Kryptonite New York Lock M-18WL

The M-18WL is built specifically for high-theft environments, featuring an 18mm hardened steel shackle and a double deadbolt design that resists leverage attacks far better than standard locks. It is also Gold Sold Secure rated, which is the highest security certification available for bicycle locks.

Yes, this is a heavy-duty lock designed for maximum security, so it is significantly heavier than standard commuter locks. Most riders prefer carrying it in a dedicated frame mount or a sturdy backpack rather than on their handlebars.

The integrated sliding dustcover is a simple, effective feature that slides over the keyhole when the lock is not in use. It prevents dirt, road grime, and moisture from entering the cylinder, which keeps the locking mechanism smooth and prevents it from seizing up over time.

The M-18WL uses a high-security, anti-pick disc-style cylinder specifically engineered to resist picking and drilling. While no lock is entirely impenetrable, this design is significantly more resistant to manipulation than standard pin-tumbler locks.

The double crossbar design adds a layer of protection against twisting attacks, but it does not change how you lock your bike. You simply pass the shackle through your frame and a secure anchor point, then click it into the crossbar as you would with any other U-lock.
