Kryptonite Ring Lock

On its own, this ring lock only immobilizes the rear wheel to prevent someone from riding your bike away. However, it includes a plug-in feature that allows you to attach the included 1200mm chain, which you can then wrap around a stationary object like a bike rack for full security.

It means you can remove your key from the lock even when the lock is disengaged. This is convenient if you prefer to keep your key on a keychain rather than leaving it dangling in the lock while you ride.

This lock is designed to mount directly to the frame, typically using the existing mounting holes on the seat stays of bikes equipped with rim brakes. Before purchasing, ensure your bike frame has the necessary braze-ons or mounting points to accommodate a standard ring lock.

No, this is primarily designed as a deterrent for quick stops and daily urban commuting. For overnight or high-risk areas, we recommend using this in combination with a heavy-duty U-lock or chain lock to provide multiple layers of security.

The chain is 5.5mm thick and 1200mm long, striking a balance between portability and security. It is substantial enough to deter opportunistic theft but light enough to carry comfortably while you ride.
