This seems to be an issue with the UX... I can't find a solution. I have an e-bike and I'm not the tallest there's NO WAY I can lift it onto the roof, but I was quoted £2000 by Guildford Lexus for a towbar and rack to fit. They also warned me not to go to a non Lexus dealer to fit the towbar as it might invalidate the warranty(around the hybrid battery). So atm I'm stuck! If I had realised when I bought the car the difficulty getting my bike on board I might have thought twice!
