Kryptonite New York Lock Standard - 16mm Steel Shackle

Kryptonite New York Lock Standard model 002154 is a black-and-yellow key-operated U-lock built around a 16mm hardened MAX-Performance steel shackle. Its compact 8 x 4-inch format and bright finish give it a recognizable profile on a bicycle frame.

Specifications and Included Hardware

The lock measures 8 x 4 inches and weighs 4.45 pounds, according to Kryptonite's model information. The 16mm shackle is made from hardened steel and uses a double deadbolt design intended to resist twisting and cutting attacks.

The package includes three stainless-steel keys and a FlexFrame-U mounting bracket. A sliding dust cover shields the disc-style cylinder from dirt and debris, while the protective vinyl coating helps prevent contact between the metal lock and a bicycle's finish.

Security Design and Daily Carry

REI lists the model with a pick- and drill-resistant disc-style cylinder, a hardened steel sleeve over the crossbar, and Kryptonite's 9-out-of-10 internal security rating. The same listing identifies it as a key lock for cycling and gives the weight as 4 pounds 7.2 ounces.

The dimensions favor a standard bicycle frame and wheel-locking setup rather than unusually wide clearance. The FlexFrame-U bracket provides a dedicated mounting point, so the 4.45-pound lock does not need to ride loose in a bag.

Price and Warranty Position

REI lists the Kryptonite U New York Lock Standard U-Lock at $169.95 as of 09/23/2026. That places the model above Kryptonite's KryptoLok Standard U-Lock, which REI lists at $79.95, while the two products share the same general U-lock format.

Kryptonite's US warranty information identifies Schlage Lock Company, LLC, through its Kryptonite division, as the company extending coverage for qualifying products. REI describes the New York Lock Standard as carrying a lifetime warranty, subject to the manufacturer's terms and limitations.

Where the Lock Fits

The New York Lock Standard is a heavy-duty bicycle U-lock for riders who want a thicker shackle and reinforced locking hardware than an entry-level model provides. Its 16mm steel shackle and 4.45-pound weight show the trade-off directly: more material and security-oriented hardware add noticeable carrying weight.

Compared with the smaller KryptoLok Standard U-Lock, the New York model costs $90 more at REI and weighs 4 pounds 7.2 ounces. The result is a better fit for fixed parking, commuting, and overnight bicycle storage than for riders who prioritize the lightest possible carry setup.
