Premium Hardened Steel Bike Lock - Essential Security for High-End Bicycles
Ensure unparalleled security for your bike with our top-tier Hardened Steel U-Lock. Designed to resist the most determined theft attempts, this lock features a shackle crafted from specially hardened steel with a substantial 0.55” / 14 mm diameter. It is engineered to protect against the toughest tools, including bolt cutters and metal saws.
Unlike common cheaper imports, our KOHLBURG lock's shackle boasts a premium construction, achieving the highest security rating of Level 15. This exceptional level of security is not only acknowledged but also recommended by the German Bike Association for safeguarding high-value bicycles.
We understand the importance of maintaining your bike's pristine condition. That's why our steel shackle is encased in a soft cover to prevent any scratches or damage to your bike.
Easy Transport with Special Mounting Bracket
Our bike lock comes with a versatile 2-Way Mounting Bracket that can accommodate the lock from two different positions. The practical design allows for slightly offset positioning, making it suitable even for bikes with smaller frames. The installation of the bracket onto the bike frame is quick and straightforward, thanks to the included and clear instruction manual. Please note: The bracket is designed to be mounted only on round frames with diameters ranging from 1” – 1.5” / 25 - 38 mm.
High Flexibility with Additional Spiral Cable for Enhanced Bike Security
Maximize the security of your bicycle with our versatile Spiral Cable, a perfect complement to our robust U-lock. This flexible loop cable, extending to 67” / 1.7 m, is designed to secure not only the bike frame but also both the front and rear wheels, along with any attached bicycle accessories. Thanks to its dual-looped ends, it can be effortlessly integrated with the U-lock for comprehensive protection.
Please be aware that while this cable offers increased flexibility and convenience, it inherently provides less protection compared to the U-lock.
No thieve in the world can break this lock!
Sorry, unfortunately, that is not true. And we are honest with you as we want you to correctly estimate the risk for your lovely bike to take the best measures. Of course, other lock producers promise unbreakable protection but this is simply not possible for any bicycle lock - no matter how big (just think of a thief with an angle grinder and enough time to spare).
However, what we offer to you is the highest possible security for a lock that can be conveniently carried with your bike. To make a long story short: With its combination of formidable strength and careful design, this bike lock is an indispensable security solution for any serious cyclist.

Das Schloss gefällt mir echt gut. Das Kabel könnte etwas dicker sein. Was mich stört, dass bei der Halterung zwei Schrauben nicht dabei sind.

Sehr gute Verarbeitung, massiv - daher natürlich entsprechend schwer.Dazu gibts mehrere Schlüssel und ein separates Sicherungskabel (Achtung, nicht so stabil wie das Schloß).Damit kann man Vorder u. Hinterrad mit abschließen oder sein Equipment schützen.Schloß ist natürlich mit Schutzhülle überzogen damit man sich sein Rad nicht beschädigt.

It's a light and easy to carry lock if you're on the go. The size allows you to easily lock both the wheel and frame to a bike rack. However, be aware that criminals are brazen these days and carry portable angle grinders which will cut through this in minutes if not seconds. I highly recommend you use a 2nd and thicker, more angle-grinder resistant lock for added security.

This baby ain't light weight, but it will depress a thief on site. It's reputation preceed it! I'm completely impressed and walk away from my bike with confidence. Anything less is just a target and a minor challenge.

This is a good, heavy-duty lock. They weren't mess'n around when they made this one. lol. However, the cable seems to be much smaller than advertised. I'm sure the measurements are correct in the product description, but I was still surprised by how short it actually was. Other than that, it's a great product & I'm glad I bought it.

The U-Lock heavy duty as indicated, I only hope the steel is properly hardened to ensure protection as needed.Disappointed in the quality of the lock mechanism itself as the Key is a fight everytime to get it in and out.The Cable included is extremely disappointing, very hard to use considering its stiffness in gards to its coil memory. Not really a useable product.

A perfect size for my escooter. It fits securely from signpost to behind the front wheel where the scooter hinge is. I’ve never been able to lock the body before, only the neck. I’m thrilled! And there’s a reason this lock is 10 out of 10 — it is beautifully constructed, like a German car. Well worth the $ for the peace of mind.

Very secure lock. The key unlocking takes some wiggling of the key to get it to open. Hopefully that will get easier over time. I have a comfort level leaving the bike for a short time.

PRO -- Showed this to neighbor, a county sheriff. "Amazing lock." "No one will steal your e-trike!"This heavy duty, 90° rght-angle lock, along with my 128db alarm all but guarantee would-be thieves will look for an easier target.CON -- Must be precise with key to un/lock. Otherwise, frustrating, especially in hot Florida sun with impending downpour and lightning.OVERALL -- AN AMAZING PRODUCT. HIGHLY RECOMMENDED.

Di semplice utilizzo, sembra sufficientemente robusto da svolgere correttamente la sua funzione. Ho apprezzato la lunghezza del lucchetto, molto utile per mettere in sicurezza la bici, ma di contro difficile da posizionare per il trasporto. Soddisfatto dell'acquisto

Con lo que pesa!2_Las instrucciones son inútuiles en mi ipinión.3_Abrir y cerrar el candado es una odisea. Puedo estar minutos intentando ponerlo.Sinceramente, si lo sé, no lo hubiera comprado. Tengo que buscarme otro que pueda utiliar con facilidad.I am extremely disappointed1_ The support is not strong enough to carry the weight, so I cannot use it and have to carry it on the bad. And it is really heavy.2_The instructions are awful. I could not understand them.3_To open and close it is an odyssey. i can spend minutes and minutes trying to lock the bike.A total waste of money in my opinion. I need to buy a new one that i actually can use.
