I’ve gotta question how good those towbar mounted carriers would be.
Not so much on the carried bike but the stress on your cars towbar mounting points. Say you put most full sized bikes on it you are looking at around 115kg of down pressure on your towbar. That seems somewhat excessive to me, but thats only static weight. If you add the normal dip and so forth that your car has when driving along the road or fire trail going into the bush would that not amplify the downward weight on the tow bar?
I am not knocking those that have these carriers or reckon that they are a good thing but I just dont buy that they would be all that good or safe in use.
