Kryptonite KryptoLok Series 2 LS U-Lock Review: Best Bike Lock within Budget?

Lack of security on your bike can result in the parts or the whole bike being stolen. On the busy streets of our city, bike theft is more than a frequent occurrence we see.

People often use shackle lock systems and a pair of chains to tie their bikes with another one or with the stand. For me, I use Kryptonite Kryptolok LS U-Lock as the protection lock. It is one of the robust locks Kryptonite has brought about.

Kryptonite Kryptolok Series 2 LS Heavy Duty Bicycle U Lock with...
  • 13mm hardened PERFORMANCE STEEL SHACKLE resists cutting and leverage attacks
  • Reinforced hardened CROSS BAR DESIGN provides increased protection

The company takes pride in calling this lock “Nearly Unbreakable.” In this review article, I’ll go through few benefits this lock offers people.

The Design of this Lock

Kryptonite KryptoLok Series 2 LS U-Lock There is nothing too complicated in the design of this lock. There is a Steel U-Bolt shackle that is 13mm in thickness. Also, Kryptonite takes pride in its “Bent Foot Design” which is implied here.

You won’t get any cables with it, but it makes the lock lighter and simpler to operate. Just lock your tires with the frame or simply to another object. The thick steel resists scratches.

I found the ‘Bent Foot’ design to be helpful when locking my tires with the frame. This thing is really spacious! But you cannot lock two bikes with one lock using this one. There are two well-designed keys with the package too.

The Highlights

Kryptonite KryptoLok Series 2 LS U-Lock ReviewThe lock is pretty easy to use. Besides the main cylinder which lies at the bottom, you get the FlexFrame Bracket with it.

This bracket is available from 25mm to 80mm thickness. The standard size is U-Shaped as on Kryptonite Kryptolock Series 2 LS U-Lock.

But you can avail the oval, triangular or even square shaped lock if you choose. The lock is easily transportable thanks to the EZ Mount Transport mechanism. The positive of this system is, it won’t make a noise when you transport it. Furthermore, it can align itself with any type of frame or tire of bikes.

How does it protect Your Bike?

maxresdefault (1)The answer lies in how the lock is made. The cylinder at the bottom is a hard thing to cut. It resists almost everything. My house is near one of the busiest streets of Ney York, and I often leave my bike locked to a steel pole with it.

I can say from my experience that it resists cutters and even the drill machines that cut through most of the locks.

The Rating on Security Scale

Kryptonite is a brand which delivers the promise more often than not. To ensure their customers get what they bargained for, the company tests each product on their own scale. Kryptonite Kryptolok Series 2 LS U-Lock attains 8 out of 15 rating on the scale, and Silver Sold Secure Scale.

It is an excellent product to protect your bike from theft under normal circumstances. If you are a serious cyclist, this lock can be a bit under-par for you depending on your needs. It is a sturdy lock for those who have a budget.

Final Verdict

The Kryptonite locks carry a reputation with them. These locks signify craftsmanship and top-level security. Each of the products is meant for different bikes.

Kryptonite Kryptolok Series 2 LS U-Lock is intended for everyday bikes and not those which go through the heavy riding regime. Even then it provides top class security and proper support for its buyers.
