I have not installed a single bike 1UP USA bike rack in to my 2" Curt receiver. I bike 2-3 times per week so in the warm months I leave the rack on at all times. Is there a way to temporarily disable the rear parking sensors? The sound is VERY loud and is continuous while backing up. I have read that fitting a trailer light plug to the trailer wiring might disable it (supposedly it does on the European spec models). Has anyone tried this?
