Locks that work

I want!
I noticed that there are many similar looking locks at a similar price - Does this one stand out form the others? I see that this one has an 'intelligent sensor' which doesn't go off if you want to unlock it.

Well i haven't tried any others, But i was looking at this one:
http://www.kabrus.co.uk/xl202.html

It's labelled as a "bicycle lock", it seems to have the same mechanism and electronics, but it looks a bit exposed to me.

as Sherms; the shackle isn't symmetrical. If you put it in one way, it will engage the alarm, the other way is a plain old padlock.

Perfect, make sense now, will put a little tippex on the alarm side so I know which side to put on.

Its supposed to be 18mm, but I'd trust the Parker International version rather than the Amazon sale. They're some fake Kryptonites on the market, and I think I'd steer clear of something that just looks wrong.

Someone on here bought what I feel is a fake Kryptonite chain, and its probably not such an isolated incident. Buyer beware.

A lot of people get confused with the M18 as it's so similar in appearance to the 16mm NY. It's actually classed by Kryptonite as a powersports product (i.e. motorbike lock) so you won't find it listed under bicycle category locks on their website...

Madison (UK Krypto dist.) have been bringing it in and selling successfully in the bicycle market for a good few years as it gives gives more room to maneuver than the 18mm Fahg. Bloody heavy mind!

Hope this helps.

I've had one of these for 3/4 months now, (you can get t with a slightly longer shackle which manages a tyre+seatstay) it does work great but it seems to use up juice even when unalarmed?!?!? i seem to replace the batteries every 6 weeks regardless whether i use it much or not. no warning if they're running out neither, activation beep goes off but not enough power for the sensor to be armed/alarm to go off.( replaced the batteries end of sept, just demonstrated to a friend and nothing happened... off to the pound shop....)

Purchased one of these off the bay, £15.
It beeps once when armed, it will also emit three warning beeps when first tampered with.
After that, it will be highly sensitive for 30 seconds, during which, breathing on the bike will sound the alarm.
It's pretty small and solid, fits on virtually any part of the bike bar maybe the rim.
Waterproof, good keys, batteries supplied for 3 years.

Been using it for a month or so along with a evo mini.. Could not recommend it more. Popping into the shops or the pub with this on the chainring gives me complete peace of mind.

It has been set off once, and the kid shat himself. I almost want to encourage someone to try and steal it just so i can run outside and crowbar them.

Get one.

No such problem yet, maybe the cold sucks them dry?

I don't really lock my bike up for more than an hour or two. I imagine it wouldn't be too suitable for all night regular locking if it runs out that fast..

Did yours not come with extra batteries? Orr did you use them all up already? That is concerning, since they're labelled to last 2 years!

Perhaps contact Kabrus about it. I'm sure if you mention that you're on the forum and the potential of the lock in the market, they will jump to help.

good call. yep i used the spares already! i have to say I don't think i've left it locked for more than 15mins at a time, and probably only set it the alarm way round a dozen times that's why i was wondering how it chewed the batteries so quick?! will msg them now.

also seems less sensitive now...?!?

i wonder why they use multiple button cells as opposed to regular batteries?

I'm confused with the M18 - are their multiple versions of it? Some claim 16mm and others 18mm.
Amazon link below to "16mm version"

The description further down says it's 18mm, as it should, the 16mm equivalent is the New York 3000.

Loved it;

That is excellent.^^^^^^^^^^

grp: too heavy for couriering? if so, what would you recommend sub £30?

If its daytime work, and you're only leaving the bike to pick up and drop packages, then a good thick armoured cable lock is the answer (not recommended for any other purpose other than courier use, and leaving for only unattended for only a minute or two). Wear it around your waist, if you're slim (and you are), and then have a serious lock for when you're at the pub and leaving the bike unattended for hours.

Interestingly, you've raised a very valid point - the weight of locks.

I shall amend the list and add all the lock weights that I can find, so people can make a choice based on that as an extra variable.

Josh, alarm lock FTW, combine with the Evo Mini, should defintely keep thief off your back.

iam not putting 2 locks for 30 seconds

Got a magnum gold sold secure job from Halfords, still rocking after 4 years.

I'm lucky though, got a "reserved" bike stand at work which I leave the lock on. It is fairly hefty but i trust it completely.

I've now added all the weights I could find for the U-Locks. I won't put the weights for the small alarm locks, or the big, heavy chains.
There would be little point for either. .

probably shouldn't wear locks around your waist, if you fall they can brake ribs etc or so i've read on another cycling forum

Abus

Had a search but couldn't find this mentioned yet:

http://www.lockyourbike.org.uk/

Probably not much that couldn't be gleaned from threads on here but probably a useful one-stop guide. London-centric as well. (Wasn't sure if it belongs here or "how to lock your bike" but this seems to be the best reference thread.)

Any news on this? Does it use the batteries really fast? If not I might get one.

This was my first bike lock, it served its purpose
I've since upgraded, got it for cheap too.

^ both of those are utter shit locks.

buy a better one, or you will lose your bike in London.

Any thoughts on the mangnum locks? Gold rated apparently.
