Kryptonite Evolution Long Shackle Bike U-Lock, Anti-Theft Security, 14mm Steel Shackle with Mounting Bracket and Keys, High Security for Bicycles Scooters,Black

No bike lock will stop a determined and well-equipped thief. That said, this one's more likely to cause them to pick on somebody else - if they aren't the sort who destroys what they cannot steal. I get a good-quality lock because I want to have a chance to ride home, not because I have an expensive bike, and in my experience, this is a good-quality lock. Also, from personal experience, use the lock at home, too, We lost a treasured hand-assembled hybrid to a B&E jerk who was after electronics - and rode off on an irreplaceable custom that I'm sure got torn up.

Kryptonite is an industry standard for a reason. These locks are easy to use, and while heavy and a little bulky, give a good feeling of security. The longer shackle model of the lock can be a little bit harder to store on a bike however, especially if you use bottle cages. The mounting system for storage has been upgraded from previous lock models. Previous Kryptonite locks I have used included a plastic clip that was hard to attach and detach from the lock without breaking, not to mention a nightmare to install on the bike. With the new mounting kit, the plastic components are a little bit larger, but much more robust. The release mechanism feels less likely to snap, and the installation of the kit includes the use of a webbed strap and metal buckle (the bike is protected by a rubber insert) that firmly attach to the bike frame. Be cautious, however, that bike frames with non-round frame members can be a little hard to attach to.

Well worth the money!! U won't regret it but$$it

This is a sturdy lock, somewhat cheaper than the "forgetaboutit" New Yorker, and there is a reason, but you need to see the "lockpickinglawyer" on youtube for the explanation. But it does come with a 1 year insurance policy, which requires you send them the broken lock and your bike needs an appraisal. This is an AWESOME lock. If you haven't used a u-lock, this is the one you want to give a try. The lock is hard to unlock, but use it a few times you will get it.

Way able to use this to lock two bike together on a bike rack and have peace of mind. It is frustrating to have to carry an extra key, but overall not a big deal.

Heavy, but does the job. I use 2 locks to make things more difficult for thieves.

Quality as expected from Kryptonite. Very pleased with this lock.

I've had this lock about a year and use it on a cargo bike. It seems very solid and the mounting bracket has worked well. The big problem is that it is difficult to get the key to lock or unlock. You really have to fiddle with it and it has gotten worse over time. I'm concerned that I may get stuck somewhere not being able to unlock the bike. So I have now decided to replace this lock with another brand.

I cannot foresee anyone finding it worth their time to get through one of these to get my bike. The guidance is to buy a lock that costs 10% of your bike however I would disagree with that. A good D lock ensures you will come back and find your bike where you left whereas with a cable lock no matter what bike the thief can steal your bike and make it worth their time. This lock comes with 3 keys one with a light on it. everything is sturdy and several months after the original purchase the lock still works great.

Nach einem kuriosen Youtube-Video der jährlichen, polnischen Fahrraddiebemeisterschaften ist mir der Markenname Kryptonite schnell zum Synonym für qualitativ hochwertige Ware geworden. In der Tat: Ich habe für unsere zwei neuen Räder noch für den Liefertag schnell per Prime zwei dieser Schlösser bestellt, die seither täglich im Einsatz sind. Wir kombinieren sie mit dem gleichfarbigen Schlaufenkabel Kryptoflex, um Vorderrad, Hinterrad und Sattel sicher zu befestigen. Und um die Farbe geht es auch. Kryptonite bietet verschiedene Sicherheitsstufen, Gelb für die ganz großen Großstädte, Orange für Großstädte und wer weiß welche noch für kleinere Orte. Orange muss es schon sein. Überhaupt ist die Ausführung voll gummiert, und beschädigt den Rahmen daher kaum. Dann ist da noch der Befestigungsmechanismus, der zwar auch leicht zu befestigen, aber leider bei Kopfsteinpflaster leicht aus der Position kommt. Bei dem Damenrad war überhaupt kein Platz dafür am Rahmen. So habe ich die Aluminium-Halterung auch vom Schloss abgezogen und hänge es seither entweder an den Lenker, oder packe das Schloss zusammen mit dem Schlaufenkabel in die ebenfalls neu erworbenen Ortlieb-Seitentaschen. Nichts klappert mehr umher, da stört auch das Gewicht keinen Menschen. Das Metall ist wunderbar stark, die Schlösser sind sehr gut, nach zwei Monaten war allerdings ein bisschen Fettung nötig um den leichten Rost am Stahl zu entfernen. Es gibt eine kleine Klappe um Wassereintritt in das Schloss zu verhindern. Die Farbe schreckt ebenso ab wie das Schloss selbst, man muss aber eben auch immer sorgfältig den Rahmen mit einem unbeweglichen Metallgegenstand verbinden. Für jedes Rad zu empfehlen!

Excelente la medida perfecta y calidad superior, la dejo 2 horas en un centro comercial donde hay bandas que roban a diario y me da la tranquilidad y seguridad q necesito.....

Muy buena calidad, aunque el peso del producto también es notable. El soporte para sujetarlo a la bici es de calidad media (porque se sujeta con una cuerda de nylon), aunque gracias a que utiliza esta cuerda de nylon, es uno de los pocos soportes para candados que me permiten colocarlo en una barra no cilíndrica (cuadros ovalados o curvos) Llevo dos semanas con el y todavía no me han robado la bici, lo cual es un logro porque está entre seis y ocho horas atada en un barrio y un lugar donde las estadísticas de robo de bicicletas son altísimas (a mi ya me robaron una anterior con la que usaba un candado de peor calidad y no dejaron ni el candado), también combino este candado junto con un ABUS Granit-54 x-Plus, para hacerla totalmente inrobable, salvo si cortan el cuadro de la bici con una radial o la valla a la que sujeto la bici...

Semble robuste. Idéal pour sécuriser 1, voire 2 vélo(s) à assistance électrique.
