Really Impressed
This is a Very nice lock. Heavy cable, Nice big numbers (hey I'm old ). Setting your own code is super easy. The included bike attachment is very nice and easy to use. I suspect it will break long before the lock does.

Very stiff but secure
Looks good. Plenty of length. Good value. Excellent quality. I doubt anyone could cut through this cable OR the plastic covering so it is great for security. However, it is very very stiff and difficult for us to get it around the bike frame and then around the column to prevent from theft. It’s heavy and coiled into a circle which also makes it harder to get the post back into the mechanism to lock it. That’s the reason for 4 stars rather than 5. It would be perfect for a strong young person, but not easy for the over 60 gang. We certainly don’t worry that the bike could be stolen so that’s a huge plus.

Great bike lock
Great lock, a Master Lock product. Easy setting your own combo number. Comes with a mount that I attached to my seat post facing back. Cable clips into mount, pressing a button releases the lock, then lift out of mount, very secure while riding.

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.
