Kryptonite Evolution Mini-7 Bike U-Lock, 13mm Steel Shackle, 4 ft Cable | Sold Secure Gold Certified 13mm Hardened Steel Shackle, Double Deadbolt, FlexFrame-U Mounting Bracket and 3 Keys

First. We all need to understand. Any bike can be stolen no matter what bike lock you use. A bike lock is a deterrent. Like "hey steal the bike next to me, it does not have a lock it will be easy". That said this mini-7 is quite stout. Any thief will at least need to work a little, and carry the proper tools.This mini-7 was purchased for college student who would leave bike outside in a rack along with many many other bikes. So far so good.Its a safety/protection device. You cannot always put a price on safety/protection. However, I sure would be nicer if it was a bit less expensive.Pros:- great size- nice frame mount options- two keys included- optional theft insurance- pleasing color scheme- excellent build quality- reputable / trusted nameCons:- not clear/easy, cable storage on the frame- its small (duh its a mini, but be careful about buying this, it might be to small to lock both a wheel+frame to a solid support)- priceyWould I purchase again: YesWould I recommend to others: Yes

Great lock. Has both the cable and U-lock making it tougher for any thief. Easy to use. Happy with purchase.

(Revised)Had some trouble with the lock at first. Added some lubricant. Now works well. Had to jiggle it a bit but finally got it working.

I had my bike locked up for a few hours in the city. When I came back the u-lock had been cut through on one side, but my bike was still there! Because both sides of the u are locked in place, the thief couldn't take the lock off my bike even though he cut through one side. I still got lucky here that the thief didn't cut it a second time and steal my bike. Not sure if he ran out of battery or someone interrupted him.This is a good u lock that requires two cuts to steal, unfortunately with modern electric cutters a thief can do that in a few minutes. You need to spend at twice as much to get a lock that will last longer, and even then you are only buying a few more minutes that it will take to cut through the lock (maybe 8 minutes instead of 4)Everything else about the lock seemed pretty well designed. The frame mount works well and the keys turn smoothly in the lock.

Serious thieves use bolt cutters and cordless angle grinders that can cut through this lock in a minute, so consider this lock and cable combo suitable for only low-value bicycles of no interest to serious thieves. And that's why I bought it, for a low-value bicycle that I leave for short periods of time in low-risk locations. This lock will stop the casual thief without tools who might otherwise steal a low-value bike or wheel just sitting there easy to take. If you have a high-value bike, frequent high-risk locations, or leave your bike exposed overnight, then definitely get a better lock more able to defend against tools.Measured dimensions for the "U" part is 3-1/4" wide x 7-1/16" long (inside), and 4-1/2" wide x 8-5/8 long (outside). The cable is 4 ft. end-to-end, and 0.37" diameter with plastic cover. Before ordering this lock, be sure to measure dimensions on your bike and to what you intend to lock to so you're sure it will fit. The name is "Mini-7", less than regular size.I give it five stars for it's appropriate use for low-risk situations and low-value bikes, beyond that is expecting too much.

Awesome bike lock, easy to use

super easy, super strong, and the on-bike mounting bracket really works! But if you ever lock up to anything other than a skinny bike rack, get a lock bigger than the mini-7, it's a really tight fit.

It's easy to get into "analysis paralysis" when looking for bike locks on here. This one delivers on a few specific things I was looking for:1) You don't read too many reviews from people that bought a heavy duty lock, such as this, yet still got their bike stolen.2) I like that it comes with a cable. Even though I know it's only the U-Lock that truly protects the bike and that cables can easily be cut...wrapping it around your tires and other things thieves may want to steal provides that extra annoyance that can ward off those looking for a "quick grab".3) I like that the U-Lock can essentially be mounted anywhere on the bike. There are a few different locations they recommend mounting it, and having those options means you don't have to choose between mounting your bike lock or having a water bottle holder. You can finally have both.4) I like that it comes with 3 medium-duty keys that easily fit and turn inside the lock. I'm one of those people that will probably lose 1 or 2 keys of any set I am given, so this is great. Also, I never felt like I had to force the key to get it to turn (in fact, if you're forcing it you're probably doing it wrong).5) I like that the U-Lock buckles in on both sides, making it harder for someone to try and jam the lock off.All in all, if someone really wants to steal your bike, they will. But making it harder and more annoying for them to do so, and buying a heavy duty lock that will make their life difficult, significantly decreases the likelihood of that happening. I live in a medium-sized city (less than 1 million) where bike theft is very common and I feel comfortable leaving my bike locked up outside for hours with this one.

As a new bike user, I was a bit worried about choosing the right lock and took some time before deciding on this one. After using it for the past three months, I haven’t had a single issue. It’s super strong, looks great, and is easy to carry around. Feels very secure and well made ... definitely a great choice.

El tamaño es bueno para que encaje bajo el asiento de la bicicleta, de ser más largo no cabría en ninguna parte de mi bicicleta que es talla M. Se siente fuerte y seguro. El seguro contra robo que ofrece "Kryptonite" no aplica en mi país (México).

Super produkty

My first ever Kryptonite product and I am INLOVE. I've got 2 (race bike and a dutch bike) of my bikes stolen and 1 (mountain bike) destroyed to pulp, but with these locks nothing has happened to my new race bike so far.The frame mount is super nifty and cord gives me a lot of peace in my mind HAHAI have zero complaints!I've had a handful of moments where I was unable to open the lock due to its locking mechanism, but that's probably just a skill issue.And! Just a headsup, these are susceptible to rusting so remember to keep the keyhole closed ;)

Bon rapport qualité prix et possilite de l'accrocher plus facilement à un poteau
