Can anyone recommend a good reletively inexpensive ground anchor? It has to be a bolt down one as I dont want to dig uo the garage floor to set one in concrete.
I have one but what I didn't realise was how long the locks need to be as anchor will obviously be on the ground. If you have more than one bike to lock, it all becomes a PITA. I believe mine came from either CRC or Wiggle.
I've got one of [url= http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=9284320&fh_view_size=150&fh_start_index=0&fh_location=%2f%2fcatalog01%2fen_GB&fh_search=ground+anchor&fh_eds=%C3%9F&fh_refview=search&ts=1242229628712&isSearch=true ]these[/url] and a heavy duty motorcycle chain keeping my babys safe
goog, what does your baby keep in his/her safe?
Used to use an M12 threaded eyebolt screwed into a Rawlbolt fixing. Relatively cheap and strong, just make sure the lock you have will pass through the eye, and fit it close to a wall to prevent the whole bike being turned to unscrew it.
have a look at these;

not cheap but then neither are your bikes!
Seen a few bolt-in ground anchors done with normal hex heads and allen bolts, seems like an exercise in futility to me. If I was going looking for pricey bikes to pinch you can be damned sure I'd take some basic tools in a bag to undo such things! Make sure you get one with anti-tamper bolts. Make sure you know where you want to put it as you'll then never remove it 😀
anti tamper bolts by either drilling top or hitting a ball bearing into them
i've got my dad building a ground anchor for the motorbike. most of the linked here i wouldnt trust more than some soft chees to keep my stuff safe.
what you want is a box section with a plate on the bottom, you bolt through the plate into the ground. the chain then passes through two holes in the box section over the top of the bolt holding it down so that when there is a chain in you cant unscrew it but when there is no chain through you can easily remove it should you need to.
i had a pic saves some where but cant find it now.
I got mine from halfords... even came with the bearings to smash into the allen key heads.
google Almax.
Having rearraged my garage I tried to 'remove' my Datatool one. With an angle grinder and a 24" crow bar, I lost interest in trying after 1/2hour and decided to just ignore it and put my workbench over it. It was of the rawl-bolt + bearing wacked into head veriety. I was suprised how simple and effective this method was.
A 12mm eye bolt, unless welded, could be prised open in seconds with just a hammer.
i would like one in my bike cupboard but its only plasterboard walls and the floor altho concrete has underfloor heating so cant really drill it in anyplace was thinking of lifting one of the tiles and using some of that araldite stuff to glue it to the floor but not sure how strong this would be
some one suggested a big bucket of concrete with a D lock cast into it. just pass your chain through the exposed part of the D and you are sorted. not the best idea but if its a big enough bucket its going to seriously slow people down.
I found Saunderson Security was one of the cheaper suppliers once postage is taken into account.

I bought the first one and the PJB Bullpoint anchor, when the time came to move them, it took me three sessions and several hours of swearing before I found a successful method without breaking up the floor.
When choosing the location make sure it as hard to reach as possible, i.e. against the wall and under the bikes.
B&Q do one for £20 or so, seems good although your floor needs to be good to take the bolts.
I've got four (yes four) of these Oxford Brute Force jobbies bolted to my garage floor and then daisy-chain the chains together. I hope they would take some shifting.

At £19 a pop you can afford to have more than one.
