    • Heavy duty made to last
Pattern Name: Bike Security Cable Style: 7' (10mm)
Great quality, spent the money because no one was going to be able to get through this and it’s worth it. Long enough to lock all three of my bikes. Worth the cost

    • Long and Strong
Pattern Name: Bike Security Cable Style: 7' (10mm)
Perfect length and flexibility for locking up a couple bikes when coupled with a U-lock. For best security, use a u lock around both bikes or around the frame and wheel of a single bike then use the cable to attach to a fixed structure.

    • Serves it purpose - Buy a U-Lock for primary security!!!
Pattern Name: Bike Security Cable Style: 7' (10mm)
DO NOT USE AS YOUR PRIMARY MEANS OF LOCKING YOUR BIKE! Now that we got that disclaimer out of the way, onto the review. I use this to secure my front wheel, rear wheel, and bike seat to my bike U-lock (Abus Mini140). I use the same setup on my wife's bike This should be the only use for any nylon coated wire rope for securing your bike regardless of brand. PROS: +Good length to offer flexibility and allows me to easily secure the front wheel, rear wheel, and bike seat to my U-lock. We also use it to loop to our Burley trailer if we feel it is needed. +I felt the price was fair for the length and gauge. CONS: -None really, just know it's intended purpose. Also, take note that time and time again it has been proven that no flexible wire rope has proven to be better then any other. They are all easily defeated quickly with wire/bolt cutters. Look for the right length you need and a good price. ... show more

    • Nice cable, nice price. Not a floppy pre-coiled type, thicker/stronger/safer, easily trained to fit your preferred location.
Pattern Name: Bike Security Cable Style: 7' (10mm)
This is a really nice, well-made cable. I carry/use it with the U-lock on my bicycle. It's long enough to make it possible to secure all the stuff worth stealing on the bike, and still have enough left over to lock it to some sub-optimal things and places. It's heavy, the kind of heavy that comes with decent security. I wouldn't want something thin and wimpy that only keeps the honest people honest. Because it's kinda thick and heavy, not the floppy pre-coiled thing, this one needs a lilbit of 'training', but it easily wraps around my seatpost tight enough to suit me. I'm happy with this thing, it's a solid security product at a good price. As always, my usual top rating's four stars. I reserve the fifth star for those things that make me effusively, annoyingly happy. ... show more

    • I like it for quick lock ups in safe areas or accessories .
Pattern Name: Bike Security Cable Style: 7' (10mm)
This cable at 7 foot can lock up wheels , seat and frame quick when going in the local store or using a bathroom at a park only feet from your bike for just a few minutes. It is very light and easy to carry on these rides . No this is not security for a bike left unattended in a repeat location for any period of time . I do like it for times I must quickly have something available to lock the bike up in safe locations where I am nearby that are not part of my normal routine . Like using the bathroom in a bike park for less then ten minutes where you could hear someone . Using a motion alarm is a huge plus with it . Any more then that and you must break out the u lock too or bike chains rated at gold level . I now prefer them over the U locks because my new fat bikes have 5 inch tires on them the U bolt cannot go around one as their only 4 inches wide . Expect to pay $100 for a chain and still need a cable or 2 for accessories plus they are heavy , close to 15 pounds but if your leaving a bike in your garage or a rack at the apartment building unattended for long periods of time it is the best way to be sure it is as safe as possible . This is a very light cable that is suppose to be stronger than most due to being intertwined . A large set of bolt cutters could snap it . There are ways you can learn to wrap it so it is harder to get a set of cutters on it . I like it very much but only to keep honest people honest or where you can be back out and on the bike before a thief could react and get a set of cutters to take it . If I were to purchase again I would look for one about 5/8 of a inch which I noticed was on my other bike from another company with the same construction but this is so light I am ok with it for what I want to use it for . ... 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
