OnGuard OG 5815

The 12mm hardened steel shackle is encased in a protective coating. This barrier prevents the metal from directly contacting your bike frame, ensuring your paint job stays intact while locked.

The cable is designed to secure your front wheel or accessories like a seat or helmet. You loop it through these components and then secure it within the U-lock mechanism for comprehensive protection.

The quick-release mounting bracket is designed to fit most standard bicycle frame tubes. However, if your frame has an unusual geometry or oversized tubing, you may need to find an alternative mounting position or carry the lock in a bag.

The lock features an automatic dust cover that keeps debris out of the cylinder, which is your first line of defense. If the key feels stiff, you can occasionally use a dry silicone-based lubricant to keep the internal mechanism moving smoothly.

The lock comes with two laser-cut keys. Because these are high-security keys, it is highly recommended that you register your key code with OnGuard immediately after purchase to facilitate ordering replacements if needed.
