DIY security - buy chain from a supplier

pilsburypie

Posted a short while back about diy security. Got a good idea for a ground anchor cemented into the garage floor which will be covered by steel plate to stop the concrete being hammered. Anyhow, to fix the bike to the anchor I assume chain and padlock is the order of the day. The majority of crooks I'm guessing will have bolt croppers, levering devices and impact devices like hammers. Bike chains tend to be expensive so was thinking about just buying some chain and making a nice protective sleeve myself.

What size chain is gonna be a problem for a crook? I know what it is made of will also help...... Would any of this stuff be better than branded security?

10mm case hardened chain 1m £26
14mm standard chain 1m £19
13mm boron security chain 1m £35 http://www.chain-supplies.co.uk/security/
10mm boron security chain 1m £20 http://www.chain-supplies.co.uk/security/

Also, Padlocks? http://www.nothingbutpadlocks.com/produ ... dlock-65mm

I'm aware of some bike specific stuff but feel it maybe cheaper to DIY it - I need 3 securing devices for 3 bikes.

none of those are suitable, you want AT LEAST 16mm links to prevent bolt croppers from working, read this

Ideally Surface hardened to give them lots and lots of grief.

The same applies to padlocks.

Bloody hell - big old chain. :shock:

I bought a chain lock and ground anchor from Pragmasis, I got a 4 metre / 13mm chain with Squire lock and ground anchor with resin fixings for £193 delivered. They do 2m for £143, which would secure 3 bikes (I have 9 secured).

The ground anchor seems very impressive, but even then, because it is mounted in the middle of the bikes it would be impossible to attack without removing the bikes first. I also ensure the chain and lock can't be put on the floor.

I think your DIY approach may not save too much and it may offer less peace of mind.

(I still have extensive insurance as I am not convinced anything will be foolproof).

They do 16 and 19mm chains as well.

I'm insured too, but still would like to stop the crook. I was thinking DIY as I'd like to go the route of 3 ground anchors and 3 chains and locks so if they get 1, they cant get the others....

Do it with one thing properly, they have most of the night to work on each point of weakness so it is better to have one decent bit of security than 3 poor ones.

pilsbury, mix and match:

i'm putting in some new secirity at the moment, i'll post the full measures but think that layers are appropriate, my 3 tiers are door, ground anchor(s), alarm

i'm luckily able to get a proper security door built to fit the opening (masonry) at cost, th

i think an individual anchor for each bike is a good idea AS LONG AS YOU THEN chain em together, they have to go thrrough a minimum of 2 fastenings per bike then:

for me cheapest bike goes on the least secure (epoxy bolt in job + cheapish chain/lock from a builder supplier), poshest bike on the most secure (large steel "0" wrapped around a load of rebar and concreted in + specialist chain/lock).

not thought about the alarm yet

pilsburypie

Like the idea of them all chained together as well. I forgot to mention this will be in my locked alarmed garage like yours.

Try Almax stuff as well, as good as Pragmasis stuff

When I have to keep stuff outside I am buying some anchor chain:

Won't be as tough as the case hardened stuff, but you ain't gonna get bolt croppers around that!

Now thats what I'm talking about. Pretty cheap and monster thick. As you mention Mr Supersonic, not as hard as the boron stuff, but the crook is going to take one look and not even bother trying.

This is well worth considering for me and just cementing into the floor.
I will also have a locked garage door and alarm.

I'm afraid lads that if the thieves have one of these or similar with a steel cutting disk , nothing will stop em..............Apart from their noise of use.

yeah, has been said many times, if they are determined, have the correct tools and plenty of time when they wont be disturbed then they will take what they want.

but by securing stuff properly you narrow the range of tools which could be sucessfully used and increase the ammount of time taken and the chances of them being disturbed.

Plus it sends out a message:that you will look after your stuff, people who place all their reliance on insurance and come up with sniffy "whats the point" comments encourage the scum IMO.

apart from pros stealing high-end stuff to order most are chancers who are after anything they can sell on and these will be detered by a decent security set up.

pilsburypie

That's why a locked garage which is alarmed and bikes secured with thick chain and insured is the way forward.

There are loads of tests which show amost every bike chain useless in less than 60 seconds with the right tools. Just after making it as difficult as possible

...with the caveat that the security is compliant with teh insurance company.

It does not matter if the thief gets the bike and the insurer pays out.

My insurer demands a 5 lever lock on the shed and a solld secure Gold standard chain and lock secured permanently to the floor. I've done that so I'm safe.

Almightydutch

I'll back up the Almax chain. Have had one round various motorcycles over the years. They really are the tits!!!

really? itl matters to me that some scum has been on my property and taken something, and i'll do my damnedest to make sure that next time they leave empty handed (or get caught). insurance or no i'm furious.

also your premium WILL go up (as will everyone elses).

less of the defeatest attitude!

BlueAdvocate

My original Rockhopper and old Marin Muirwoods got nicked by chancers. I left the door unlocked as I was using the dryer.

My fault.

Door is always locked and bikes are chained up inside; ground anchor could be better and cable could be thicker but the garage is alarmed.

Hmm insurance, thats another story.

Yup, but grinders are very rarely used. And no wonder when silent attacks will break most bike locks faster than they can be undone with the key! Theftproof is impossible but if you make it hard enough, the fact that most people lock up their £2500 bikes with £10 tesco locks means it makes little sense for a thief to bother.

They'll never steal your bike if you cast it into a 6m cube of steel reinforced concrete, unfortunately you'll no longer be able to ride it...

its 19mm long links not 19mm thick.

supersonic

Are you sure? The one they had on before {though could be different} stated 19mm thick links, and gave much longer length. This seems to agree with the priceing structure too.

I shall email them.

pilsburypie

Emailed them the other day . 19mm thick wire, 75mm x 28mm internal dimensions. £16 p&p for 3m of the stuff.

Might not be the hardest stuff but will put most off just by looking at it!

Based on the 13mm and by the time you've bought 2 metres you'd be better off getting the Pragmasis chains.
