KryptoniteKryptoFlex Security Cable, 2.6FT/4FT/7FT/30FT Long Braided Steel Flex Bike Lock Anti-Theft Cable with Looped Ends for Outdoor Equipment, U-Lock and Padlock, 5mm-10mm Thick

This is meant to be the best quality 1cm security flex that you can buy, and as this hasn't been tested as yet, I have no reason to disbelieve it. It certainly looks the business & is good value for money & is perfect for locking front wheels & removable seats to an existing lock.Having said that, (and I apologise here in advance if the following advice is teaching grandma's to suck eggs...):I do urge people looking for security for their bike to understand that any thief worth his salt can still get through this cable with just decent quality snips in only a very short time.You therefore need to anchor the bike to an immovable (eg steel post) object via a decent heavy duty lock & chain or shackle lock (google "Sheldon Brown" online, but preferably secure through rear wheel & frame together if possible). Try not to leave room for a thief to get a small "bottle" jack in the "D" of a shackle lock if using this mode of security (try to buy the shackle that fits your bike snugly & just has room for a post).I suggest that for evey £10 you spend on bike, you spend at least £1 on lock... (and start at no less than £20).The Sold Secure Silver Kryptonite Kryptolok is a decentish sub £25 shackle for anything up to around £200 new, for example. Their Evolution lock is just a few quid more and is Sold Secure Gold (see my other review, as I have one).Please however remember that if a thief good at what he does wants your bike, he will have it... The trick (unfortunately for others) is to move up the ladder by getting him to move onto easier pickings.Other tips:1) Lock bike outside cafe's, pubs, places here plenty of people are visible just inside (the thief does not wish to be disturbed by an irrate owner/punter).2) Park where monitored by CCTV (although most thieves would not be massively deterred)3) Make sure the post/fixing you attach to does not allow your bike to be simply lifted up & over it!4) The item you attach your lock to must not be construed to be actually much weaker than your lock (although attaching to anything immovable offers another layer of security).5) A good independant reviewer of all bike locks (attack tested independantly) is "Bike Radar" (just google it). Be wary, as the odd sold secure gold lock does not rate particularly well in their practical testing.I hope thats of help to some (sorry if you read that lot & knew it already)...

Having all or part of a bike stolen is heartbreaking. Even when the one stolen is as cheap as chips. Take it from experience. Anything that can help is worth its weight in gold and this is a device that will get your average bike thief to move on to one that doesn't involve quite as much work. Unless, naturally, your bike is a Rolls Royce. Then all bets are off!For those that don't know, this fits in various ways. Through the seat if you want, but in my case through both wheels and around a solid D lock and through a cheaper cable lock too. In other words, stops either wheel being taken. However - to be clear - if the main lock is broken this is broken too.Don't cheat yourself on length. Shorter might leave you struggling. This will - in my case anyway - warp around the seat pole and could even be used to secure shopping to the front handlebars. The advantage of a sturdy bike.No complaints at all - should be standard issue in today's world.

Nice and strong. Easy to use with a d-lock. Quick delivery. Good quality thanks james

It’s a good solid cable. I use two of these cables through two u locks to secure 4 bikes together. Feels safe enough to leave. The biggest deterrent is having dirty old bikes that no one wants, and I didn’t want the cables and locks to be worth more than my bike.It’s flexible enough to weave around the bikes, one loop end can go through the other loop to maximise the length of the cable.I know if the bad guys are well equipped they can cut through most things so making it difficult is a deterrent.What worries me about the cables is that with a pair of bolt cutters you can cut right through them so I put one cable through all main frames and through a ulock around a main frame and the railing or bike stands then run the other cable through the frame near the front wheels and through the first ulock and put the second ulock through both cables the first ulock and the railing so there are two points to break.I also use these to secure my tow bar bike rack to the van using the cable to wrap around the chassis, the bike rack and the tow bar.I’m pleased with the cables, the sheathing is a good flexible hardened plastic and I’ve used them and abused them for a few weeks and with a quick wipe they still look good as new.

Feels secure when looped through my front bike wheels. Was a little more expensive than I expected but worth it as a deterrent.

This is surprisingly light, for it's strength. I feel much safer now locking up my big new bike 🤞🏻🍀

I am using this with a kryptonite Faghettaboudit mini lock, and it seems good quality and doesn't look easy to cut through being steel. I hook it around the front wheel and through my seat then lock the hoop onto the D lock on my back wheel which is always locked through the frame and wheel to the bike rack, any other type of locking isn't good enough in my opinion and is a guaranteed theft attempt, they only try and steal badly locked bikes usually.The only downside is it takes longer than you might think so make sure you are there 5 minutes earlier, (especially at train stations with 2 minutes to spare) lol. Having my bike almost stolen the other week has changed my attitude to locking it up and I now lock it properly everywhere I go. do NOT use combination locks, they don't really do anything and are very easy to cut through, this was my wake up call, and my bike is expensive so it needs to be secure.Obviously thieves can snap through most cable locks but if you have more than one lock they probably won't bother. I've not had this long so we'll see how it lasts and hope they leave my bike alone.I Hope this review helps someone from having their bike stolen!

This is my second Kryptonite cable as I was that pleased with the first one. Unfortunately until someone tries to steal the items tethered with the cables I don’t know quite how good they actually are!
