I've got multiple bikes and I want them all chained up in my garage.

I recall seeing someone had a central ground anchor and then 4 chains BUT they were single lengths of chain (NOT looped so the chain is twice the length)

What ground anchor can hold multiple chain ends ?

All I can think of is a shackle through the anchor but I don't like that idea as it means one cut releases 4 bikes, 4 shackles add up and create a big trip hazard, I'm sure he had a better solution.

I've never seen that configuration before.

Personally, I would go for individual anchors; as you pointed out, defeat one anchor and you have released four bikes.

If nothing else, four anchors/four chains takes longer and makes more noise.

I saw it in a guy's garage when I went to buy a bike and thought how neat and simple it was but I can't picture the anchor.

Currently mine are daisy chained together - garage is alarmed and I'm generally in so I just need to stop them getting anything out in 60 seconds ish

I was a bit shocked when I saw footage of a theft the other day - 4 blokes picking up bikes and throwing them in a van, just so fast.

I fit the anchors to the wall (this assumes brick built garage) this means I can fit them 'between' the bikes and at front and rear. I have bikes against both side walls. This allows either locking the two bikes with one chain though rear wheel on one and front on the other or each one individually chained either by front or rear wheel or even each bike chained front and rear (in theory as currently I'm short one lock and chain to do this. Garage is also locked and alarmed and attached to the house.

Please remember that proper bike thieves (not London-scooter-rats) are people who will not think twice about giving you a right good hiding if you try to stop them.

Unless you are some kind of ninja warrior or carry firearms, I would just let them have the bike...

The problem I have is it's a double garage, half is a gym and there's a row of shelving along the other wall and a workbench at the end

Sometimes I put a car in there and move them to another garage, sometimes I move them around so I can work on one so a single central one would work best

I've found an Oxford docking station which could be used for 2 chains and I could chain two bikes together but I'd rather all 4 were separate

I recently made my own to fit in a 4" slab. I've got the ends of two single chains trapped in a fence post shoe... I wanted just enough links so they can be locked to but can drop out of the way.

Good idea, I was thinking about concreting the chains in but I want to remove them.

You can get anchors like this;

Then sink them. Just be sure to reinforce the concrete with additional rebar (or scrap) and try and get the mixture right so it's not brittle.

You'll not get multiple chains in a single anchor. Decent chains are just too thick.

Yes I've seen them thanks.

You can get two in the Oxford one I linked to (although that's not what it was designed for)

I'm thinking about using the Oxford Magnum D lock to hold multiple chains - googling shows it's 16mm and Sold Secure Gold and yet is on offer for £20 which seems very cheap, I suspect I'm missing something.

He’s harder than that. He’s a PH’er. He’ll dominate the garage.

Goatee'd, powerfully built, company director type you mean?

In all seriousness, a guy I knew years ago came home to find his garage open, his bike gone and the family dog lying dead in the hallway; the poor mutt had obviously been making too much noise when the bds had broken in so they cut its throat and left it to die.

You're dealing with scum here, and scum don't give a fk about you or me.

First rule of ninja firearm club...

I agree that you can't stop the 0.1% so let's focus on stopping the rest of them

Or as with the "you can't outrun a lion" analogy - I only have to move them onto the rest of you

Do you actually need a ground anchor with 4 bikes? Just chaining them close together, including through wheels, would them make a very hard obstacle to move. Thieves would have to drag each bike forward a few inches at a time, and they couldn't still get them into a van without a tail-lift or hiab crane. Using several separate locks and chains would create a fun puzzle to delay and dishearten the scum - 16mm noose chains from Pragmasis ideal, you could weave them all over the place.

what about a pragmasis anti pinch pin through a ground anchor? available in various lengths so you could get a tight fit and 24 mm in dia so thicker than the chain looped onto them

I wasn't aware of noose chains until earlier today, they achieve a lot of what I'm after, unfortunately I already have 4 chains.

I'm always fiddling / moving bikes so locking as one block wouldn't work for me, my concern was, the oiks grab a bike and pull, damaging all of them in one go.

I like the pin idea, wasn't aware of that either but the Bulldog locking pin is IMO a better design, I'm thinking of making something using it.

In the meantime I've bought two of the Oxford Magnums for £41, I can loop them through the anchor and out to bikes on either side, giving me flexibility and if I upgrade later they'll come in handy somewhere.
