  • Great for traveling with more than 2 bags
Pattern Name: Bike Security Cable Style: 2'6" (5mm)
Came back from vacation and used this to secure my luggage & bags when I stored them in the hotel. I had some important items and documents on me that I didn't want hotel staff rummaging through. Though I had stayed in a high end hotel, I've never trusted any staff with my belongings, as they all have access to all the rooms. Ties everything together securely with the addition of a sturdy lock. I looped it through the hand towel rack in the bathroom and had more trust in it than the "safe" in the room. I haven't tried it on my bicycle yet, and probably won't, as I feel like it's too thin and not strong enough against thieves and their cutters. Also, if you're traveling alone & staying in a cheap hotel/motel, you can also loop it around the door knob and something secured on the adjacent wall for an additional lock as you sleep. May not be as practical as a product specified for that task, but better than nothing. ... show more

  • It was the right size
Pattern Name: Bike Security Cable Style: 2'6" (5mm)
I bought this security cable to replace the larger steel cable (that was coiled for use on a bicycle). I needed a steel cale to securely attach the battery to my wife's lightweight and foldable mobility scooter. It worked perfectly. It is small enough to fit through the battery handle, but heavy enough that it can withstand anything short of bolt cutters. This is a very well made product for a good price if you don't need a large cable. ... show more

  • I would not trust this to protect my expensive bikes, but it's a solid short cable.
Pattern Name: Bike Security Cable Style: 2'6" (5mm)
It's exactly what it says: a short cable to add to a lock to secure something else. I use this in a place where I'm not too worried about getting my bike ripped off. Great for securing a wheel or a seat. Kinda thin for being a primary locking cable. Otherwise great.

  • Should have read the description better
Pattern Name: Bike Security Cable Style: 2'6" (5mm)
2.6' cable is thin, so not something I would use to secure a tire to the frame, but for something like a seat I would recommend one.

  • Good product, just too small

Way too small for an adult biker

  • Works really well as a helmet lock on a motorcycle
Pattern Name: Bike Security Cable Style: 2'6" (5mm)
Combined with a small combination padlock, this cable works well for securing a helmet to a motorcycle when I leave it unattended.

Pattern Name: Bike Security Cable Style: 2'6" (5mm)
The plastic looks worn and yellow, the little plastic covers on the ends of the loops have slips off and they look like they’ll break. But it’s still durable for it’s purpose, just looks shabby

  • Specialized Cable That's Great For Specific Uses.
Pattern Name: Bike Security Cable Style: 2'6" (5mm)
I have a heavy U-lock (Abus Granit Plus 640) that secures my bike frame and the rear wheel to a bike rack. I also have a quick-release seat. I pull this KryptoFlex 525 cable through the one of the stays on the bottom of the seat, then run one loop through the other loop, and then run the through loop down to the U-lock. This cable also narrow enough to fit through my helmet, so I don't have to carry it around. A second short, but heavier, cable is used in the same way to secure the quick release front wheel to the U-lock. Someone who with a good pair of wire cutters who knew what they were doing could probably go through this KryptoFlex 525 in a few minutes, but to get a used helmet and seat? This deters crimes of opportunity, not a professional thief; realize what you're purchasing. The KryptoFlex 525 is small and light weight and also used with the second short cable to suspend the U-lock between the seat stays and the rear bike rack while I'm riding, too, eliminating the need to carry the U-lock with brackets on the down tube. In short, it's perfect for what I need. ... show more
