Sold Secure approved chain and U-lock kit

Everything you need for premium security on the move. We paired our bestselling Sold Secure Bicycle Diamond U-lock with our GKM 10mm heavy-duty chain – certified to Sold Secure Bicycle Gold. We know bicycles are a big investment, so why go cheap on security? The GKM chain features large 10mm hardened steel chain links that resist hacksaw and bolt cropper attacks. Pair that with our extra strong U-lock with hardened shackle and body, and you have a formidable force securing your bike.


Independently tested by Sold Secure

The 1480 HB U-lock is independently tested and approved by Sold Secure. Many insurers will request this certification to ensure your bicycle is secure, even when out of sight. Bicycle Diamond offers the highest levels of security against all common attack methods such as hacksaws and bolt croppers. It is also approved for use with motorcycles, meeting Sold Secure Gold. This is paired with a heavy duty hardened steel GKM 10mm chain that meets Sold Secure Bicycle Gold. The perfect choice for bicycles and motorcycles / scooters.


Police recommended

The 1480 HB and GKM chain were awarded “Secured by Design” – the official Police initiative to support reducing crime through good product design. The “SBD” logo shows the product meets strict standards through independent certification and good product design.


Ideal for general security

Not only will this kit protect your two wheeled investments, it is also ideal for general security, including sit on lawn mowers, ATV’s, trailers and anything else a chain can be securely placed around. (Note: Sold Secure Certification covers Bicycles – please call your insurance company for recommendations).
