The trailer frame is tapered out towards the bike and there is plenty of clearance for angle of lean. The trailer is balanced on a tiangle of points its wheel and the 2 ball joints its also pivoted thru the vertical at the front of the trailer. So no problem when stationary. The only problem with mounting this way when fully loaded backing the bike up takes a little getting used to as the trailer trys to dictate the path, turning the bike while backing up tends to tip the bike sideways on the ball joints. Not a big deal but can be a bit tricky on tight manouvres. Its a small price to pay for the other advantages. Of course you can allways un hitch. Unloaded or light loads its not an issue.
