I did a bunch of research on which one of the Kryptonite and found the Kryptonite Evolution Mini-7 Bike U-Lock with Cable, Heavy Duty Anti-Theft Bicycle U Lock was the best fit for my bikes. It's easy to use, fits well on the mount and doesn't move when riding. The 13mm Hardened Max Performance Steel is more than enough to secure bicycles and the extra cable is perfect for securing the front tire as well.

Pros: Strong, secure, Anti-Theft Protection Offer; Up to $2,500 Reimbursement, Key Safe Program; Kryptonite will ship your first 2 keys for free, globally, in the event you lose them, holds in place in mount when riding, two keys included.

Cons: A bit pricey for a bicycle lock, but peace of mind isn't always inexpensive.

5.0 out of 5 stars Kryptonite locks are excellent
Reviewed in the United States on August 16, 2023

I have bought two of these bike locks. The bike did get stolen but it wasn’t the fault of the lock. The thief cut through the iron fence I had the bike locked to, and took the lock with them. So it’s definitely effective. My only complaint is that the lock mount that came with the lock didn’t include any instructions. So I wasn’t certain what that extra part was FOR. Until I saw a lock happily mounted to the bike when NOT in use. I thought the extra part was to prevent scratches when it was LOCKED up. So I threw the parts away…twice. Don’t be me.

5.0 out of 5 stars Solid, small lock great for small framed bike lock on college campus
Reviewed in the United States on December 23, 2023
Verified Purchase
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

4.0 out of 5 stars Good, but Could be Better
Reviewed in the United States on July 4, 2022

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.

pretty good lock so far, beware that sometimes the key will get a little jammed if its really humid outside. gotta tighten the bolt on the attachment to make sure it doesn't wiggle back and forth if you attach it to your bike so it stops rattling

5.0 out of 5 stars Great Lock, Using on eBike
Reviewed in the United States on April 20, 2024

This lock just fits between the frame and rear wheel of my ebike. I use the cable to wrap around the front wheel. I'm a bit of a Kryptonite fan and use their locks on all of my bicycles, but I'd always suggest backup security like registering your bike with the manufacturer, an organization for recovering stolen bikes and possibly installing a tracking device.

These feel super robust. The shackle is pretty small so it can be a little tricky to lock these anywhere, but with the wire the reach is not a problem though you lose a lot of safety.

Das Kryptonite Evolution Mini 7 Kabelschloss hat mich in vielerlei Hinsicht beeindruckt und bietet die ultimative Sicherheit für mein Fahrrad. Als passionierter Radfahrer ist es mir wichtig, mein Fahrrad vor Diebstahl zu schützen, und dieses Schloss erfüllt diese Aufgabe auf beeindruckende Weise.

Die kompakte Größe des Schlosses ist ein großer Pluspunkt. Es ist leicht und einfach zu transportieren, sodass es bequem in meine Tasche passt. Trotz seiner geringen Größe bietet es dennoch eine hohe Sicherheitsstufe.

Die Qualität der Konstruktion ist hervorragend. Das Schloss ist äußerst robust und widerstandsfähig gegenüber äußeren Einflüssen. Die schwarz-orange Farbkombination verleiht ihm ein auffälliges und zugleich stilvolles Aussehen.

Der Kryptoflex-Verschluss, der im Lieferumfang enthalten ist, ist eine großartige Ergänzung. Er ermöglicht es mir, das Schloss flexibel zu verwenden und mein Fahrrad sicher an verschiedenen Gegenständen zu befestigen.

Die Sicherheitsstufe des Evolution Mini 7 ist beeindruckend. Es ist mit einem 13 mm dicken Haken aus gehärtetem Max-Performance-Stahl ausgestattet, der Manipulationsversuchen standhält. Das Schloss ist auch gegen Aufbohren und Aufsägen geschützt.
