Don't forget to regularly grease all keyholes and moving/connectible parts to stop the tealeaves from super gluing your Lock's!

​Judging by some of the reviews on Amazon, it does a good job of sticking on its own, no glue required!
Got two of these and never had any issues at all. Good solid locks and enough of a deterrent to the passing scrote with a pair of bolt cutters. I am sure it is like teaching grandma to suck eggs but if you do lock your bike up make sure the frame and back wheel are attached to something solid and the cable runs through the front wheel to the lock on the frame/back wheel. This lock is long enough to get through most frames and attach to something like a railing/post.
are they gold rated?
This is a great lock and after losing a bike in broad daylight at my office to a standard cable lock, I'd never look back. Downside is that it's quite chunky meaning that finding a place on your frame to fit the frame carry stand thingy for it it is near impossible. That coupled with the cable which again has nowhere to live when not in use means you'll end up lugging it in a ruck sack... otherwise I think this would put most would be scallywags off. Still less that an I paid... heat added.

It's silver rated which is the standard that the police recommend. But by all means go for gold if you want extra security for your bike.

It's a moderate security lock so third highest in the range. It looks a good deal but dunno if I'd trust it in a city centre for an hour or two, but for a cheaper bike, looks a fair option. Heat applied!

Personally I don't bother with the cable if I'm using the U lock. The U lock can secure the frame and one wheel as well.

This lock comes with a mount to attach the lock to the bike while you're riding. Based on my experience, unless you have a awkwardly shaped frame, you should be able to fit the mount onto the bike.

You can coil the cable up, put the loops in the lock and use Velcro to attach it at the loop end.

Mate, it's silver rated, literally what the police recommend. There's only one rating higher, and that's gold. I'd say silver is sufficient unless your bike costs close to a £1000 or more. Or if you park it in really dodgy places which in honesty if someone really wanted to steal or mess up your bike, they would find a way, gold standard lock or not.

It's very hard to recommend because ultimately someone can nick off with it whatever you reasonably do. I'd go for a gold standard and take care where it's left, securing it to a solid post where the bike can't be lifted from or which isn't weaker than the bike or lock. I'd also ideally use a gold standard front and back to secure wheels to frame and take the seat out. As I mentioned, the advertised one here looks a decent enough buy but not if you have a pricey bike and leave it 'exposed' in terms of time and/or location. I have a mid-range bike and use an Onguard Pitbull 8005 DT Bike Lock & Cable which is Gold Secure. Taken together it's only a little more than this one featured here ... if you check out the offer on Amazon it's £21.95.

Fair enough, but I don't have those. Quite frankly, if you're using the bike to commute and ride around town, you shouldn't get a bike with quick release wheels.

Could always get a gold rated one for not much more if you want.

I concur with the recommendation of the onguard locks. I have the onguard brute LS "long shank" it is sold secure gold rated and is often available on Amazon for around £22.

The same lock is said in Halfords with the magnum brand name on it for £70+!!

What a load of rubbish! What do you plan on doing if you get a flat tire whilst commuting?! Getting a spanner out and removing the wheel on the side of the road?

Great price. A squirt of graphite powder once in a blue moon keeps it going even when left outdoors permanently.

Yep, I agree with you on that...finding a good place for the lock where to sit can be like playing Tetris. The only suitable place I found on my back was at the back of the frame, but my frame is also weird shaped. I also need to think of a more suitable way to carry the cable.

*Touch wood*

I haven't had a flat tire for just over a year now since I've had my bike. I probably ride it 2-3 times every week. My bike is a hybrid, wheels at around 40mm. I imagine if you have a proper road bike with much thinner wheels running at much higher pressure, then you would be a lot susceptible to having a puncture, but surely it wouldn't occur often enough to make it worth having quick release wheels?

I always thought that in the rare event that suffering a puncture, you would just lock your bike up to a rack somewhere and catch a bus/train/taxi to whereever you need to go to. You could probably even carry the bike onto the bus or train. I certainly wouldn't think about constantly carrying a tool kit and be ready to do an on-the-spot maintenance job.
I bought mine 3 years ago in Amazon and it's a really good one. My byke it's been day/night on the street all the time. Recently I had to put some WD-40 on the lock, but makes sense after all the rain/snow/dirt for 3 years.
When registered online at kryptonite website I got a free 1year insurance, not sure if they still doing it with this model.

LOL. Had to laugh. I remember the days when most wheels were not quick release. No more difficult to use a couple of bike spanners to release a wheel than the quick release gubbins.

No, you simply use adequate locking.
I put the two ends of the cable into the lock and wear it over my shoulder like a bag. Works a treat.
Toastplex

In all my experience of cycling in and around town, your non-quick release wheels are not going to get stolen unless either:

a) they cost hundreds of pound each, I'm talking well over £200 for each wheel

b) you leave your bike somewhere public overnight, even then you'll be fine most of the time unless you leave it somewhere particularly dodgy or you leave it for over a week

Having to wrap the cable around the wheel is not worth the time and effort when you're just popping to the shops for an hour or two. You can use your U lock to secure one of the wheels anyway, leaving only one wheel 'exposed', but even then as I said, that's a small risk.
Best deterrent is to lock your bike next to one which has a flimsy lock.
I have a pretty crappy bike that I rarely use but need a lock. Could someone recommend me a cheaper lock than this? This one seems a bit overkill for me. Id like to spend around £5-10
