Bike lock with siren

We are thinking of getting a bike lock with an alarm. There are lots of different types out there and just wondering if anybody has used these. The idea is that it would be in addition to other locks but has the advantage of making a loud noise if anybody tries to steal bikes which would wake us and also act as a deterrent. Something like this seems good http://store.lockalarm.com/about/

Have a look at lockpickinglawer's Youtube channel. He tests a lot of cycle / motorcycle locks, not only picking them open but using the tactics a thief would use to get the lock off.
The 'Litelock' for instance, which is - according to various youtube videos - undefeatable, he got through in 16 seconds.

Might help you make up your mind.

BTW I have one of these http://tiny.cc/jm8c1y for the motorbike. The alarm is mildly irritating and not at all loud.

Don't buy one of  THESE

Better, if you are using this when your bikes are on a bike rack, would be a cheap rape / personal alarm. 

Tie one end of the cord to the bike and the other end to the bike rack with the alarm in the middle. When the bikes are removed the peg pulls out of the alarm and you have a truly vomit- inducing and long lasting very loud siren. It won’t stop until the peg is re- inserted and that is not easy to do in the dark or in a panic. Certainly wakes the neighbours !

Now that's a good idea. Just can't tell which ones have a button to set them off and which have the peg. I've sent some messages to sellers. Thanks.

Hi, I had a cable alarm as in your link in first post, worked great for the first few times, then after some serious rain, a few days later, it started going off randomly day and night, very annoying, I think it was rust as apposed to water as did it when I had dried it out  for several days, the cable end has to make a connection so isn't fully plated, good idea for somewhere dry, used it just as a deterrent without a battery afterwards for rest of the holiday, I personally wouldn't buy another

I saw a bike alarm which was coupled to the vans alarm which I thought was a good idea that the lady had had fitted.  
Peter knows her (LI) better than I and may know more details but if the van is already alarmed it may be worth considering

Hi Roger

That might have been a Strikeback or Growler alarm from Vanbitz.  https://www.vanbitz.com/

They have a loop of cable (white in our case) that plugs into a socket under or at the rear of the van. It has a connector in the middle and is looped and threaded through the bike(s). If the connector is pulled apart or the cable cut, the van alarm goes off - and believe me, everyone in the next village would be woken up!!

Not cheap, but arguably the best alarm available.

i use a disc break lock with an build in alarm

its loud an annoying to anyone who knocks my bike  more than 2 times in a short time period, i keep setting it off myself every time i remove it

TBH no lock is ever going to stop the determind thief but they will stop the causal scum thats are not equiped with an angle grinder

my  disc break alarm lock is one of 3 i use when leaving my bike unsupervised ( my ebike bought for £2k +) this disc break lock is my "sneak" lock as  when on the back wheel well hidden by my paniers.

I bought a couple of these from Amazon Alarm They are very loud, easy to use and cheap. I attach the alarm to the bikes on the rack using some fishing line to extend the pull lead and hide the alarm behind the frame. I also use one between the front doors of the van so that if either door is opened the alarm is triggered. I have another one I bought previously on the shed door, which I am always triggering as I forget it's there. They are VERY LOUD!!

Our son has a Laika and has wired an alarm in to the van alarm system and it has an LED which flashes as well. Spent a year touring Europe parking in some pretty sketchy places and no one went anywhere near the bikes. Cost nothing, I could find out how it was done if anyone is interested. I know the LED was mounted in a piece of plastic water pipe and caps on the end sealed with silicone, it did look very professional!

We bought an Oxford Products D lock/alarm which also has an extension seriously thick braided steel cable to enable both our bikes to be locked and alarmed when stored on the locked bike rack on the van, if we're away from or sleeping in the van.

It isn't cheap at £65, but it certainly works - has a tremble alarm on it too. Try pushing, pulling, fiddling or whatever with the ensemble and the alarm goes off (120db).  It's not so sensitive that wind movement of the van would set it off, but along with the other security devices we have with our two e-bikes, I'm relaxed...…………..and so are my insurers!!
