Transporting Folding electric bikes

Lots of ways, you can get a bag for folding bikes, fold them up put in bag (1 each) then put in boot of car. There are bike racks that will fit the tailgate of the car which could carry the bikes, or you can get a bike rack that fits on the towball (while towing) that the bikes fit on. When we had a caravan we used the last 2 methods as at that time we had full sized ebikes so couldn't get them in the car.
