After looking at that seat post mounted hitch it looks like I need the other end to take care of the up and down rotation, like on a hill or gutter. This ball might take care of that but now I am thinking of that axle mounted design.


@ hokiefyd - thinking of the front wheel idea, but would that create a strange connection between the bike and trailer? I guess maybe pivot points a both sides of the connection. I imagine the bike going down a curb and the trailer then pivoting on the front wheel and the rear wheels coming off the ground?
