Product Description

Big city riders need big city protection, as would-be thieves aren't intimidated by just any lock. Enter the Kryptonite New York LS U-lock, which features a 16mm hardened Max-Performance steel shackle designed to resist bolt cutters and leverage attacks. Ideal for anyone who lives in moderately high crime areas, the New York LS boasts an 11 ranking on the Kryptonite 1-12 comparison system, which ranks the varying levels of security within the company's product range. A lock that ranks 1 on the Kryptonite scale might work if you live in the burbs and have a Rottweiler parked next to your bike or motorcycle. However, city dwellers demand extreme protection, which is why the New York LS is built for serious deterrent security.

The U-lock offers such additional security-enhancing features as a high-security disc-style cylinder; a double deadbolt locking system for extensive holding power; a protective vinyl coating; and a sliding dust cover that protects and extends the cylinder life. As a bonus, the lock comes with three keys, one of which is lighted with a high-intensity bulb that makes it easy to unlock the New York LS after dark. The New York LS U-lock measures 10.25 by 4 inches.

The Legendary Durability of Kryptonite Locks
The first big test for Kryptonite locks came in 1972, when Kryptonite founder Michael Zane directed the Second Avenue Bicycle Shop in New York City to lock a three-speed bicycle to a signpost in Greenwich Village. Although thieves immediately stripped all of the bicycle's removable parts, the bicycle itself remained for 30 days and 30 nights. The Kryptonite lock and the bike frame were still in place, even though the lock had been attacked numerous times. The publicity gave Kryptonite the boost it needed and forever changed the face of bicycle security.

Twenty-two years later, Kryptonite returned to the streets of the Big Apple to test its latest innovation, the New York lock. In April 1994, the New York Post laid down the ultimate challenge: Could Kryptonite's New York lock last 48 hours on the toughest streets of New York? In a city where more than 100,000 bikes are stolen each year, Kryptonite and the Post locked a brand-new, bright green Univega road bike worth $600 to a parking meter in the East Village--the Bermuda Triangle of New York bicycle thievery. For a full 48 hours, the bike remained locked on the corner of Avenue A and 11th Street. Zane and Neil McDaid, director of product development and design for Kryptonite, watched from around the corner as the bike came under every possible means of assault, stumping thieves at every turn. After 48 hours the bike remained intact except for the gear derailleur, which had been stripped off. The lock showed definite signs of abuse, but it had not failed. The New York lock had met the Post's challenge.

Not satisfied with the length of the test, Zane moved the bike to SoHo for another six days and, finally, uptown near the Lincoln Center. Even in these high-theft areas the properly locked bike lasted another three weeks before being pulled off the streets by Zane and McDaid. The Post also ran the New York lock through a battery of street tests using common bike theft tools: a 4-foot bolt cutter, a crowbar, and a hammer. The non-Kryptonite locks cracked in seconds, but all methods failed on the New York lock, even the monstrous bolt cutter, which was rendered useless with large dents in its jaws.

About Kryptonite
In the early 1970s, Michael Zane was a free-spirited, bearded kid with a VW van and a big idea for a new kind of lock. He traveled thousands of miles showing the unique U-shaped locking device and spreading his passion for bicycle security to bike dealers all around the country and forged lifetime relationships. The company soon expanded its product line to include power sports, hardware, and snow sports security. Through innovative product designs, cutting-edge marketing savvy, legendary customer service, and pure fanaticism for security, Kryptonite grew with a cult-like following. In 2001, the company that was started in a VW van was purchased by industry giant Ingersoll Rand and became a flagship brand in the company's Security Technologies sector. Publications such as Bicycling, Fortune, The Wall Street Journal, US News & World Report, and a host of others continued to tout Kryptonite products as the best on the market.

The company's dedication to its customers is best represented by its actions during the fall of 2004, when it was discovered that the industry-standard tubular cylinder could be compromised, at times, with a household item. Kryptonite flew into action, created a voluntary lock exchange program, and replaced more than 400,000 locks in 21 countries for free. In essence, the company redesigned the equivalent of nine years worth of new products in just 10 short months. Kryptonite is the only company in the world that offered such a comprehensive plan to customers, taking its "legendary customer service" pledge to new heights.

5.0 out of 5 stars Wow...this thing seems very secure, June 3, 2010

Being in Cincinnati I am usually told that a cable lock is acceptable to lock up your bike since the city isn't known for many bike thefts unlike Chicago or New York but I felt it was better to be safe than sorry. This is a great lock and when used properly, I feel safe leaving it most anywhere I go. I have had no problems with the key since it operates smoothly.

For some reason, it is almost impossible to find out the lock weight and total dimension online. Most measurements only give you the inner lock measurements. The lock weights 4 lbs 5 ounces and is 6 5/8" x 12 7/8".

This lock is excellent for city use. It's convenient to carry (I either strap it to my rack or throw it in a backpack), and secures both wheel and frame to a rack or sign post. Can't swing a light post, but so what. I used the Krypto chain for many years and found it to be waaay to much of a hassle to lug around.

Tip: This lock sticks like crazy after getting wet the first time. WD40 it a bit and it works like a charm.

4.0 out of 5 stars High Security And Heavy U-Lock For Unattended Bikes, May 5, 2011

By

This review is from: Kryptonite Ny 3000 Mc Lock (Sports)

I will start my review by saying that as expected, the lock is extremely sturdy and heavy, weighing 4 pounds 5 ounces and comes with three keys. The shackle is 3/4" thick and the locking mechanism is 1 1/2" in diameter, which is a great deterrent for most of the opportunity bike theft situations since it should be extremely hard for someone to defeat the lock without the use of some power tools. The interior dimensions of the shackle are 4" wide and 10 1/4" from the top center bottom of the shackle to the top of the yellow locking mechanism which is longer and wider than most. The yellow locking mechanism also removes completely from the double-post shackle when unlocked which allows for easy securement of the the frame and rear tire (and the front tire if you remove it) to most posts. The lock exterior dimensions are 6 5/8" x 12 7/8".

The entire U-lock is coated with a durable vinyl coating, which has held up well even after the lock falling off of the bike twice after being jolted off by heavy bumps. My only gripe is the black cover on the locking mechanism rotates easily if twisted and can keep the shackle from locking, not a very big issue if you handle the locking mechanism by the yellow cover instead when placing and removing the lock. The bottom of the lock has a sliding key hole cover which is easy to operate and locks in and out place. The lock uses a high-security type key which makes the lock very pick-resistant and should be far more secure than the previous round tumbler designs from Kryptonite (some can be opened using a Bic pen!). One of the keys has a built in LED light which is very bright if you need to use it at night. If you register the lock key code on Kryptonite's Website you can receive a replacement should you ever lose the keys that come with the lock. The theft guarantee had too many restrictions to be useful, so I wouldn't use that as a primary reason to purchase this lock.

The reason I didn't rate the lock 5-stars is at first the locking mechanism would stick at times, making it difficult to remove the key. I used some silicone spray in the key hole which has definitely helped. The other issue is that since this is such a large and heavy lock, finding somewhere to secure it on your bike isn't easy. I hang the lock from a bracket on the handlebars that is for a front basket and the weight of the lock is sufficient to keep it from moving unless you go over a very large bump in the road. Overall this would be an excellent and high security lock for anyone leaving a bicycle unattended for long periods of time or in a high crime area. For other situations like a quick trip to the store it's probably overkill, but is great for piece of mind as long as you don't mind the added weight on your bike and have a way to carry it.

If you don't have a convinient place to carry the lock on your bicycle and don't mind a shorter length U-lock, the Kryptonite New York Standard Bicycle U-Lock with Bracket ( 4-Inch x 8-Inch) might be a better choice since it basically a shorter (4" x 8") and a bit lighter (3.9lbs) version of the New York LS U-Lock, with the same 16mm shackle and includes a bracket to mount the lock on your bike.
