Kryptonite New York U-Lock review

Submitted by on January 24, 2011 – 10:57 am3 Comments

While contemplating the Grim Subject of Bike Theft I realized I should quit rolling the dice by relying on a flimsy bike lock, and instead buy something that would actually deter a bike thief.  So I read up on the subject and decided on the Kryptonite New York U-Lock Fahgettaboutit, affectionately known as the NY FU.  So far so good.

The first thing you’ll notice is the NYFU is beefy and weighs in at about 4.5 pounds. If nothing else you can put a bike thief in a coma by smacking them upside the head with one.  The compact dimensions (3.25″ x 6″ , or 8.3cm x 153cm) make it difficult for a bike thief to get much leverage with their tools of grief.

During early product testing a bike was locked up with the Kryptonite New York U-Lock in Greenwich Village where it was left for 30 days. Pretty much everything was stolen from the bike yet the thieves could not break the lock.

How to:
You want to position a U-lock inside the rear triangle of the frame by placing it around the rear tire and rim.  When used like this the wheel cannot be pulled through the rear triangle, which means neither the rear wheel nor the frame are going anywhere.

A good U-lock is probably your best bet for securing the bike but it certainly does not protect all the components.  You’ll still need a strategy for locking the front wheel (and saddle if yours is one a thief might covet).  We’re not in New York or even in the top 10 cities for bike theft, so I’ll be using a lighter solution (likely a cable lock) to secure the front wheel and saddle.

Bottom Line:
I don’t typically leave my bike out of my sight, which can be a real hassle.  Having to sit near a window in a coffee shop or bar where I can keep an eye on it is a less than elegant way to enjoy cycling.  But now I feel like I have a bike lock that will give me confidence to leave the bike and, well, fahgettaboutit.

Includes three keys and one lights up

Manufacturers specifications:

Chris started riding a bike again when he noticed the Preston Ridge Trail being constructed across the street from his house. Since then he co-founded Biking in Dallas, has gone through countless Craigslist bike projects (some better than others) and can be found pedaling around town on a Electra Ticino with a camera in tow.
