I want to fit a tow at to my CX-60 PHEV to carry my cycle rack - I only need it for carrying two electric bikes and will never tow anything. Supply and fit with electrics at dealers is around £1.3k for the retractable tow bar. Any recommendations for supply and fit and I’d prefer not to see the tow bar when I’m not using it - I’m located in Essex but prepared to travel for a reasonable deal?
