We've had to move to a 4 bike carrier now the kids bikes are getting too big to go in the boot, so selling our old 3 bike carrier.
Towbar mounted, tilts with bikes on so you can still get in the boot when loaded, easy to get the bikes on and off. The carrier isn't in perfect condition, a couple of years ago it took the brunt of a low speed rear impact which bent the mounting point for the number plate (now straightened), and required a new lighting board. We've done thousands of miles with it fully loaded since then, and I wouldn't have used it if I wasn't confident it was entirely safe for both other road users and our bikes. It's priced low to reflect this damage.
I believe the exact model is 9403, happy to supply photos and more info.
We picked up an old-ish Halfords one second hand. Offers the basics that we need i.e. 4 bikes and a tilting mechanism and seems solidly built. Downside is that it's heavy, suspect newer versions would be a little lighter.
