Kryptonite Ring Wheel Lock with Plug-In Chain

A ring lock mounts directly to your bike frame and immobilizes the rear wheel, preventing anyone from riding it away. By adding the plug-in chain, you secure the frame to a stationary object, which provides the comprehensive protection a standard U-lock offers but with a more integrated, streamlined setup.

This lock is designed to mount to the seat stays of most bicycles that have pre-drilled mounting holes. Before purchasing, verify that your bike frame has the necessary mounting points near the rear wheel to accommodate the ring lock mechanism.

The included chain is 1200 mm long, which is generally sufficient for standard bike racks, signposts, and parking meters. While it offers good flexibility, it may be tight if you are trying to secure your bike to an unusually wide or oversized object.

Yes, the ring lock is compatible with both Kryptonite and AXA plug-in accessories. This gives you the flexibility to swap out the chain for a different length or style if your security needs change.

No, this is a non-key retaining design. You can remove the key once the lock is unlocked, so it won't dangle or get in the way while you are cycling.

The total system weighs 3.65 lbs. Because it mounts directly to the frame, the weight is distributed low on the bike, which helps maintain stability and balance while you ride.
