New York Lock Standard

At 4.45 lbs, this is a substantial lock. While it adds noticeable weight to your bike or bag, that mass is a direct result of the 16mm hardened steel construction required for high-security protection.

The 4" x 8" dimensions are designed for a snug fit, which is actually a security feature because it leaves less room for thieves to insert leverage tools. It will comfortably lock your frame and rear wheel to most standard bike racks, but it may be too tight for locking around thick poles or trees.

The included FlexFrame-U bracket is versatile and fits most standard bike frames, but it may not accommodate oversized or unusually shaped tubing. It is best to check your frame geometry before installation to ensure a secure fit.

Kryptonite offers a Key Safe Program where you can register your key number online. If you lose your keys, they can ship replacements directly to you, provided you have registered your key code.

Yes, the protective vinyl coating acts as a buffer between the hardened steel shackle and your bike's paint job. It significantly reduces the risk of scratches and scuffs during daily locking and unlocking.

With a 9/10 security rating, this is one of the most robust locks available for urban environments. While no lock is impenetrable, this model is specifically engineered to withstand sustained attacks, making it a strong choice for high-risk areas.
