    • Great bike chain
Color: Red Size: 32 Inch Style: Lock
Great! No thefts so far. It’s heavy but it’s no problem for me as I have a bag attached to my bike that I keep it in.

    • IT DOES ITS JOB.
Color: Red Size: 32 Inch Style: Lock
I purchased this to lock up one of my E-Scooters. It's shorter than I thought it would be so I'm limited as to where I can use it. You can't wrap it around a tree, that's for sure. It has some weight to it, but not super heavy. I use it along with a U lock, for double protection.

    • Great Locks--Even Superman Can't Break Them!
Color: Red Size: 32 Inch Style: Lock
What's not to love about these locks? Heavy duty design, but they are not too heavy to carry. The key is small and easy to use, and they are effective with any bike. These are designed for larger bikes; perhaps not ideal for young children. But aside from that, it's a great, highly visible theft deterrent. ... show more

    • I needed to get 2 for better length, but it's perfect now!!
Color: Gray Size: 32 Inch Style: Lock
After having my first Scooter stolen, that came with a huge wake up call regarding security & awareness of crime in general. I guess it took one loss to grab my attention. So, now that I know Cable locks are futile (as that was what I had on the Scooter that got stolen), I started my research. I ending up understanding I needed a GREAT chain lock & also a Ulock for backup. (But definitely 2 forms of security). So before I could order anything, a friend gave me a new mega chain. And I got a shackle U-lock for that with another top notch brand. And then I ordered one, then a second Krytonite Keeper for my second (backup) security. I ordered 2 because, even though this was the longest KK I could find (in it's class), it was still too short. I'd also always rather have extra room in a good chain, then have to worry about having enough room to lock it around whatever I might need to. The good news is, as solid as this item is for security, it is still only a few pounds. So even with the 2, on a 50CC Scooter, I am NOT weighed down, nor do I have less power on my bike. I should add. I use both the maga chain w/U-lock shakle & my Kryptonite(s) at all times when parked at home or parked anywhere for any length of time. And then for just running short errands or joy rides, I leave the chain at home & use my KKs only. This is a perfect system for me. I'm sure it exceeds the amount of security I need for the mildly low crime area I live in & yet is still convenient & easy to use!! ... show more
