Kryptonite Kryptolok Standard Bike U-Lock with Cable, Heavy Duty Anti-Theft Bicycle U Lock, 12.7mm Shackle and 10mm x 4ft Length Security Cable with Mounting Bracket and Keys

The product you are showing is a Kryptonite brand U-lock, most likely a Kryptolok model, which includes an extra cable and a carrying bracket. Kryptonite Kryptolok U-Lock with Cable Review The Kryptonite Kryptolok is one of the most recognized bike locks due to its combination of security, durability, and ease of use. Here is a detailed review: Design and Construction The Kryptolok U-Lock is designed to be tough and reliable. The main body of the U-lock is made of hardened steel, making it difficult to cut with hand tools such as bolt cutters. Its size is suitable for locking both the bike frame and a wheel, providing excellent protection in urban or high-risk areas. Extra Cable The package includes a flexible steel cable that can be used to secure the front wheel or any additional accessories, adding an extra layer of security. While the cable isn't as robust as the U-lock, it's a useful addition to protect various bike components. Locking Mechanism The lock features a double locking system that secures both ends of the U-bar, increasing its resistance to twisting attacks. It also comes with two keys, which is handy in case you lose one. Carrying Bracket The included bracket allows the lock to be carried on the bike frame without any problems, which is ideal for cyclists who prefer not to carry the lock in a backpack or bag. It's easy to install and keeps the lock secure during the ride. Pros: • High resistance to cutting and theft attempts. • Includes an additional cable for added versatility. • Easy to transport thanks to the bracket. • Good balance between price and security. Cons: • The weight can be a bit high, although this is normal for locks of this type. • The cable is not as secure as the U-lock for protecting more expensive components. Final Verdict The Kryptonite Kryptolok is a solid choice for those looking for a high-quality, high-security lock for their bike, especially in combination with the additional cable. It is ideal for urban areas where the risk of theft is higher.

This lock is so good. I'm coming from the Evolution model which I loved and secured my bike, but someone stole the entire rack it was locked to and the price went up so I went with this model lock instead. The mounting adapter that goes onto your bike is great! I keep the lock clipped to it as I ride around, the key goes on my key ring and it fits well and keeps my bike secure. I did have some trouble using the key or undoing the lock, so I sprayed some WD40 on the part that comes apart and in the keyhole. Then I used teflon dry bike chain lube on the same parts and in the keyhole, put the key in there and turned it a bunch. Now it works perfectly and is easy to lock or unlock! If you need a solid U-Lock with a bike frame mount - THIS IS THE ONE!

We mounted these to our Lectric XP 3.0. Because of the awkwardness of the ebike frame, we should have went with a wider and/or longer lock. It isn't long enough to really lock a wheel real good, and isn't wide enough to secure the step through mid frame. This would be a good secondary lock for the XP 3.0, but not the primary. The supplied mount works great and keeps the lock in place when we travel.

I would have given this item 5 stars but it came without the bracket to attach to the bike frame. I have used Kryptonite brand locks in the past and am very happy with their quality.

Great product!

One of the most user friendly locks I've seen that leaves you without worrying if your bike would be stolen. Even though the width of the bar is thin it seems very dense which might help in case an unexperienced thief tries to break it. Unlocking this bike with the key that is given is easy and doesn't require that much of a struggle. All in all, its an affordable lock that gives you more than what you pay for.

Standard kryptonite bike lock is heavy duty

Lock is great and tough, I just wish my town invested in racks with larger loops so I could actually use the cable to attach my bike to the secure stands.

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.

Se ve de excelente calidad, es pesado, pero lo esperaba. Tamaño perfecto para no tener problemas al aparcar la bicicleta, ampliamente recomendado. Veremos su funcionamiento en estos días.

Safest lock out there, comes with 2 keys and with holder to be mounted on the bike frame

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
