Kryptonite New York 1210 12mm Chain & Evolution 14mm Disc Lock Set: Maximum Security for Your Bicycle

David Antonio Silva Torres: El candado cumple su funcion sin ningun problema, es super robusto y muchisimo mas practico en comparacion con mi otro candado en forma de "U". El unico problema es que es muy pesado, pero bueno todo sea por la seguridad.

jxs: You are definitely not going to be carrying this sucker around with you on a bike, it is a heavy beast. I use it at home to lock my ebike up. The chain cover helps alot with threading it through the frame and wheel without damaging the bike.

Rob I: So this lock is a beast, but needed to go to a chain lock for an e-bike as the typical 4" U-lock was not wide enough to go through the rear tire and seat tube...they would work if you just want to frame lock. Although anyone with a grinder can cut through just about any lock out there this NY 1210 is beefy enough and the extra thick links are shaped to help slow the cutting process. Thinking it is more than enough to secure the e-bike and if not, Krytonite offers insurance for theft if the lock fails. Yes, you will need to probably carry this bad boy in a backpack which was my plan from the start. If you want to save some weight look at the Krypton Evo 1090, which I use on a different bike and like as well.

Dan M.: With this chain and lock, I am confident that my bike will not get stolen. It is heavy, so I wouldn’t take it mountain biking or on long trips. However, it is great for short errands. It’s too big for my small bike bags, so for a quick errand around town, I don’t mind taking it in my backpack. The peace of mind after parking my bike makes it worth it.

But the best and by far the most important use for me for this chain/lock is to secure my bike at home when I am away on a long trip. If a thief knows you’re not home, he may take more aggressive measures to try and steal the bike than he would if it were outside and in the open for any potential bystanders to witness. But when he sees this heavy duty chain and lock wrapped around a beam that holds up the garage ceiling - which is the floor of a large loft above that is loaded with heavy items - he would most likely conclude that it is not worth taking the risk to try and steal this bike. It would just take too much time, as well as noise, to try and cut this heavy duty lock/chain; and it would be extremely risky to try and cut the support beam that holds up the garage loft.

This striking,...

Sebastian J. Delarosa: The weight of the chain is no joke but it does get easier over time. This is my second time buying this lock ONLY because I left the chain locked at a construction site (for 2 days, a dumb move) while I took my bike elsewhere and they cut through it with something that looked like a torch, after cutters didn't work. Clearly only heavy duty tools that no casual thieves carry, will be able to defeat this lock. For 5 years, this has withstood secluded areas without cameras, high theft areas, and all manner of spontaneous grabby scumbags. As of 11/6/2020, a passerby grabbed my bike off my patio at 2am, without seeing the chain locked to the saddle. He didn't make it 3 feet trying to ride it, the chain tangled in the pedals, so he tossed the bike and I lost him as he ran away on foot. Not even locked to an anchor, THIS LOCK WORKS.

White77: Catena e lucchetto possono far desistere anche un ladro esperto, massiccio e robusto. Spedizione e venditore ok

Amazon Customer: Feels really secure.
Use it to lock up my Suzuki Bandit every day at work. Several bikes have been tampered with but no one has touched mine as this lock looks impossible to break into. Could be classed as a visual deterrent...
It also drove my insurance costs down by more than the cost of the lock for 1 year.
I will probably end up buying another to leave at work as it’s really heavy...

WrathfulDeath: If you use this lock, you can rest easy and your bike will be difficult to steal (if you lock it up correctly). The chain length is just enough to wrap around the back wheel and frame to a bike rack or pole (for my bike anyways). The chain is quite heavy and I would like to see a thief try and hack through it or the lock. The length of the chain from end to end is 39" but the inner circumference is more like 34" or 35". For me this is perfect to wear around my waist as the weight of this doesn't bother me at all.
The only gripe that I have with this is the key, specifically the key with a the light. It is bulky and doesn't fit on my key ring so well. Thankfully there are 2 smaller keys supplied so I don't have to use it. On a side note, the light on the key isn't the best build quality. You really have to press down into the button to light it up and sometimes it doesn't work.
For anyone buying this, I would recommend also getting a large carabiner. I use one to hold the chain together as I unlock the padlock from my bike (I keep it locked around my handlebars while I ride).
