Kryptonite Evolution Series-4 LS Heavy Duty Bicycle U Lock Bike Lock with Transit FlexFrame Bracket (4-Inch x 11.5-Inch)

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.

WOW this specific model of kryptonite evolution series 4 LS is amazing. the reason i went with this specific model is first its rated 8/10 for toughness to steal and second the LS version is long shackle. which really helps me with my mountain bike reason being i dont have to take off the front tire the shackle is long enough to fit through my tire frame and bike rack. now this doesnt fit on my bike with the bracket provided with the lock this is due to the fact that the lock slides onto the bracket and if the bracket was placed farther up there isnt enough room in my bike frame. the lock does fit in my frame if i was to bungie cord it or find a different way to secure the lock. i dont mind this at all and was expecting it do to the size of the shackle. i have another kryptonite ulock coming for just the back tire to the frame i would rather carry a extra lock then take my tire off every time plus two locks are better then one. also if kryptonite made it so the silver mounting bracket could slide up and down that would solve the problem of the bike bracket.

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.

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

I don’t know why they made this way, you turn it in 360° sometimes it’s hard locking!

Very sturdy bike lock. Easy to use. Would deter bike thieves.

This was a lot larger than I had thought. I was able to use it to lock up two bikes at the same time. I didn't think twice about leaving the bikes out of site. This lock is too large to mount permanently to my bike but I carried it in a back pack and that worked well.

With a supplementary 6-foot cable, this is the best lock set you'll ever own. At first it seems weighty, and it is heavier than any lock I've ever had, but once you've used it for a while, it's actually more convenient than other solutions because it's simple to attach and no combination to remember. Thieves won't even think about stealing a bike with this lock set. Well worth the money.

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.

Es bastante largo como para asegurar la bici a objetos lo suficientemente grandes o asegurar 2 bicicletas, tiene un aspecto robusto y de buena calidad.

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!

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...

acheté après avoir lu un comparatif. Cela fait plusieurs années que je l'ai et il est vraiment très solide et endurant. Il n'a pas bougé et je n'ai jamais eu de tentative de vol. bien moins cher que son principal concurrent et de meilleure qualité.
