how does this work, where does it go (can someone take it out easily)? any pix in action ... i am guessing the battery provides the vibes with metal plates running along the bike's metal frame?

hmmm
can someone not design a van de graff generated alarm (dynamo driven) for this effect ...

I think you thread your lock through the metal bit at the back & any hard movement sets the alarm off.
Going to use it for my motorcycle in the back garden & think this is an amazing price, I guess you could use it for anything.

good price, heated up!
let us know how you get on.

the OH's motorbike almost got picked up by two men in a van a couple weeks ago – luckily a crazy neighbour shouted at them. the 600cc bike was tightly chained twice to a serious ground anchor too, but they would have had a big thing in their van to snap the chains off.

If the bastids want to tak eyour bike there's not that will stop them. You could always try the shotgun alarm. Tends to scare the pooh out of the non hardened crim. You might have some mjess to clear up afterwards though..
#8
So you bend the metal plates around the frame? After taking it off and putting it back on again (to change battery) won't that weaken that plate causing it to break off?

Looks good though, i was thinking of getting an alarm like this from ebay, this is a way better price though.

thanks worth a lunt me thinks...

It'll only take a hammer to shut this thing up. But most thieves will probably be starteled and run away
#11
How pointless, just like every other alarm that goes off, nobody is going to take a blind bit of notice of it.

All alarms achieve is making a lot of irritating noise mostly when the user forgets to switch it off !
#12
Beware, this is just a waste of money cuz this alarm is very easy to brake... don't even need a hammer, just a simple fist hit :P If you want to protect your bike, go for something more reliable. If you are able to spend 200 and more for your bike, you should go for something not less than this kind of lock - http://www.discountbicycles.co.uk/biz/product.php/4747/0/onguard_akita_premium_5035_belt_lock_100cm_x_25mm

These alarms are a deterrent to the opportunist thief, if some1 wants ya bike then they'll get it cus they'll have the tools. If something makes a noise to the opportunist it'll probably just startle them enough to keep them moving on. Its a good deal and I doubt any1 is saying this is going to be their only security device on a £5k bike. Obviously people that dim can be classed as a tax on stupidity.

Heat added.

I've yet to have a bad product from DX.

It is cheap, and the key looks mighty thin, but I guess to avoid getting it smacked with a hammer you need to mount it underneath somewhere, away from the weather but still so you can turn it on easy enough.

A similar product was the LIDL £7.99 disc lock alarm which works on the same principle but us made of steel.

used these things years ago. total pia. go off in breeze and whenever they feel like it. hoot to put in peoples beds who can't stand shrill noises tho!

You obviously haven't ordered much then. :)

But seriously - I haven't that much to complain about except the bicycle indicator/horn/brake light from them - the indicator LEDs were red!

This device you can assume will be far from waterproof and if left on a bicycle/motorbike parked outside will soon get water inside and fail.

Its going under a motorcycle cover for me anyway, its quite loud so good to scare away any chancers!
As I said its 2 squid so not going to be in the same league as a £200 system.
I use one of the torches they sell as my bike light with a bracket & this has been going strong for ages & is waterproof, a bit of kit like this would have cost me a fortune from a bike shop.
Will update the thread when I receive it for anyone waiting :thumbsup:

Funnily enough, a colleague ordered a bike light from DX (one with 70 or so LEDs) and the bracket broke at the first bump he went over. Luck of the draw I guess.

Unfortunately it isn't "Gold Secure" rated so not recognised by insurance companies if your bike gets nicked!

I completely agree, these are useless. They go off at anything, we had loads at the bike shop i worked in years ago and we binned them because they were not worth selling.

I wouldnt waste my money.

Maybe these aren't the same as the ones you were selling, besides these are just over two squid so if it explodes into a million pieces or grows wings & flies away I wont be heart broken :w00t:

Me too. But then, they sometimes cheat, and don't send things out.
