Wow this is amazing. This is the perfect size for my bike since I already have 4-pinhead locks around my bike all I needed is this u lock. Very simple and can fit in any bike pole and parking meter. I don't need to lock the tires or seat since I have that covered. With this you lock you will have a good night sleep. Trust me the bike right next to mine will get robbed, not this one, not with this heavy F$&@in brutally thick very thick small u-lock. My G@D this is F$&@in heavy. I will not complain with price because know I see why.

I believe this is the strongest bicycle lock Kryptonite makes. Kryptonite also makes excellent cables to go with it, such as the heavy-duty, braided Kryptoflex. Keep in mind that no lock, cable, or chain is unbreakable. You just want to make it extra difficult for the thieves, so they'll hopefully either give up or go after someone else's property. (Someone who skimped on their security by buying something cheaper.)

This is the very most secure u-lock on the market. One of the vulnerabilities of many locks is that savages can get leverage inside the lock using various methods to place stress and cause the lock to pop or yield. The NY-F addresses this by increasing the diameter of the steel material and shrinking the total size of the lock. You can read up on the history of the lock to learn more. Worth noting- it is important to take the time to learn how to lock your bike up properly. No lock will serve its purpose if you do not use it correctly. Also it is important to know that this lock may not work for you if your bike frame has large tubing. This lock works best for touring bikes and road bikes that feature smaller frame tube diameter.

I really think, It will take time for anyone who is trying to cut this lock. It gets five stars from me. The cost is wealth buying, because even if your bike is 300 USD, why let someone steal it. Let the bad guy move on to the next target. Don't feed his drug habit or let him get a real job.

Albeit it is a bit heavy, that's expected due to how thick and dense it is. I lock up my 2014 Ridley Fenix 105 with this, and I never worry about it. It's a great lock.

I had this lock for a while,but found it hard to secure to different immovable objects because of the size.....so I sold it on eBay and purchased it's hard to find bigger brother the Kryptonite M-18WL.....yes it is heavier 6 pounds if I'm not mistaken but I carry it in my back pack.... unless you bring a grinder,you will not be taking my bike.

Well, just bought it. Looks strong, until now, didn't have any experience with it, but I don't think it will be easy to break it.
