Kryptonite Evolution series 4 Standard vs. New UWondering what the difference is between the Standard vs. New U? I was so I searched on the Internet and Kryptonite's site and found almost no difference other than the New U is 4 oz lighter. From the Kryptonite site here are the descriptions of their deadbolts:Description for Standard: "Hardened DOUBLE DEADBOLT DESIGN gives additional protection against twist attacks"New U: "Patent-pending HARDENED DOUBLE DEADBOLT design gives additional protection against twist attacks"So one is patent pending and the other isn't? Or did they just apply for the patent later and forget to update the description for the Standard?Well now that I've received my Standard, I would say the New U gives more protection from twist attacks. That is, after sawing once through the U, how easily can a thief twist the cut U out of the way and steal the bike? Watch the video on the New U and observe the flattened ends of the U which should provide additional resistance to twisting. The Standard has a U with round ends (see attached photo); only the part that contacts the deadbolt will resist twisting. How much extra protection will the New U provide vs. the Standard? I don't know. Kryptonite rates both as security level 8. But I wish I had known of this difference before I bought one. Kryptonite should do a better job explaining the difference. Instead of both descriptions saying "additional protection against twist attacks," maybe they should delete the word "additional" from the Standard description.And be careful of price when you're buying: the New U price fluctuates between $82 (almost as much as the higher security, and higher weight, New York New U) and $68, and the Standard has varied between $66 and $40, all in the last 6 months on Amazon. So the price difference between the two models can be negligible, or quite substantial.Overall though the Evolution Standard seems like a very good lock -- replacing my ancient (~1990) Kryptonite-4 which has an easily pick-able cylindrical key!

L'antivol est de bonne qualité. Lourd, semble solide et facile d'utilisation. Il est vrai que la serrure accroche parfois un peu mais avec un entretien régulier approprié (avec un lubrifiant spécialement formulé pour les serrures), aucun problème à déplorer, malgré une utilisation en plein hiver.Nos deux vélos sont équipés chacun d'un antivol de cadre et de ce modèle d'antivol U Kryptonite. Ils sont ainsi sécurisés par l'antivol de cadre bloquant la roue arrière et cet antivol U qui assure le cadre et la roue avant à un point fixe de qualité. Jamais eu de problème en plus d'un an d'utilisation quasi-quotidienne. Alors, est-ce nos vélos qui n'attirent pas suffisamment les convoitises, ou l'antivol qui freine les voleurs ? Toujours étant que nos deux vélos sont toujours en notre possession. Je recommande vivement ce produit.

Habe das Schloss nun seit ca. 1,5 Monaten täglich in Betrieb und bin mit meiner Wahl zufrieden.Es vermittelt definitiv ein Gefühl von Sicherheit, der Bügel und Querbalken wirken sehr massiv. Das Schloss wird mit 3 Schlüsseln geliefert, 2 schmäleren und einem größeren mit eingebautem Licht (wer braucht sowas?). Das Metall am Schlüssel wirkt auch recht zuverlässig, kann mir nicht vorstellen dass der so leicht abreißt.Die Rahmen-Halterung finde ich persönlich auch OK, leicht zu montieren und mit sicherem Sitz. Die anderen Meldungen zum klappern des Schlosses in der Halterung kann ich bestätigen, allerdings empfinde ich das Geräusch als überhaupt nicht laut oder störend beim fahren.Größter Nachteil; das Schloss ist wirklich schwer!Bin dennoch sehr zufrieden und würde es auf jeden Fall weiterempfehlen.Nachtrag Oktober 2020; das Schloss leistet mir immer noch gute Dienste. Manchmal friert es im Winter ein, wenn man vergisst die kleine Abdeckkappe vom Schlüsselloch zuzuschieben, ansonsten gibt's weiterhin wenig zu bemängeln.

Got two sets of them Mini-7 and Series 4. Both are brilliant nothing else to say, locking device is working very well. Somebody already tried to cut the lock!! It only has bin week. But guess what, they litterally only scratch the surface of it, probably after trying for a bit they realised that it's not the lock to cut!!Couple of thing to point out1. Small bracket which you can attach to your bike and then just hang the lock on is very cool, plastic but lightweight and sturdy enough.. at least you dont have to hang the lock in the odd places while cycling!2. There was a 3 key set and one of them came in with the light on the key, this is small but very cool feature, actually does help to open up the lock in the dark.!It's quite heavy thou, but this is the only way to protect your bike in town.... You can easily remove it and store it when cycling out!

Mi è arrivato lucchetto, 3 chiavi di cui 1 con luce led, fascia per attacco alla bici, manuale di istruzioni e promozione per gli inglesi :(.In ogni caso mi pare solido, si attacca bene alla bicicletta e come l'ho messo io non da fastidio.Pesa un po' quindi non è per velocisti :)Molto comoda la chiusura della serratura.Si attacca anche a pali medi (passa al pelo).Sono molto contento ovviamente saprò se resiste in caso di tentativo di furto O.oAllego foto per far capire le dimensione su una bicicletta normale.

Impressive looking lock that does not weigh as much as other locks, but still provides excellent security for my bicycle. I use this to lock up my Bianchi Volpe and can sometimes also lock up another bike next to mine. I am not a fan of the small metal fitting that is supposed to be used with a plastic fitting to hold the lock on your bike, so I taped the metal to keep it from scratching my paint finish. I use this lock with multiple bikes, so I don't want to buy plastic fittings for each bike so taping it makes sense. The keyway is in the center of the orange part and the key goes deep into the crossmember. The keyway has a handy plastic cover to keep the keyway clean and it works well and does not get in the way. And one of the keys has a built in flashlight with just enough juice to help you unlock the lock. I feel very confident when I use this lock. Note that it has the flat key, not the old round one that could be picked easily. This lock will not survive an angle-grinder, but then again, nothing will survive such an attack. I use this lock as my primary way to prevent theft and I add an Abus frame lock with a hardened steel chain, figuring that few crooks have experience with a frame lock in the US, so if an angle grinder is used, it will cut through the Kryptonite and the Abus chain, but the frame lock would take multiple cuts, plus a lot of fussing, to defeat the frame lock which is around the rear wheel. Plus, all of this looks impressive and hopefully a thief will bypass my bike as being too much work. Note that many people use a cable lock to tie up the front wheel to the U-lock, but I prefer a hardened steel chain as a pair of pliers will not cut through the U-lock nor the chain.

The new centered key mechanism and double-bolt design is really excellent and big improvement over the previous designs that Kryptonite used to use. The key is more complicated, the keyhole is small and has a built-in cover. The key turns very smoothly on mine. The double bolt is a great feature because the key controls bolts on *both* sides of the lock requiring a thief to cut both sides of the lock before releasing the bike. This is a substantial lock.That also means that it is *heavy*, so it may not work great if you are looking for a lock to carry around everywhere. I use this to lock up my commuter bike outside overnight, and the lock gets left on the post 24 hours a day. So far has worked out. Crossing my fingers.The common wisdom is that it is better to use as small a lock as possible to reduce the possibility of using a crowbar to get leverage on the lock. But sometimes you need a big lock, and that's when I use this guy. It works well on my hybrid to thread it through both seat stays, the wheel rim, and a sizable post. This leaves very little space and there is *always* a less securely locked bike close at hand. All locks can be broken, so the game is to lock it up enough so that most thieves would rather spend their time on other bikes (or, hopefully, doing something productive for society).It's true that the mounting bracket is a bit of nonsense. It doesn't work anywhere on my bike, so when I do carry this lock around, it has to go in a bag.

Very nice lock and it looks as though it would be VERY DIFFICULT if not IMMPOSSIBLE to get around WITHOUT making a REALLY BIG JOB out of it...my ONLY gripe with it is its BIG and TOO heavy to be traveled with on a bicycle...my bike is a nice light G.H.P. 24" BMX Pro Race and I will use this lock at home on my covered porch with a tarp over the bike and a good cable lock keeping it tethered to a post, so its worth having just not travel friendly for people like me that care about the weight of their equipment. The lock feels like it weighs at LEAST 10 lbs. (and my whole bike only weighs 22 lbs. LOL)
