scoot out of sight, and under a cover. That being said, this chain does give me peace of mind. I use it at home, where my scooter sits most of the time. Also keep in mind that the chain is HEAVY. I keep a different smaller chain with me when going to the store, etc. I have heard stories of scooters being stolen as someone heads into a grocery store for 5 minutes, but ANY chain should deter this. I mainly worry about mine being stolen at home, since that is where it sits 90% of the time and all throughout the night.
