Great bike lock!
Great bike lock! My brother and sister-in-law have the same lock and recommended it to me. It’s very rugged and well-made, and I like the combination feature. I feel safe in the fact that it’s so well-made and have no fear of someone trying to cut through this and stealing my bike! And for the price, it’s outstanding!

Great Product That Gets the Job Done!
The Master Lock Cable Lock, 6 ft. (8122D) is an overall great product. The 6-foot cable provides plenty of length to secure bikes or other items, and the set-your-own combination feature is super convenient—no need to worry about losing keys! It feels very sturdy and reliable, giving me peace of mind when I lock up my bike. One thing to note is that it’s a bit bulky, which might make it less convenient to carry around on longer rides. However, the extra thickness also adds to the sense of security. If you're looking for a dependable bike lock that’s easy to use and offers solid protection, this is a great choice!

Easy to use, affordable bike lock
Came exactly as advertised. Very convenient where you store the cable on your bike. The combination is easy to use and easy to reset the unlock code. I was worried it might be bulky and hard to use because its circular but its not. The speed or easy of disengaging it from the bike and then using it was very easy. With the affordable price and easy of use, i recommend this product.

Can’t Be Easily Cut
Unfortunately it’s a really good lock as it’s not easily cut. Would be very difficult to steal anything it locks up… However when it fails to open that’s not helpful! Bought this for my daughter to use while in Atlanta. Right away, we changed the code so she would be able to remember one she established. You attest the side dial and set the new code. We did that and tested the new code several times before locking up her bike. The next day I put the lock together and locked up her bike. She was able to unlock it herself and rode to a local Target. When she arrived, she called me and asked if I had difficulty putting the lock back together when I used it, I said no, although it was a bit “stiff”. I told her to push it together and that should be fine. She did eventually, locked the bike, and went into the store. When she came out, she could not open the lock. She tried several times and it would not unlock despite having unlocked for me, and for her. She asked for help, tried lubricating it (since it was stiff), and nothing would work. The lock would not open. She asked for help from Target employees and security. Even though they could not get it open. They tried cutting it with typical bolt cutters and it could not be cut. It took a locksmith to open it and they used specialized cutting tools. So while this is a great lock that is not easily cut, I am having a hard time giving it more than one star because she used it three times before it wouldn’t open. It’s being returned.

Just a bit annoying SOMETIMES
it comes with a clip to attach to your bike which is nice. just that it's so stiff and wound up that it CAN be annoying to lock your bike sometimes, but not too big of a deal. setting your code takes like 30 seconds too. if you feel that it's hard to open the numbers have to be closely aligned.

I had my bike locked using this product and someone was able to cut through and steal the bike. I wouldn't recommend this product. My bike was at a train station so the perpetrator would have to be relatively quick. I'll have to go with another option maybe a chain.

Don't why it has to be this long, but it coils up nicely, and it's easy to hang anywhere on the bike. Nice tumbler lock. Dam tough.
