This is an upgraded version of chain thickness and lock to what the lockpickinglawyer recommends. It is heavy duty and works very well

I had bought a Kryptonite Keeper 712 recently and liked it. However, the 7mm chain can be cut with bolt cutters. I wanted a more substantial deterrent. The Kryptonite 1275 seems like the maximum weight I was prepared to actually carry on a regular basis and the cinch idea was intriguing.Of note when I first opened the 1275 was how short 75cm felt compared to the 120cm of the Keeper. At first I was skeptical the 1275 was going to work. However after a few minutes of trying different combos I found the cinch design had every bit as much "useful" length as the 712. I settled on cinching around whatever pole or rack and putting the chain directly through the rear wheel with the Evolution 4 padlock on the lower frame. Seems to work well.The 1275 weighs 6.9 lbs (3128g) vs the 712 at 3.9 lbs (1766g). For that extra weight the 1275 is substantially stronger. Side by side there is no comparison. If a thief wants my bike they will need an angle grinder. Nothing is going to stop an angle grinder but bolt cutters and hammers would be pointless.Two slight cons to the 1275 - the padlock rattles easily compared to the 712 if wrapped around the seat post and secondly the protective fabric sleeve is slightly too short in my opinion. I carry the 1275 in a bag on the rear rack so it doesn't make any noise. Overall I'm happy with the 1275 and would buy it again.

I read through quite a few reviews of this product before buying it, and tried to go return the item today ONE DAY after the return window has closed, so now I'm stuck with a lock that won't open, and that is holding my e-bike hostage.A few weeks after buying it, I noticed the lock becoming harder and harder to unlock using the key, you'd have to twist and turn it 2-3 times before actually being able to release the lock. I had it in my notes to ask for a return, just to check today that it's no longer available for return and I literally cannot access to my e-bike as no matter what I do, the key will not unlock it, it's stuck, and of course it's like titanium or whatever strong metal so I'll probably have to call a lock smith to come cut it with a power tool..Do not go purchase this product.

Tough lock to deter thieves, a bit heavy to carry around, we put it in our rear rack bag, don't notice the weight on an EBike. We also use it to secure the bike to the rack and rack to the hitch. Already had one Ebike stolen due to only using cable locks, no more cable locks, only takes seconds to cut the cable with wire cable cutters. Also using Abus U lock and a Kryptonite LS U lock for added security.

It's a very good and sturdy lock the chain is thicker than I thought. The thing is that it's so heavy that I don't know if I'm going to carry it everywhere with me. I live in a condo and I have mi bike in a common bike room so I think I will use this lock to store my bike in the bike room and I'll get a lighter chain to carry it for the quick stops in the street. Like a kryptonite keeper.

A really secure lock which feels really solid. I use this one for securing two bikes together at home. The main downside is the weight but as this is used at home it's fine but I would use a less heavy one if I was out out and about.

La cadena y el candado se ven súper resistentes, definitivamente persuade a muchos, se siente de calidad y los acabados son buenos, la funda que trae no lastima tu bicicleta y en general es una muy buena cadena, no eh tenido ningún problema en éstos meses usándola. Sólo hay dos puntos importantes a resaltar que juegan en su contra, el peso y la longitud; es una cadena bastante pesada, pero te da la seguridad de encontrar tu bicicleta al regresar. El segundo punto es el largo de la cadena es algo corta y no te da mucho margen para atarla a diferentes objetos, ni siquiera es posible llevarla en la cintura o cómo bandolera. En general la recomiendo mucho si estás dispuesto a cargar con ella o si tienes la posibilidad de dejarla en un punto fijo.

I trust this lock as it would be very hard to break! I I use this lock to lock up my expensive e-bike, finding it easy to use.The ring on the chain is handy as it provides a longer length when you noose it around poles. (Put the chain through the ring on the end of the chain to noose it)This lock unlocks and locks easy. Note: I did find it sticky and hard to open after a month, but Kryptonite help me solve the issue I was having. The lock needed a little oil.How to oil your lock quoted from an email Kryptonite's sent me:"This is what we find works best to keep your lock in its best working condition lubricate the lock cylinder. You can also try using lubrication, such as Finish Line, in the key way to flush out any dirt or debris. Do NOT use WD-40, WD-40 is a solvent, not a lubricant and will, in fact, remove any type of lubricant that is in the cylinder. Use a lubricant that has a silicone, graphite or Teflon base only. Make sure the lock cylinder is facing up and spray or pour the lubricant into the cylinder. Let it sit for 5 minutes. Place a rag on your workstation and turn the lock over onto the rag for a minute or so. This should be done several times a year to keep your lock working properly." Thanks Kryptonite for the Pro Tip :)

This is an excellent lock. But if you're having trouble opening the lock and force the key, the key WILL break.Kryptonite will refund your locksmith bill AND replace your lock - that's why this review gets 5 stars instead of 4.Chain:Pros: Huge, but not too long. Heavy, but not too heavy. Intimidating enough that it will hopefully turn away any sorry sops with bolt cutters before they even try. Jacketed in a sturdy sleeve to avoid the pinchy-pinchy finger effect. Also, this chain is just downright attractive.Cons: Ok - so it's a little heavier then what's comfortable for a small or unfit person to move around, but if you bike a lot you've gotta be fit (haha not me), right? And it can be a little too short if you're stuck locking up to a thick pole or column.Lock:Pros: Good sturdy lock. Never had mine picked.Cons: If you don't listen to instructions and force the key, it WILL break, and it's INCREDIBLY hard to fish out, if not impossible - depends on how the key breaks. If the key resists, stick a screwdriver or something in the lock to re-align the tumblers and try again. Once more, DO NOT force the key! It will break!

Super massives Schloss. Die einfädelöse ist genial, warum ist da nicht schon vorher jemand drauf gekommen? Bis jetzt funktioniert der Schliessmechanismus bei mir sehr gut.ABER: Das Schloss wiegt eine halbe tonne und kann ohne Gepäckträger und schlecht tranportiert werden. Für meinen Geschmack ist es für jedes bessere Fahrrad was ja leicht sein soll ein Dilemma....aber das haben gute Schlösser wohl so an sich. Besser ne ordentliche Versicherung und ne kleinere Schloss variante. Für das Moped hingegen genau das Richtige.

This is as good as it gets for a barely portable chain lock. Unfortunately my copy had some issues with the lock cylinder but Amazon took care of it. This is VERY HEAVY and really should be used for permanent attachment (i.e. too heavy to cart around).

Premessa: l'oggetto nella foto, come anche il codice (3500308), corrispondono al vecchio modello di questo prodotto, in realtà il prodotto che arriva a casa è il nuovo modello (codice 999539), migliorato nella catena (forse anche nel lucchetto), che ora ha le maglie a sezione non più quadrata ma esagonale, quindi è più difficile da attaccare con strumenti da taglio.> Suggerisco allo staff di Amazon di aggiornare la foto e il codice modello.Comprato come antifurto per moto di grossa cilindrata.Ottima la catena e ottimo il lucchetto che può essere usato anche senza catena come blocca disco ed essendo rivestito in gomma plastica non rovina disco /sospensioni / cerchi.Il tutto trasmette sensazione di grande solidità, robustezza e sicurezza.La serratura ha tre chiavi ad alta sicurezza con codice, una delle quali fornita di led blu per illuminare la serratura di notte. Inoltre la serratura ha un piccolo sportellino per chiuderla e non far entrare sporco e umidità.L'anello a U del lucchetto si estrae completamente e ha un ottimo incastro, ben lubrificato, come anche la serratura in cui la chiave gira bene senza intoppi e non può essere estratta a lucchetto aperto.Il sistema della catena con l'anello a cappio scorsoio consente di legarsi a un supporto fisso (palo, cancello, etc.) pur contenendo la lunghezza della catena lunga a soli 75 cm, quindi con poco ingombro e poco peso, infatti l'intero sistema catena + lucchetto pesato sulla bilancia segna 3,1 kg.Unico neo: il rimborso assicurativo regalato da Kryptonite per il primo anno in caso di furto del veicolo è riconosciuto solo in UK (1.300 £) e Germania (1.000 €).
