Maximum Reach and Maximum Security for High-Theft Zones
The Kryptonite New York LS (Long Shackle) is the largest and most secure U-lock in Kryptonite's lineup, designed for urban environments and high-crime areas where overnight parking and maximum confidence matter. At 4" x 10.25", the expanded shackle opening accommodates thick posts, cable loops, chain loops, and racks that smaller locks cannot reach, giving you flexibility in choosing where to secure your bike. The 16-millimeter hardened MAX-Performance steel shackle and patented double deadbolt resist bolt cutters, leverage, and twist attacks, while the highest-security disc-style cylinder defeats picking and drilling. At 4.85 pounds, this is a substantial lock, but the weight reflects the engineering: every component is hardened, and the oversized crossbar sleeve eliminates weak points.
Rated 9/10 on Kryptonite's security scale and eligible for $4,000 in anti-theft protection on bicycles (or $1,500 on powersports), this is the lock used by NYC messengers, e-bike owners protecting serious investment, and riders in the most theft-prone neighborhoods. It comes with three stainless steel keys, one with an LED light for low-visibility locking. The long shackle design means it does not fit a standard FlexFrame-U bracket, so plan your carry method accordingly—a separate mounting solution or bag carry is necessary.
Uncompromising Security With Maximum Reach
- Sixteen-millimeter hardened MAX-Performance steel shackle offers maximum resistance to cutting, leverage, and brute-force attacks.
- Patented hardened double deadbolt design provides additional protection against twist and cut attacks on the shackle ends.
- Highest-security disc-style cylinder is pick and drill resistant, defending against manipulation at the lock face.
- Four-inch by ten-point-two-five-inch interior dimensions accommodate thick posts, cable loops, chain racks, and infrastructure that smaller U-locks cannot reach.
- Oversized hardened steel sleeve over the crossbar eliminates the traditional hollow-point vulnerability.
- Sliding dustcover extends lock life and protects the cylinder from environmental debris.
- Protective vinyl coating prevents scratches to your frame and other bikes parked nearby.
- Three stainless steel keys: two standard "I" keys and one with high-intensity LED bulb and replaceable battery for keyway visibility in low light.
- Registered through Kryptonite's Key Safe Program for spare key access and protection confirmation.
- Not compatible with FlexFrame-U bracket; alternative carrying solutions required.
