I have been looking for a solution to carry my mountainbike during the big lap. The roof is no option so I looked at racks that go into the hitch. Some racks allow you to lower the bikes when not in use but they are often not offroad (or if they are then they are close to 800). Ideally I would have something swing away or on the spare tyre (but not sure if it holds the weight during offroad).

Did anybody made something themself or can recommend something?
