Kryptonite Keeper Mini-Bike Lock, Heavy Duty Anti-Theft U Lock with 12mm Harden Steel Shackle, Mounting Bracket and 2 Keys for Bike, Motorcycle, Scooter, Door, Gate, Fence

I like the key idea and the strength of the lock.

I specifically enjoy this brand due to quality.My only issue is I didnt read and this is apparently not a big enough lock for my mountain bike xDI can lock the wheel to the frame? But that's about it. But it is a good lock nonetheless :3

I feel safe with this lock, so it does its most important job. However, when it comes to usability, it can be quite difficult to turn the key to lock and unlock—it sometimes requires a lot of force, twists and turns. I may need to replace it at some point, as it could be a defect in my specific unit. Bottom line: good but not perfect.

A bit of a wiggle on the attachment that secures the lock to the bike frame, but otherwise a good product for it’s intended purpose.

Great lock, easy to use. Can someone come with a battery operated sawzall or cut off saw to cut this lock off in 15 seconds? Of course they can. The same way they can cut through the $100 kryptonite fuhgeddaboudit lock (so why spend more?)I use this to lock my electric scooter when I go into a store for a few minutes or when I'm in the gym (I lock it inside the gym next to the front desk).Remember, locks only deter lazy theives. If someone wants your bike they are going to take it.

Love the construction of this lock. I would buy this again.

This a solid product. It’s well made, compact and looks good.

My husband and I both got this lock. We were concerned about the multiple reviews complaining about the lock jamming, but we figured people were unnecessarily whining. Both of us have had issues with jamming but messing for a minute or so with a slight wiggle usually fixes it. We assumed that's what these reviews were about.Today I COULD NOT lock my bike because of the jamming issue. I tried for somewhere near 15 minutes. I tried messing with the lock not around the bike and I still couldn't get it to lock. I ended up having to bring my bike inside my office, which thankfully that was an option for me. I waited and tried again in the afternoon with the lock inside. After about 10 minutes of messing with it I was able to get it locked again.My husband has never had an issue this bad, but I used my lock daily.Perhaps the cold was the issue. Either way, a "lock" that doesn't lock is garbage. Save yourself a headache and buy a different one.

Molto piccolo e leggero, usabile molto poco a causa delle dimensioni super mini

Solide et discret. Il n’est pas trop lourd comparé à d’autres modèles

Habe mir das Schloss für meinen E-Roller vor 2 Jahren gekauft. Die Qualität des Schlosses ist super und ist auch nach Jahren funktionstüchtig. Der Schlüssel ist ab und zu etwas schwergängig, aber hat bisher ebenfalls immer funktioniert.

Perfect for keeping my bike safe

Nice Ulock. The small size coupled with a braided steel cable works well to secure 1 or two bikes.
