Excellent, heavy duty ground anchor, probably stronger than the floor it's bolted to!

Problem bolts

This is a substantial ground anchor. I had some trouble with the fixings. Holes were drilled to the right depth and radius, but the bolts weren't biting. SBS arranged new fixings, but in the meantime I got some better quality ones from Screwfix. They did the job!
Pleased with the end result!

Mammoth ground anchor

Would have got a 5* if the securing bolts were a better standard. Bought some from Screwfix to replace them. This is the second anchor I have purchased, very strong and good quality. Can accommodate a large Oxford security chain. Well worth the cost at this sale price.

Good quality anchor

Very well made anchor, easy to install. I'd have given it 5 stars but for the anchor bolts that go in the ground. Very flimsy and ended up replacing them with others from Screwfix.

Well made, sturdy ground anchor that has pretty impressive lock down bolts. Well worth the money for the peace of mind.
As ever SBS handle everything quickly and without fuss, ideal.

It appears to be well made and bolted down to the ground well, a little bit of reassurance.

Rock solid bolted into the ground. I've never tried to steal a bike(!), but I imagine (and hope) that this would give you some serious trouble doing so.

Solid & sturdy

I definitely recommend this product for every person who is looking for an extra security for their motorbike. I wanted something that would put any potential thief off trying to take my motorbike and which would be accepted by the insurance company.

Great anchor, let down by the poor quality securing bolts. Had to purchase 4 more from Screwfix to complete the job. The fixings that came with the anchor fell apart when dropped in the holes drilled and had to re-drill them again.

Seriously solid
18 June 2023 by Tricia H
Worth every penny. Seriously solid and well made and design. Very heavy and has a double thick layer so if the thief wants the bike they'll have to angle grind through two layers of steel.
Everything comes in the box except the drill bit, you'll need a 16mm masonry but and a heavy duty drill. My cordless drill was nowhere near powerful enough to drill into the concrete.
It also comes with ball bearings to hammer into the top of the bolts rendering them useless so the thief can't undo them, as extra security I would recommend some liquid metal squirted in just to finish.
I definitely recommend this product and a great delivery time from Sportsbikeshop.

  • What is the diameter of the plate that is fixed to the concrete?

    September 27, 2017

    The diameter of the base is around 7inches.

  • Are the fixings/bolts supplied with this item?

    February 16, 2013

    This item is supplied with all the fixings needed to install it.

  • What size drill bit is needed to attach it to a concrete floor?

    August 13, 2012

    The drill bit required is 16mm plus probably a smaller size for a pilot hole.

  • Can you attach the anchor to a brick wall?

    May 16, 2012

    It may be possible to locate the ground anchor to a wall depending on condition and size of brick work. For security, the anchor bolts would need to be located into the brick as opposed to the cement work.

  • What is the biggest chain this will take?

    The dimensions inside the inner clasp where the chain will be located are approximately as follows: Height from top of base to underneath of clasp = 45mm. Width of clasp opening at base = 85mm. Width of clasp opening at top (beneath clasp)= 50mm.

  • I am searching for a great outdoor security post/anchor, and just don't understand how these will work - could thieves not just unbolt the anchor from the ground??

    August 25, 2011

    The ground anchors are supplied with hardened steel ball bearings. Once the bolts are secured to the ground, the balls bearings are tapped into the screw head preventing access by allen key etc. Some models of anchors have further inserts which tap in to an undercut directly above where the screw is located.
