La marca Kriptonite es una de las mas importantes y con gran experiencia en seguridad , en este caso para las bicicletas nos ofrecen un candado en forma de U muy seguro, resisten y funcional, manejando un precio accesible por el vendedor, se los recomiendo bastante ya que ofrece un alivio al dejar su bicicleta, claro tomando en cuenta aspectos de la localidad donde se encuentran, el lugar donde la encadena etc, pero es imponente para cualquier persona de lo ajeno, un aspecto a tomar es que cuando lo comiencen a usar, colóquenle afloja todo o dw40 para que no haya roces con la llave y la entrada esto por lo nuevo del articulo.

Cet antivol semble solide. A l'usage le U est un peu court pour bien attacher un VAE à un point fixe. Le câble permet d' y arriver mais c'est probablement moins sur qu'avec le U.

This is a seriously solid lock that gives you a real sense of security. The U lock alone is thick, heavy, and feels virtually tamper-proof. The included flex cable is a great addition, giving you more options to loop through your wheels or around awkward railings or posts. I’ve used it to lock both my frame and rear wheel with the U lock and then looped the cable through the front wheel. That versatility makes a big difference in urban areas where secure anchor points aren’t always ideal. While it is heavier than cheaper alternatives, the added weight feels justified by the protection it offers. I’d much rather carry a little extra bulk than come back to a missing bike. The lock mechanism is smooth, and the key turns easily without sticking, which I appreciate after past frustrations with cheaper locks. Pros: Heavy-duty and high quality Flexible locking options with included cable Smooth key operation Cons: A bit bulky for smaller backpacks It might be overkill for low-crime areas

I bought the previous version of this cheaper U-lock from Kryptonite back in 2011. I live in a city where bike thefts are extremely common and yet my bicycle (a Nishiki hybrid) was never stolen. Unfortunately my Kryptolok developed the key jam issue and no amount of lubricant or even using the spare key helped. I therefore went for this newer model which now has a Gold rating instead of a Silver rating of the earlier model. I was pleasantly surprised that the bracket had been improved as with the earlier model I always had issues with detaching the lock from it. This new bracket is more adjustable, easier to tighten and the lock detaches effortlessly. The U-lock itself is nicer as now the key hole is at the the center of the lock which means you are less likely to put too much pressure on the key when locking and unlocking. The key hole cover is also much easier to use as its just a small cover you slide on top of the key hole. I did think about buying a slighly more expensive and secure model but in my opinion this is probably the best value bike lock you can find (the general opinion at least in my location seems to be that U-locks are better than any other lock type and Kryptonite is usually more durable than Abus or some other brand). Highly recommended for the price!
