Kryptonite Evolution Mini-7 13 mm U-Lock Bicycle Lock with FlexFrame-U Bracket & Bike Security Cable

Heavyweight and feels secure.

Absolutely the most heavy duty bicycle lock I have ever seen! The people at Kryptonite really put some thought into this lock. It has a convenient bracket that straps to your bike to haul this lock when not in use.(Bracket straps to bike frame and lock slides into bracket. Bracket has push button latch that must be released to remove and use the lock). It comes with a cable to loop thru your front wheel so no one can steal the wheel. It comes with 3 keys, 1 of which has a LED light to illuminate the key hole.(Key hole itself has a sliding cover that prevents debris from fouling or clogging). It comes with a $2500.00 reimbursement guarantee. They even have free key replacement if you lose all 3 keys that came with the lock. The lock itself is heavy. A thief would have a heck of a time cutting this monster. When I use this lock I don't have to worry about my bike not being there when I return! I would definitely recommend this system to anyone wanting a good, secure lock for their bike.

This is a great lock that anyone can use its not heavy and is very durable to with stand being dropped. We gave it to our daughter to use with her bike at school and she had no issues she said she liked it better than her old lock that had numbers that she had to memorize.

The lock is super secure and strong. The accessory cable is heavy and strong with plenty of length. The lock comes with 3 key duplicates. One key has a small blue flashlight built-in. The lock is easy to lock and unlock. And the lock is easy to attach to the included bike mount. And the bike mount is very easy to install onto the bike. I installed the mount in 3 different locations on the bike before I decided on the best position. All the components together weigh 3.5 pounds. Note: The bike mount only holds the lock. The accessory cable must be stored somewhere else on you or on your bike during a ride. I watched a youtube video (as recommended on the packaging) to get familiar with this lock and therefore I didn't even need to read the instruction booklet.

The bike lock is solid, feels well made and all however sometimes the key just gets stuck and wont go in where you need to try multiple times to get it in

Sturdy lock, high quality. Somewhat wish I would have bought the full size because at times the mini is too small to fit around the bike and rack. Also the key can be a pain to get in and out of the lock.

This is really an awesome bicycle lock. It has a real heavy-duty feel to it. There's even a small flashlight built into the key. The included cable is great if you want to add some security using a padlock. The only quirk is the key is a little finicky. It has to be seated just right to operate correctly. The lock can be mounted to the bicycle so you always have it with you.

I really like this lock but conditions have to be just right to use it. It is hard to find a suitable secure anchor base that is the right size to attach lock and a bicycle to. Now this would be the more secure way to protect bicycle. That said I think using included cable is very secure and gives you many options for a attachment point. I really like that it has 3 keys and one has a light. There will be many uses for this lock from power tools, sporting equipment, gates and my UTV. Quality lock. thomas

While this bike lock is certainly sturdy and would probably deter most bike thieves, it is *very* large. The suggested mounting locations of this lock work if you have a larger men's bike frame. However, my frame fits 5' 6” riders and therefore is smaller. I couldn't mount this on the inside of my frame without removing my water bottle holder. I'm returning for a regular chain as this simply doesn't work unless I sacrifice my water bottle holder.

I was really surprised at the size of this lock. I was expecting something 1/3 the size and Not so heavy. But if you want something very Sturdy, this would be perfect. I might use it to lock my trailer to a poll, I think that needs Something heavy like this. Comes with 3 keys and one of them has a light on it, which is kind of cool. Very heavy cable, which would take a lot for Someone to cut through.
