We have a Peugeot 206. We carry bikes on the roof, with a pair of Halford's roof bars and an old pair of bike carries of the type that carry the bikes upside down, standing on their saddles and handlebars. (I haven't seen these sold anywhere lately, but Halford's used to do them).
I find it very much easier to get bikes up on the roof with upside-down carriers than right-way-up ones. You lean over the bike, grab it by the seat tube and forks on the other side, and swing it up and onto the car in one movement. When you come to lift a bike onto a right-way-up carrier, you have to lift it far higher because the bits that end up at the bottom are the wheels and chainset. The one spins round when you grab it and the other is oily...
Why have the upside-down ones gone out of fashion?
