Product Information

Full details

The Urban U4K120 Anti-theft Chain is an essential security solution for motorbike, scooter, and bicycle owners who need a reliable way to anchor their vehicle to fixed objects. Featuring a hardened 10mm square-section chain and a robust double-locking padlock, it offers high-level resistance against cutting and picking; however, users should be aware that the high-strength steel construction results in a significant weight, which may affect portability for some riders.

FAQs

Is the Urban U4K120 suitable for motorcycles?

Yes, it is designed for motorcycles, scooters, and bicycles.

Can the fabric sleeve be replaced?

The sleeve is integrated for protection, but it can be cleaned with mild soap and water if it becomes dirty.

How do I secure this to a wall?

It is recommended to use the chain in conjunction with a fixed wall or ground anchor for maximum security.

What should I do if I lose my keys?

Contact your authorized dealer or the manufacturer's support team using your key code card provided at purchase.

Does the chain rust?

While the steel is treated, it should be kept dry and lubricated to prevent surface oxidation.

Troubleshooting

The key is difficult to insert or turn

Clean the keyway with compressed air and apply a small amount of graphite or silicone lubricant to the cylinder.

The padlock feels stiff during locking

Ensure the shackle ends are properly aligned with the locking holes and that no debris is obstructing the slots.

Pros and Cons

Pros

  • High resistance to common theft tools like bolt cutters
  • Ample 120cm length for versatile parking options
  • Protective sleeve prevents vehicle damage
  • Weather-resistant dust cover for the padlock

Cons

  • Heavy weight can be cumbersome to carry on smaller vehicles
  • Requires significant storage space when not in use
  • Rigid links can be difficult to maneuver in tight spaces

Setup, Compatibility & Care

To set up your security, thread the chain through your vehicle frame and then around a permanent, immobile structure. Insert the shackle into the padlock until you hear the locking mechanism engage. For maintenance, keep the lock cylinder clean and occasionally apply a light silicone-based lubricant to ensure the internal pins move freely. Always ensure the dust cover is closed after locking to prevent internal corrosion from road grit and rain. The chain is compatible with most standard bicycle frames, scooters, and motorcycle wheels.
