As owners of a 2013 CRV, we are looking to purchase 2 electric bikes and need to find a way to transport them. They would each weight 24 kgs. As we tow a caravan and want to take the bikes with us we cannot use a tow ball fitting carrier. Would prefer a rear vehicle option but are having difficulty finding a suitable one. Have seen roof mounted options but as these bikes are quite heavy a) they seem to be too heavy for the roof bars and b) as we are not getting any younger we are not sure we would be able to lift them anyway. Wondering if anyone else has come across this and has found an answer.
