Removal of a Defiant Immobiliser ground anchor
Discussion
I’ve sold my bikes due to having a break for a while (new baby)
I’ve had a pair of Defiant ground anchors , combined with Almax chains / squire padlocks to secure my bike until they were recently sold.
Well the time came to remove them. I was told I wouldn’t be able to cut them, or pry they in any way. I was told it would require the concrete to be cut.
Well …. A few taps with a sledgehammer saw them both snap off
They were fitted correctly, and flat to the floor. The actual prongs that go into the floor are only welded (poorly) into the anchor. Very poor penetration and you can see what it wasn’t connected entirely.
I purely want to warn people as I’m so glad they were never put to the test. Please don’t fall into the trap of thinking they are more than a visual deterrent.

As soon as I saw the title I remembered something that happened a few years ago when I was still in the fire service.
One of the guys on my watch had bought a house with a garage that had a ground anchor concreted in, he was advised by the seller that it was invulnerable to any kind of attack so he apologised but he was going to have to leave it there.
Steve however wanted it out so he could have a totally flat floor for gym equipment and mats.
He asked the gaffer if we could possible swing past the house in the fire engine at some stage and see if the RTC hydraulic kit would make any difference , "it would be a great training exercise," he argued.
"Piss right off!" he was told. "What if we break the kit trying?"
A few shifts later he came into the station with the ground anchor he had removed by himself using nothing more than a sledgehammer and a jemmy...

I have been disappointed with the quality and longevity of a few defiant products over the years, unfortunately they are cheap so my customers keep buying them and act shocked when they fail.
They were £85 each plus around £250 for the chains so certainly not cheap compared to many on the market. d8mok said:

Surely the rods should extend right through the anchor….and be properly welded?
No they are simply welded and not connected to anything. The rod inside is a flush cut so wasn’t connected for sure Rubin215 said:

I’d asked a mate to come help. Who came armed with some big tools. It could of been knocked out by 11One of the guys on my watch had bought a house with a garage that had a ground anchor concreted in, he was advised by the seller that it was invulnerable to any kind of attack so he apologised but he was going to have to leave it there.

Yes, saw that…I meant that for them to work properly they SHOULD have been welded properly and pass right through the actual device.
Totally agree. The internal bar is just rattling around inside. You can even see how poor the welding is on both. It was maybe 1mm inserted inside the yellow anchor.

That is shocking!
As has already been said they should be part of the yellow frame and go up and along and out the other side, not just poking into the bottom. Wow!
I had the Almax chain and the circular anchor, and I just looked and they only have the Defiant one now (If they see this thread I doubt it will continue). Do Almax own Defiant?

Once the bike community media get hold of it they will react.
What can they say though really? I had two and both did the same so it’s not a fault unless it’s a batch. Video had 2.9k views overnight which is high I thought for such a video.
I’ve spoken to Almax today who after several minutes of not understanding about how it failed (he kept thinking it had come out of the floor) but now gets it I think. Told him to watch the video and then decide.
Says he will contact the manufacturer and come back to me. They should be welded in a loop but both mine wasn’t.

What are the in-ground anchors? Rawl bolts or just threaded bar?
Edit: Just googled them. Looks like a bit of flimsy rebar! Looks naff.
I've got a heavy duty eyelet fitted with M16 rawl bolts, and that would definitely take more than a few taps.

It should be a U shaped bar that runs inside the outer square anchor apparently
Both mine weren’t. They were around 6 inches of bar / a tiny weld / and then a separate piece of bar inside the anchor.
They are held in the ground by a chemical which has stayed good. The fault is the anchor itself.
This is what they look like complete
