Bike security chain - where?

[CookMySock]

Right, due to a minor intrusion here, I'm bolting everything to the floor.

What I'm after, is some chain that I can dynabolt one end to the concrete floor, and loop the other end around a wheel and padlock to itself.

Plastic covered chain might be good to not mark wheels etc, but can this stuff be cut much too easily?

Transport chain would be nice, but probably overkill. They'll need an angle grinder to get through that shit.

Suggestions and sources please.

many thanks,
Steve

Just got my bike so im paranoid about theft, went and purchased a oxford chain that comes with a strong lock from cycletreads.

[awayatc]

there are hardened security chains around..... locksmith/bikeshops sell them, hacksaw wont do much good on those

[CookMySock]

I guess I might be better off purchasing a proper chain with lock unit already attached, and just dynabolt part of it down.

Here's some pics of my anchor.It is welded up out of 50 mm x 10 mm flat bar.When a chain or cable is fitted through it the bolt head cannot be turned as a spanner won't fit inside with the cable/chain in place.
The bolt does not need to be tightened and the anchor can swivel (to unscrew it with a bike chained to it,you would have to turn the whole bike and chain around many times.


This is the type of anchor you want it is a 16 mm internal thread.
You drill a 19 mm hole and set the anchor by striking the internal wedge with a drift or a piece of 12 mm bar.

A security guy told me once that stranded cable as opposed to chain is better.

He said bolt cutters or a hack saw can quickly cut through a chain. He said bolt cutters don't work on stranded cable (he gave me a go, and they don't), and using a hack saw on it takes a long time.

Go to a wholesaler that deals with supplies for logging crews..........they have all the good cahin and wire rope you could ever want.
and they can splice eyes into the ends of a wire rope for you.

then you buy a decent quality lock to finish the job.

And you can run the lock device through an arrangement like the one pixie showed.

good luck

Will cost you a few hundy to do it right with off the shelf gear - Kriptonite eg makes a very good ground anchor system and hi-tensile chain which retails for about $350 the pair.

You can buy a cable lock starting from around $20 and how much is it to comprehensively insure a Hyo?

Try & find hex link chain. Very difficult to cut as it rolls. An old inner tube is good to cover the chain & I would reccommend an insurance / security tested padlock. They are rated by the number of hit's from a sledge hammer required to break them.

Most bike dealers sell security stuff, or go to a security dealers direct, lots of them around. Also get the best lock you can- no point in super hard chain and $2 Shop toffee lock.

I reackon the trick is if somebody wants your bike, a set up where they have to make a lot of noise is good, eg cutting chains, hammering etc, Ive got one of those battery powered (+ set to recharge off solar) alarms in the top corner with a steel cage which will resist a good hammer bash, the ear pierceing sound is unbareable.

Is bolting everything down an appropriate solution to your "minor intrusion"? Have you considered other options and what else are you going to do to prevent someone stealing the bike? It is impossible or too costly to fully prevent a theft but if you make it difficult the thief will choose an easier target.
Some simple things to consider:

• Alarm system on the house / garage
• Turn off auto garage doors if away for a few days
• Bike keys kept where they can't be found or got - buy a bike with a coded key system
• Know your neighbours

Security is about building layers of difficulty for a thief to slow them down and make the theft risky.

If you install a bolted down device will you use it?

In the misty annals of time RiDE mag had a feature on bike security- and some folk were using them blank shot gun cartridge "bird scarers"... Not sure if legit, but, hey!
