Un candado excelente. Viene con cinco llaves, incluida una con luz.

Es muy fuerte, algo pesado y aunque incluye una abrazadera para llevarlo en el cuadro de la bicicleta yo no lo monté porque me resultó un poco incómodo. Buena opción para complementar con otro candado de mejor o menor gama.

El candado es de muy alta seguridad ahora bien, viene justo de engrase y más vale que lo aceites de vez en cuando porque después de unas lluvias puedes verte con una bici que no puedes desencadenar, y este no lo cortas con ninguna cizalla. Repetiré

Debido a que la parte donde ingresa la llave es de plástico da una sensación de debilidad. Ojalá que no lo vea forzado, creo que lo usaré con una cadena adicional

Extremadamente firme. Sólido. Se me Ocurre hasta para defenderme de alguna eventualidad. La única pega, es que el tubo transversal del cuadro no me permite poner el porta candado al ser mucho más grueso por se runa bicicleta eléctrica.

Las primeras impresiones son de un candado de gran calidad. Es pesado, pero es un sacrificio mínimo para mantener tu bicicleta segura. Terminamos comprando un candado igual para la bicicleta de mi novia. 10/10

Este candado U-Lock es la mejor opcion de un nivel de seguridad 8/10, y al mejor precio que encontraran en plataformas digitales.En definitiva es una de las mejores 3 marcas en candados U-Lock, quiza no es de calidad excelsa como lo es Kryptonite o Abus, pero la funcion de seguridad es muy buena y bastante confiable.Apesar que algunos de los materiales se ven que duraran menos tiempo, un buen cuidado podria extender la vida util al igual que las marcas previas que son de mejor gama.Adicional, les sugiero que la inversión del candado ronde entre 30-50% del valor de su bicicleta, en mi caso no quise invertir mas en uno de calidad superior o nivel 10/10 ya que el candado superaría mas del 50% de costo sobre el valor de mi bicicleta.Siempre se recomienda combinar el uso de este candado con algun otro U-Lock, Cadena o Cable de Acero de menor calidad (nivel de seguridad 2-4/10).(Si es cadena que al menos sea de 1/2 de pulgada de grosor, y con un candado de al menos 50mm y llave de alta seguridad.)

Es un candado grande, permite asegurar la llanta y el cuadro de la bicicleta en muchísimos lugares. Me he animado a ir a más partes y dejar mi bici asegurada en lugares en los que no la dejaría con otros candados.

C'est de lourd ! Quand on les dispose sur le guidon, ils ne passent pas inaperçus.La serrure semble ne jamais faillir, le plastique entourant le bloc serrure est fragile : il casse en cas de chute à hauteur de vélo sur sol dur ; le fonctionnement n'en est pas entravé, c'est juste moins esthétique.Sa bonne note délivrée par les organismes de test m'a convaincu de l'acheter.

Overall I'm very happy with it, especially for the dual bar lock system. I did extensive research on locks and came to the conclusion that this is the most secure for its security grade, and for the price point. Even more than other higher security grade well-known name ones. The only thing I don't like is the plastic shell on the lock itself, it feels and looks flimsy. But no problems so far. The lock system is very smooth and easy to use, I like how slim the key is, and love the auto-shut cover on the keyhole to protect it from water or dust. The carrying saddle for the lock is easy to use as well, however, would be better if not plastic. The U bar is wide enough to fit both my front wheel and the frame, even through one of the paddles onto any thick bar/bike lock, this method adds extra annoyance and could deter thieves ( recommanded by police). Bike thieves suck, good luck folks

Ligeramente pesado, pero vale la pena por la seguridad de tu inversión,fácil de llevar y/o empotrar en la bicicleta con su bracket incluido... en mi opinión esta mejor su estructura que el similar de la competencia,(Lo que debilita a supermán) jejej..Se ve más seguro y el cable “akita” está mejorQue el de la competencia.. simplemente es de 10mm X 7 pies y además trae 5 llaves y una es con lámpara incluida a mucho mejor precio

I've had this lock since summer 2016 though to be fair I've got two bikes of different values so I use 4 different locks. Two including this lock and an Abus lock on my more expensive bike when I'm out, a different Onguard scooter lock with my more expensive bike in my shed and a fourth lock, MasterLock, for my cheaper station bike.This lock is clearly marked as Sold Secure Gold on the actual lock. The lock is smooth and well made. If the lock your receive doesn't fit both of these criteria then it is not an original. I should add none of the bike locks I have from different manufacturers feel rough from new.Like all the bike locks I have from Onguard, Abus and Masterlock it is is impossible to lock this lock up without using the key. One of the keys you receive in the bundle should have a light on it but to be honest I use one of my front bike lights when locking/unlocking it and the other lock I use if it is dark, so I can't tell you how useful it is.Unlike the other posters I've been lucky and not have had problems with the barrel getting stiff after months of use.This is probably due to the fact that the bike I use this lock on tends not to be left outside unattended for more than a few hours. Therefore I rightly cannot say what the durability of this lock is if left to the British elements for months.The main issues with the lock are:1. That while it is a large D-lock it only works on standard bike racks. If you are locking the bike properly - by which I mean through the frame and back wheel* - to a lamp post or non-standard bike rack the lock will not fit. In my case as I use a Abus cable lock as well so I can always lock both my wheels and frame up. (I do have a cable to lock my saddle but actually haven't used it.)2. The lock is heavy. I actually carry the lock in my rucksack and I can feel the weight difference with it in and out. Due to being female and the bike I use it on not having a horizontal cross bar, there is no way for me to fit it to the frame if I want a water bottle. I suppose I could bungee cord it to the pannier rack to carry it on my bike but I really can't be bothered. Either way I've not used the flimsy looking bits of plastic that come with the lock to attach it to the frame.I should add if you have quick release wheels and are locking it to a standard bike rack, then the lock is big enough for you to take the front wheel off, put it against the back wheel and lock both wheels plus the frame filling the entire lock. I don't tend to this as it is a hassle.Does this lock work? The only time someone has attempted to steal my bike I hadn't secured my front wheel with the Abus chain lock and so they undid my front wheel. Oddly they didn't steal it so either someone disturbed them, or they realise that nicking the wheel without the bike was pointless and this lock worked as a deterrent.In regards to bike thieves - if the thief is determined and your bike is worth it they will break through any lock and no one is going to argue with someone with an angle grinder. Anyway if you lock your bike properly and use two different types of lock to lock the frame and each wheel, whether you have quick release wheels or not, unless the thieves have plenty of time not to be seen so identified they won't steal your bike when locked. This doesn't mean they won't use other tactics to get the bike off you but that is an entire different matter and one reason why I have a station bike.*If you don't know how to lock your bike so it makes it harder for thieves to steal there are plenty of videos on YouTube from different UK police forces plus cycling organisations and individuals who work in the bike trade in the UK and North America. 80-90% of the bikes I see locked up are locked up poorly which actually helps you if you lock your bike up properly.

Ordered this because it looked tougher than the other U-locks that can be had for $10-40. It might take a minute or two with an angle grinder (not verified) but it'll deter thieves with hacksaws and bolt cutters. Comes with a mounting clip that is screw on, not flimsy like the others that have a pull-tight mount. Comes with 5 keys (1 big, 4 small) which is nice but unnecessary for my use. I use this to lock my bike in the back of my truck (with a cable) and on campus. Easier to use than those circle-wound cable locks, and quite a bit more secure. On campus, this fits through the rear of the frame and rear wheel, securing all but the front wheel of my bike. This won't fit around your seat tube and rear wheel, you'll need something bigger for that. Great value for the price, I'd recommend this lock to any bike owner.
