Security or Flexibility? You Can Have Both! The Novosibirsk U-lock combines the high protection of a U-lock with the flexibility of a cable lock - recommended by the German Bike Association. 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.

SECURITY FIRST, NO NONSENSE GIMMICKS – The D-lock is designed to protect high-quality bikes - no more and no less. Hence, this D lock is no lifestyle accessory with a fancy design or exciting gimmicks. We are simply focussing on security by using the strongest available steel and a safe multi-disk cylinder, with security certification from the German Bike Association. A secure bike u lock does not need anything else.

SOLID STEEL FOR SECURITY LEVEL 15 OUT OF 15 – In contrast to many other U locks, we do not use light steel with reduced weight & security. There is simply no short-cut for a secure lock - a bicycle lock needs to be massive & sturdy to prevent theft. Compared with other bike locks, our ulock shackle is heavy duty with a diameter of 0.55” / 14 mm solid hardened alloy steel and, thus, is especially resistant against bolt cutters & metal saws. The “price” of this high security focus is a lock weight of 3.3 lbs / 1.5 kg, still being ideal s a scooter lock, motorcycle lock, ebike lock and bike lock.

SECURE MULTI-DISC CYLINDER – Instead of relying on the typical insecure car key cylinder, we equip our lock with a secure multi-disc cylinder. Multi-disc cylinders are extremely difficult for thieves as they need to align several discs at the same time to pick the lock. Additionally, the striking T-structure of the 2-chamber locking system protects the lock against drilling attacks. 3 keys are included.

LARGE SHACKLE FOR EASY LOCKING - With an outer size of 6.7" x 13.5" / 17 x 34.3 cm, the lock is comparatively large, making it easier for you to lock your bike to fixed objects. Practically, your bike varnish is protected by the soft protective cover of the shackle. Furthermore, the included 2-way bracket allows to hold the lock from 2 directions (see picture). This enables an easy transport even with small frames. The bracket is suitable for round frames with a diameter of 1”-1.5” / 25-38 mm.

ADDITIONAL BIKE LOCK CABLE - The handy spiral security cable with a length of 67” / 170 cm and a thickness of 0.3” / 8 mm ensures that you can also connect your front wheel and bicycle accessories such as trailer, child seat & helmet. Practically, heavy duty lock and cable can be used separately. Greatly suited to protect e-bikes, pedelecs, electric bikes, touring bikes, trekking bikes & bike trailers.
