Everything you need for premium security on the move. We paired our bestselling Sold Secure Bicycle Diamond U-lock with our GKM 12mm heavy-duty chain – certified to Sold Secure Bicycle Diamond. We know bicycles are a big investment, so why go cheap on security? The GKM chain features large 12mm hardened steel square links that resist hacksaw and bolt cropper attacks. Paired with our extra strong U-lock with hardened shackle and body, and you have a formidable force securing your motorbike.


Independently tested by Sold Secure

The 100DY 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 12mm chain that meets Sold Secure Bicycle Diamond. The perfect choice for bicycles and motorcycles / scooters.
