Good price and tough, does the job
This thing is huge!! And looks extremely capable. Only problem I'm having is finding a drill bit tough enough to drill the holes for the bolts.
Great product. Easy to install, QR code for installation instructions. Easy to follow.
Bomb proof once fitted. Definitely worth it.
As always fast delivery by Sportsbikeshop.
This is a really good ground anchor at a very reasonable price. It's big and heavy, exactly what you need.
Fairly easy to fit, drilling four holes in concrete isn't much fun though, but worth it for the end result.
Ordered and arrived within a few days ground anchor is a solid bit of kit you will need a 16mm drill bit which it doesn't tell you
Bought for a bit of extra security in the garage, bigger and heavier than I expected, easy installation.
I needed something to anchor my bike. This looked like a small anchor so I got this as I have limited space. This thing is huge! I got a 13mm chain and was thinking the anchor would be too small on reflection. Nope. Easily holds the chain.
The anchor itself is very easy to fix in place and once it's in, you use the ball bearings that come with it to hammer out any way of removing the mount in a hurry. Make sure you have put it where you want it!
Very happy, would and have recommended to a friend who has just bought a bike.
Straight forward to fit. Looks strong and like it will protect my bike
Good product, heavy bit of metal, would be nice if it had a 16mm drill bit with it to aid fixing, but apart from that this is the 2nd once purchased, and would buy again if needed.
Substantial bit of kit, easy to install. Instructions available online if needed. Hope I never need to move it now it's fixed in position?
Great product and very sturdy. Its a shame there's no details about what size drill is required (16mm by the way). I had to order some replacement anchor bolts as one of them came apart in the hole.
Took advantage of the reduced price. Heavy duty and makes my other ground anchors look flimsy. No fixing instructions though. Graded it excellent for its robustness. This was regarded as an applicable security product by my insurance company..
Very strong, safe and secure piece of mind knowing when I go out l know my bike is securely locked away in my garage.
Excellent, heavy duty ground anchor, probably stronger than the floor it's bolted to!
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!
Great piece of kit, thick steel plates welded. There are metal balls to secure the bolt heads.
Excellent piece of kit, heavy duty construction. Not installed it yet but looks a very substantial anchor point for my Oxford HD chain..5*****
Great piece of kit, makes me feel at ease knowing my bike is chained up to this

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, 2011The 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.
