Kryptonite Evolution Mini-7 Bike U-Lock with Cable, Heavy Duty Anti-Theft Bicycle U Lock, 13mm Shackle and 10mm x4ft Length Security Cable with Mounting Bracket and Keys

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.

I use this lock all season in maine, the screw keeping the u lock from moving when stored can come loose but is easy to fix and the little cover for the keyhole keeps filth out of the lock, I have had other locks fill with road debris or straight up seize with rust and this lock still looks brand new after going through hell

highly recommend

So far it is holding up. We live in a generally safe area, where you can even see bikes without locks laying around. One is never too safe, so we still use ours.The lock mechanism came jammed upon arrival and we could not open it. We had to wiggle the key for a while until it finally gave in and were able to start using it. The lock mount attachment is kind of bad in my opinion. Only friction holds it to the bike, so naturally, it falls off and rotates to the sides very easily. You are better off just carrying the lock in a bag.

I have no complaints concerning the purchase of this bike lock. It took me a while to figure out where to mount the holder so it is out of my way but eventually found the perfect spot. Since I have a girl’s bike, I do not have the extra bar in the middle. This lock is easy to remove and I feel my bike is as secure as it can possibly be.

Mounted on the side of my bike because I had limited space elsewhere

Nice lock. Lube it good with dry lube before using. I had trouble turning the key in when I first used it, but after some lube and a lot of use it works great now.

Amazing lock, kept my bike for almost 2 years now on a busy campus. Worth the money
