What is the thickness of the shackle?

What type of steel is used in the lock?

The shackle, housing, and structural parts of the locking mechanism are all made of specially hardened steel.

How does the lock holder attach to the bike?

The ABUS USH holder mounts easily onto the frame tube with a diameter of 15 to 35 mm.

Is the Cobra cable included?

What makes the lock resistant to tampering?

The lock features a high-quality lock cylinder designed for high protection against manipulation, such as picking, and uses specially hardened steel components.

How should I maintain the lock?

Keep the lock cylinder clean and lubricate it periodically with a graphite-based lubricant. Wipe the exterior with a damp cloth and dry thoroughly.

Troubleshooting

Lock is stiff or difficult to open/close

Ensure the lock cylinder is clean and free of debris. Apply a small amount of graphite-based lubricant into the keyhole and work the key in and out several times. Check that the shackle is aligned correctly before attempting to lock.

USH holder rattles during ride

Check that the USH holder is securely fastened to the frame. Ensure the U-lock is fully seated in the holder. Some minor adjustment to the bracket's position might help eliminate noise.

Key will not insert or turn

Verify you are using the correct key. Check the keyhole for any obstructions. Ensure the shackle is fully disengaged before attempting to use the key.

Setup, Compatibility & Care

Setup: The USH holder can be easily mounted onto the bike frame tube using the provided hardware. It is designed to fit frame tube diameters between 15 to 35 mm. Ensure the bracket is securely fastened before riding.

Compatibility: This U-lock is compatible with most standard bicycle frames. The USH bracket's adjustability ensures it can be fitted to a wide range of tube sizes. The included Cobra cable has loops suitable for securing items.

Care: To maintain optimal performance, keep the lock cylinder clean and free from dirt and debris. Periodically lubricate the lock cylinder with a graphite-based lubricant or a specific lock lubricant. Avoid using oil-based lubricants, as they can attract dirt. Wipe the exterior of the lock with a damp cloth as needed, and dry thoroughly.
