Features

  • 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.

  • The Arvydas Sabonis of Bike Locks.
After kissing two Kryptonite Keeper locks goodbye, I ordered the KOHLBURG U-Lock. It arrived yesterday, and the difference between it and the Keepers is ’UGE. This thing’s a beast—but with a soft touch. Locking and unlocking is smooth, effortless. The Arvydas Sabonis of bike locks. I can now rest easy knowing my KOHLBURG is locked to the wheel of my 2006 Kymco People 150 intimidating all comers and proudly resisting rain, sleet, and grime. It’s a great lock, folks. ... show more

  • Superb product. Must be precise w key to lock or unlock.
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. ... show more

  • Lock itself is fine, but the frame mounting bracket is weak for such a heavy lock
The lock seems to have high quality so far, but the mount cannot hold the lock securely to the frame. The lock will wobble a bit when mounted simply because it is relatively large and heavy, and it is mounted to the frame only at one point. I will use a bungee cord for additional securement.

  • Cannot be cut!
Expensive but worth it!

  • Decent
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. ... show more

  • The Best!!
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. ... show more

  • Needs a little engineering improvements.
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. ... show more

  • Top security
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.
