A three-dimensionally shaped cover that is pulled up from the rear towards the vehicle and thus also protects the underside of the bike rack. A larger area at the rear facing the vehicle is also protected, but not completely closed. At least the bicycle handlebars facing the vehicle must be positioned crosswise. Incl. 2 rubber tensioners with hooks, which must be pulled into the hollow seams on site. With large clear glass pocket for the warning sign.
