Shoot, the reason I have a wagon is because of bicycles. A roof rack is the only way to go - it prevents boneheads from crunching your $$$$ bicycles while they hang off the back of your car in a parking lot. The great thing about a wagon is the rack is mounted to the roof rails - it doesn't touch the car's paint at all. I have a 58" Yakima rack. It will easily carry four singles, plus four wheel holders. I also have a tandem attachment to carry my tandem. It will hold three singles plus the tandem. This configuration doesn't do much for your gas milage
