OnGuard K9 Foldable Lock

Folding locks like the K9 offer a great middle ground. While a heavy-duty U-lock is generally harder to defeat, the K9's articulated tempered steel provides significant resistance to cutting and prying while being far more versatile for locking up against oddly shaped racks or posts.

The included frame holder is designed to be versatile, but it typically requires standard mounting points like water bottle bosses to attach securely. If your frame lacks these, you may need to use heavy-duty zip ties or carry the lock in a bag.

Yes, the 1125 mm length is quite generous for a folding lock. It provides enough reach to secure your frame and rear wheel to most standard bike racks, though locking both wheels and the frame simultaneously might be tight depending on the rack style.

The included frame mount is designed to hold the lock snugly to prevent rattling. However, ensure the strap or mounting bolts are tightened properly during installation to keep the unit secure over bumpy terrain.

OnGuard provides five laser-cut keys, which is more than most competitors, but you should still register your key code immediately after purchase. This code allows you to order replacement keys directly from OnGuard if you misplace your set.

Yes, the articulated steel bars are encased in a protective coating. This prevents the metal from scratching or marring your bike's frame during the locking and unlocking process.
