My 4" bumper is not "sheet metal", it is rather stout, as a bumper should be. It carries my spare tire on one of those bolt on uprights with no problems. My spare weights more than my bike that is for sure.
If I were to carry my bike I would secure it so it could not twist front to back, torqueing the mounting post.
If I were to carry my bike a lot, I would go to the expense of having hitch receiver welded to the frame so I could switch my bike carrier between TT and TV.
That's great then. If you measure the thickness with calipers and it's .250" (1/4" steel) or thicker, you should be good to go. The last 2 trailers I've owned, they were about .080" and quite thin. I do not even consider the thin ones bumpers, but rather dump hose carriers.
