Kryptonite Evolution Mini-7 Bike U-Lock, 13mm Steel Shackle, 4 ft Cable

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.

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.

(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.

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.

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

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

Welp. Seven years after purchase, I’m back here to report that this cable and lock protected my bike from getting stolen! They tried cutting through the cable but gave up and stole my neighbors bike instead. Still going strong. Will be buying a replacement cable for sure.

Works as advertised

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.

頑丈で切断もされにくい

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 HAHA I 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 ;)
