The company began its manufacturing house in 1973 and since then has been manufacturing some of the best mountain bike security locks.

Being a New York City dweller, I have to cope with thieves lurking everywhere all the time. For my mountain bike, I trust Kryptonite Kryptolok New York Standard U-Lock and for good reasons. In this Kryptonite Kryptolok New York Standard U-Lock review, let me explain why!

Unique Design Makes it a Favorite

Kryptolok New York Standard U-Lock has a conventional design of U-shaped steel. The steel is 13mm thick. Both the tires and/or the frame of the mountain bike can be locked using the hardened steel.

The design is stable and the steel is almost impossible to penetrate. Although it is the standard edition, it took my friend 43 staggering seconds to cut through this lock.

From me, it receives a rating of 8.5 on 10.

Incredibly Versatile Lock!

Kryptonite has another version of the Kryptolok Standard New York Bicycle named “New York Fahgettaboutit U-Lock” but this one is just as versatile as the latter. It has a width of 8 inches and a height of 4 inches.

You can easily lock down your front tires with the frame, the back tires or just frame back and front tires at once with this lock without problems.

This clearly sets apart the Kryptonite Kryptolok New York Standard U-Lock from others as you can lock your bike with anything as long as there is only one bike.

Gothamist claims that more than 592 bike thefts occurred during early 2015. It is an alarming number. To solve this, Kryptonite has covered some ground with its Kryptonite Kryptolok New York Standard U-Lock for cyclists and mountain bikers. It is recognized as one of the top shelf locks for mountain bikes

How to Operate this Lock?

As a standard lock, opening and closing this lock is no trouble at all. It works on “Dual Locking System”. The crossbar needs to go within the U-Shaped “Hollow” bar and you are done. It is locked.

Do keep your ears open for an audible click sound. If you can hear the sound, your lock is perfectly in place to protect your mountain bike.


  • The design allows quick locking.
  • You can use it in urban areas.
  • Hacksaw and cutter bolts can’t penetrate this lock.


  • A bit heavy for my liking.

Frequently asked questions (FAQ )

Q. Is the flex frame bracket of Kryptonite Kryptolok New York Standard U-Lock different than others?

A. Other locks from Kryptonite have Flex frames which can move back and forth when used. This one remains steady.

Q. How can people be sure that it is actually Kryptonite Kryptolok New York Standard U-Lock and not the Kryptonite MC Lock?

A. If you measure the lock, you’ll find that the standard New York U-Lock comes with 16mm hardened steel. But the MC lock has 18mm hardened steel. So, that is the subtle difference you should look for when purchasing.

Final Verdict

If you want to give a thief a run for his effort, purchase Kryptonite Kryptolok New York Standard U-Lock. It took me and my friend quite some time to break through its defenses. Sure it is a tad bit expensive but when you consider the level of protection it grants your bike, it is worth every dollar you spend., one of the top review blogs online awarded this bike lock as # 1 best model available now.

Buying this once settles the security issue of your bike for at least 15 or 20 years in my opinion. I am gladly recommending it to any mountain bike enthusiast out there.
