Kryptonite Ring Wheel Lock

No. The ring lock immobilizes the rear wheel to prevent riding, but it does not secure the bike to an immovable object. It is best used as a secondary security measure or for very quick stops where the bike remains within your line of sight.

The lock uses a flexible mounting bracket designed to accommodate most standard bicycle frames. However, you should ensure your bike has the necessary mounting points or clearance on the seat stays to attach the bracket securely before purchasing.

We do not recommend using a ring lock as your sole security device, especially in high-theft urban areas. It is designed to stop opportunistic theft by preventing the bike from being ridden away, but it should be paired with a U-lock or chain for comprehensive protection.

Once mounted, a steel bolt slides through the spokes of your rear wheel when you turn the key. This physically blocks the wheel from rotating, effectively immobilizing the bicycle until you unlock it.

Installation is straightforward and typically requires only basic tools. The flexible bracket allows for some adjustment to ensure the lock aligns properly with your wheel spokes, but you will need to ensure the bolt clears your tire and rim width during setup.
