Don't need a bike mobile as most of my rides start from my house. Even events that start up to 15 miles away are ridden out to. However- If we do go for an event that needs transport, The roof rack gets fitted to my MPV. That is for the Tandem, and then the bike rack goes on the back for 4 bikes with the wheels taken off and put inside. 6 riders, 4 bikes and a Tandem with all the day clothing and spares take a lot of room so it is a good job it is a 7 seater with the MPV acting as Backup vehicle to meet us at 3 or 4 points on the ride.
