Solid, small lock great for small framed bike lock on college campus

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 name Cons: - 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) - pricey Would I purchase again: Yes Would I recommend to others: Yes Read more

Great deterrent

Good quality lock and cable. Thief’s with machine grinders will steal your bike anyways so this is just a deterrent from easily taking your bike away. ( say in front of school or somewhere that is inherently safe but you want to have a deterrent anyway ). Read more

Good lock. Follow kryptonite instructions for the mount!

Great lock kit. Reviews say this is good against just about everything but a very highly skilled locksmith or an angle grinder. Some reviews state that the mount is flimsy. However, if you follow the directions and watch the kryptonite video on YouTube, install the mount correctly, and tighten it down really well, it's nice and secure. Read more

Great lock, with a few annoying issues.

This is a solid bike lock and I really like it. The thing is as sturdy as a Mac truck. Although, if someone really want to compromise it they will. No lock is perfect. However, there are a couple issues that I would like to address. The first of which resides with the bike mount. It is a complex two component rig made of soft plastic that peels away when you try to tighten it down. It never worked on any part of my bike frame. The plastic on the bottom of the mount just peeled away as I tightened it. My wife purchased a cheaper knock off of this lock that has a simple frame mount that makes sense. It uses a two piece design that wraps around the frame and locks it in place with a simple screw. It actually tightens itself onto the frame. The one for this lock is......a frame mount for a lock mount that is mounted on the frame mount. It is absolutely ridiculous and kind of sad for such a high priced lock. The other problem is that the lock is way too big to be mounted on most of the bike frames on the market. I don't think that can be helped though. My bike has a thick frame and the lock barely fits through it on most bike racks around town. We have to carry our locks in our backpacks. Not a big issue, just an annoyance. The last thing is that the lock can be picked very very easily, which means that the core is a simple straight pin lock. So if anyone knows how to pick locks, then you can kiss your bike goodbye. Again, no lock is perfect and if a thief wants your bike, they are going to find away around every lock that they come up against. Regardless of these slight issues, I would rather have this lock than a cheaper model. Read more

Worth Every Penny

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. Read more

High Quality but tricky

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. Read more

2021 version never worked and Kryptonite would not help with it

Expensive lock that never worked, and Kryptonite would not help me with it at all. The pieces in the bar with the key don't shift when the key is turned. It was sticky and difficult upon purchase, but all Kryptonite would tell me is to try to lubricate it. I'm glad I stopped using it because I would have had to have it cut off my bike - the thing doesn't budge. Lubricating it does nothing. I clearly got a faulty one and Kryptonite refused to do anything about it. Anyone know where to recycle these things? Read more
