KryptoniteEvolution 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

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

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

This lock has to be locked and unlocked a very particular way. It was tedious for me. I lost the keys so I have to order new keys. It seems very sturdy. I would still strongly recommend it for enhanced bike security. Tedious to put in place and tedious to remove.

Compared to most other less expensive locks that I've had, this Kryptonite Evolution appears to be better crafted, has a much heavier crossbar, the cylinder engages the shackle at both ends, the keying system feels more like a real lock, and it seems to be robust. Overall, these are impressive qualities that I do appreciate and they make me feel better about locking in high crime areas. However, there are some issues: the 13mm shackle is really not much heavier than most other locks, the shackle is a little too short for many real-world applications, the keying is sticky, and the bracket mount needs improvement. For a lock at this price, these issues are a little disappointing. I guess I can live with the 13mm shackle with the understanding that it's a trade-off for lighter carrying weight. The shorter shackle is a bigger issue. Another inch would make it so much easier to lock in many situations. The keying can be frustrating to engage, but maybe it's just the individual lock that I purchased. The thing that I dislike most is the bracket mount. It's complicated to install. Once installed it's even harder to reinstall in a different location if you need to after you've trimmed the band. The bracket's bulky shape just doesn't look that great when mounted. Also on the issue of aesthetics. the color of the lock itself is a brighter orange than it looks to be on most web photos. Perhaps this was a marketing decision for brand identity. A more neutral color would look so much better on most bikes.

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.

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.

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.

Very convenient. Very easier to lock. I use this for my REI COOP eBike for commute work.
