FAQ

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.

Best For

Urban riders who park overnight, commuters locking up in high-crime neighborhoods, and cyclists with high-value bikes who want Kryptonite's maximum-security U-lock without compromise.
