What is it?
A Kryptonite D-Lock and a short cable flex to lock up your bike,

What's good about it?
* Incredibly Sturdy: The D-Link lock is remarkably sturdy, and it should protect your bike from all but the most persistent thief. I note from another reviewer, it took 15 minutes cutting with a diamond tipped angle grinder to open (they'd had the keys stolen).
* Pretty solid cable: The addition of the cable is a great asset which means you can loop round a wheel. Be aware, some thieves will steal a quick release wheel on an expensive bike
* Includes Insurance: Kryptonite will refund up to 800 if your bike is stolen (but see the "cons" below for the small print)
* Great Price: Lets face it - if you've spent on a bike - it's worth spending the extra to ensure it's not stolen

What's not so good?
* Mounting is a pain: I eventually gave up trying to attach the D-Lock to the bike, and now I simply carry it in a back-pack. In my view the plastic housing which is fixed to your bike, and enables you to clip the D-lock to it to carry around is INCREDIBLY BADLY DESIGNED.
* It's heavy. OK - so this is a good and a bad thing. Good because it adds strength. But think of carrying an additional two bags of sugar around with you. (1.6Kg). Hence I carry it in a back-pack
* Cable is short: The research advises placing a cable to include your front and rear wheel, and this is just too short. It does however add an additional feature - which included in the price is good.

4.0 out of 5 stars Solid so far! 26 Aug 2012
Verified Purchase

- The company will refund the cost of the bike (up to 800) if you register your lock and your bike with them on their website if your bike is stolen.
- Lock feels substantial and will certainly deter the opportunist thief.
- Solid cable, which ensures more complete protection for the bike, allowing you to tie in the front wheel too.
- Affordable - well-priced for the protection it offers.


- Lock/cable is fairly heavy to carry around.
- Key lock can be a bit fiddly to operate: I worry a little that in the future this could lead to difficulties with being able to unlock it but it will probably be fine!

4.0 out of 5 stars Good lock, lousy attachment system 28 Dec 2013
Verified Purchase
In the year I've owned this lock it's been very reliable. My bike hasn't been stolen yet (unlike my last one with a mid-price Halfords lock) and the key doesn't jam in the lock like it can with cheaper locks. I do have to say my bike is stored in a locked biked shed at night and undercover at work so the lock hasn't been exposed to the full range of elements yet. What does let the whole package down is the method of attaching the lock to your bike. A fabric strap is soaked and pulled tight around the frame and held in place with the clip. The idea is that as the strap dries it will shrink and tighten even more. The problem comes as the clip is very tight and it can be a struggle to remove the lock from it (especially when it's raining!). Over a few months this constant shimmying works the fabric strap loose until the lock starts flapping around when you cycle requiring the installation to be repeated.

5.0 out of 5 stars Great product 9 Aug 2013
I used this lock to take my mountain bike all over the place, and I have evidence that it does the job.

My bag got stolen, which had my bike locks keys in it. Due to this, my bike was locked up in a dodgy part of town, and I had no way of retrieving my bike other than cutting it lose.

Tools we used: Fireman bolt cutters, handsaw, a van, a saw.

All of those failed. The bolt cutters left about an impressive mark on it as a toddler would if it chewed it. The handsaw did nothing, the van did nothing, the saw did nothing.

In the end we had to use a mains powered angle grinder and a diamond level saw disk, even then it took a good 15 minutes and the diamond level saw disk was in complete tatters, and had to be thrown away.

Not bad for 20. Although the difficulty was with the MAIN LOCK. The extra CABLE came off pretty easily.

1.0 out of 5 stars I would not recommend this! 1 Feb 2014

I thought it would be useful to write a review, having purchased this around 5 months ago and used it regularly.

This lock has become more and more stiff with use, and it has now got to the point where every time I lock my bike up I wonder if I'll be able to unlock it ever again. My friends and I all have this lock, as it is a very popular one, and the same thing has happened to them. It seemed fine for the first few months of usage but now when I put the key in, I can turn it to about half way and then it jams, and I really have to jiggle it around (more and more every time, and very vigourously) to actually get the lock undone. Sometimes I can be there for a good 5 minutes trying to get it undone, to the point where I almost give up and walk home! Several of my friends have had to buy new locks because of this problem and I will also be buying a new one.

I am not sure if this has happened due to something we have done to it, but I always cover the keyhole up and I have also tried oiling it, neither of which have seemed to prevent this from happening. This is a shame because the lock looks great and it is very sturdy with a lot of promise.

I hope that this will be helpful to bear in mind, even if you do still decide to buy it. All I'm saying is that I know a lot of people that the same thing has happened to, which doesn't seem like a coincidence.
