Overview
Is the Kryptonite New York the Ultimate U-Lock?
The Kryptonite New York U-Lock is the brand's highest-security U-lock, built around a 16mm MAX-Performance hardened steel shackle, the thickest in Kryptonite's lineup, engineered to resist the most aggressive cutting and prying attempts. A double deadbolt locking design engages on both sides of the shackle, eliminating flex and maximizing structural integrity under attack. The disc-style cylinder resists picking and drilling, and the compact shackle dimensions reduce the space available for leverage tools.
At 3.25 x 6 inches, the tight internal clearance limits the working room a thief can exploit, making pry-bar and jack attacks significantly harder. The keyed mechanism ships with three keys, including one with an integrated LED for low-light use. This is Kryptonite's answer for riders parking in high-crime urban areas, overnight in cities, or anywhere a lesser lock simply will not do the job.

FAQ
Good questions
Get to know Kryptonite

There's more to Kryptonite than this one product. Our Kryptonite page has the full Kryptonite lineup we carry and more about the brand.
Visit the Kryptonite page →What makes the New York U-Lock different from the Evolution Series?
The New York uses a 16mm shackle vs the Evolution's 13mm, and carries a security rating of 10 out of 10. It is Kryptonite's top-of-the-line U-lock, built specifically for high-crime environments.
Why does a smaller internal dimension make the lock more secure?
Less internal space means less room to insert tools like hydraulic jacks or pry bars, which are the most common method of forcing a U-lock open. The New York's tight clearance is a deliberate security feature.
Does the New York U-Lock come with frame mounting?
A transit frame mounting bracket is available separately and is compatible with the New York U-Lock for on-bike carry during your ride.
