Crazefoto Security Lock Self Coiling Resettable Combination Cable Lock, Bike Cable Lock, 4-Foot x 1/2 Inch, Theft-Protection Lock, Flexible Lock with Mounting Bracket

Very cheap lock mechanism. No instructions on how to set the combination but they are here on Amazon. I set the combo - tested, it worked. I took it on a ride but when I tried to lock the bike it wouldn't lock. When I got it home I fiddled with it and finally got it locked. Now it won't unlock. Returned.

Horrible lock! First instance, rode my bike to the barbershop, lock it up and come back to find it moved to another spot. I turn around and this guy weed whacking says "is that your bike" i say yes, then he tells me is "####" your combo, i was like yes, then he tells me your lock sucks get another lock. Second instance, i ride my bike to college, lock it up on the train station bike rack and never saw my bike again (see pictures below). HOW BAD DOES A BIKE LOCK HAVE TO BE TO BE BROKEN IN BROAD DAY LIGHT IN FRONT OF A TRAIN STATION!!!

I'm not one for hyperbole, but this lock is garbage, and if you buy it, you're just throwing away money.The FIRST TIME I used this lock, I had a hard time getting it to close and lock. In the process, I'm guessing I inadvertently reset the combination, because I couldn't get it open, and had to call the Sheriff's Department for help.Chances are, you've researched bike locks, and everything you've read screams to stay away from cable locks. Let me tell you, it was more than disconcerting to watch the Sheriff cut through the cable in 7 seconds.Save the $10 and invest in an expensive, quality lock.

It's the worst bike lock I've ever used ,just worked for 3days after that I couldn't open the lock where I locked my bike .never buy ,too much headache if you have the same problem like me .doesn't worth one star but star rating is required, I don't want to give it a star

I like the way I can hang it on my road bike. That alone makes it better than the others I considered.I really loved this lock - until it broke. The clamp was the problem. The screw that is used to tighten the clamp pulled through the plastic. Now the clamp (which is the best feature) is useless. I'n thinking that I can fix it. We'll see.In the meantime don't tighten the screw too much.I have to change my review. The clamp has continued to be a problem. I fixed it the first time. This time it's unrepairable. Other than that it's a decent product at a low price. It's a shame the bracket breaks because I like the mounting system. They need to think about the type of plastic they're using.

The cable is strong and well designed. The company sent me a new replacement bracket that is now strong enough to hold the cable (see the before and after images below to see the difference).Here is the background story: The original bracket broke around the screw area after a couple of weeks of use. It was too weak for this cable. The representative of the manufacturer in China contacted me by phone and asked if she could send me a stronger bracket. I agreed, and she kept her promise. The replacement bracket is much stronger. It is the bracket they used exclusively on their 5 foot cable package. They assured me that this stronger bracket is now also being shipped with the new 4 foot cables as well. So now I have changed the rating for this lock system to 5 stars.Since receiving the original cable, we've used the cable on bike trips to lock two bikes at the same time. In my opinion, this combination system is much better than using a key lock. We lose keys like crazy - so this solves that problem. Plus, this combination system is very easy to use. The cable always coils into a small volume - so if you don't want to put it on the bike - just throw it in your backpack.The bracket comes with a rubber pad that lines the inside. The pad size can trimmed to down to allow the bracket to fit on different tube diameters. For the seat tube (not the post) on my Trek, I had to cut the pad in a little less than half length to get the bracket to close properly. For the seat post, I would have probably needed to use the whole pad. The pad provides the adjustment necessary to get thes cable bracket to fit in multiple places around the bike.The cable comes with instructions. Setting the combination is very easy. Put the combination to 0000, pull the cable apart, rotate the set knob 90 degrees clockwise until it clicks, set the combination, turn the set knob 90 degrees counter-clockwise until it clicks - and the combination is complete.I highly recommend this cable lock.

First of all, if you take the security of your bike seriously, this type of lock needs to be a secondary lock. I don't think I'm allowed to provide links in an Amazon review, but if you Google about, there are numerous articles online about how to properly secure your bike to best reduce the risk of bike and part theft. And yes -- reduce. There isn't a lock in the world that'll completely prevent theft. If you make your bike the least appealing target, around, however, you're ahead of the game. So, for my partner's not-really-expensive bike, we have a U-lock, locking skewers, and a couple of cable locks. The bike's rather new, so we're still working out the best combination of security and not carrying around 900 pounds of said security. We live in New York City, where bike theft is really common.About this lock:The numbers click into place, which is nice -- it means it's harder to accidentally move them while manipulating the lock, so you don't have to redo the combination once you're ready to lock it. Also, the wire part isn't as stiff as our first one, so its easier to unroll. The only drawback about this particular length is that you really can't lock up much other than a wheel. Also, the lock is too thick to go under her seat so she can't secure the seat with it.This is a really decent secondary bike lock, especially for the price. We got one free for review -- and will continue to use it.
