Kryptonite Evolution 11-14mm U-Lock for Maximum Security with FlexFrame-U Bracket

Warp_Speed: Been using an Evolution mini 5 for about 10 years or so... it's a bit heavy for my travels but its still intact....
Saw this lock and just had to get it is very light weight and bit longer and narrower than my other lock...but still fits in many places to lock up around the city for quick stops.....has improved features that i like very much.....would recommend...

Aaron: Das ist bereits mein zweites Fahrradschloss von Kryptonite. Ein zweites musste her, da das erste - ein Kettenschloss von Kryptonite - zu klobig für das tägliche Herumgetrage ist. Dieses hier kann ich bequem am Zugband meiner Bauchtasche an der Hüfte tragen bzw. hängen lassen, ohne dass es am Fahrrad befestigt oder in einer separaten Tasche verstaut werden muss. Das Schloss wiegt absolut nicht viel und ist laut Kryptonite dennoch eins der stabileren Bügelschlösser aus deren Sortiment. So mancher Käufer hier beschwerte sich über die Schwergängigkeit beim Einführen bzw. Entfernen des Schlüssels - ich kann das nicht bestätigen. Natürlich flutscht der Schlüssel nicht wie eine heiße Messerspitze durch ein Stück Butter aber mit etwas Feingefühlt geht das easy peasy. Wer das Vorderrad gern mit anschließen möchte, kann sich das kurze Drahtseil dazuholen und es so mit absichern. Durch die etwas kleinere Ausführung passt der Bügel nicht um alle Objekte wie die Stange eines Straßenschilds aber mit etwas Kreativität findet man schon ein geeignetes Örtchen zum Anschließen. Ach ja, die kleine Taschenlampe am Schlüssel habe ich noch nie benutzt, wenn ich...

displayname: It's on the heavy side but that's expected.

olivier: Sa petite taille me parait être un excellent argument pour ne pas se priver de l’emporter. Donne un sentiment sécurité. Satisfait de mon choix.

Rivet Man: This is a good lightweight U-Lock. It's not perfect, but it's pretty good. A few notes.
- The "LITE" label seems very silly. Why advertise that it's lightweight. Luckily this came off instantly with a tiny bit of acetone / nail polish remover.
- This is on the small side of U-locks. I've found that I can generally lock to most things by going around my rim and tire through the rear triangle and to a solid object (Sheldon Brown's method) with my large 55mm wide tires, but on some objects it's a bit awkward. If I just go around my steel frame tube, then I can lock to many things easier.
- My wide tires (55mm wide) press the two legs of the "U" apart when I put it over the tire and it is difficult to install the crossbar. Once I figured this out, it is not a big deal and I can gently squeeze the legs back together with my hand to install the crossbar. But it was very frustrating before I figured this out and I just couldn't get the crossbar on.

gumgl: I bought this for its light weight and in this department it does not disapprove. I wish it came with a frame mount like the others, but its lightness makes it possible to just clip it around the frame or handlebars. One issue I run into all the time is the key getting stuck. I'm not sure why it keeps happening but it's really annoying to spend upwards of 1 minute trying to lock it when it should take 5s. And it happens with remarkable frequency. There's definite a design flaw to be looked at here.
As far as size, I am almost never able to put my bike *in* the racks. I always have to put my bike on the outside and line my frame up right next to a tube I can attach to. So far this hasn't been an issue.

Cliente Amazon: Ho uno Xiaomi essential e questo lucchetto ci si abbina perfettamente. È il giusto compromesso tra peso e robustezza. L’unico neo è doverlo portare dentro lo zaino non avendo un suo supporto da installare. Viene fornito con tre chiavi di cui una con led utilissima per quando si deve sbloccare il mezzo al buio. La serratura ha un meccanismo a disco secondo me molto sicura. (Per poterla scassinare necessità di strumenti particolari difficili da reperire) tutto sommato davvero contento dell’acquisto per quello che l’ho pagato!

André: El candado está muy bien, no es grande pero lo suficiente para anclar cualquier señal de la calle. Lo mejor es que es más ligero que la mayoría y eso es muy importante. Lo compré de segunda mano, está como nuevo y a mitad de precio.

Adam: The lock really is small - be aware before buying. I regularly have issues with trying to make it hug both my bike frame and the bike rack/pole etc, but the fact that I can pocket it anytime, weights 1.5 lbs and is still Gold Secure compensates for the extra effort. Eventually I always manage to find a position to make it work; I use it together with a Kryptonite cord for the helmet, bike bag or something else, and attached the lock to my bike’s frame with velcro to prevent rattling.

sk8prim8: I have 4 bikes. my evolution 5 was my carry on for everything. now i use this one for on the go. I don't use it over night. just for bars and running into stores. All in all it is good so far. I bought a used one for cheaper and it is fine like wine. A little lighter than my evolution five. does not fit as well with the dimensions like the five but just have to adjust or find another place to lock. I live in NYC.
