All kinds of stuff to choose from.
The only warning I have it most bikes don't have the normal cross bar as many are at some type of angle, so getting one that holds the bike via the cross bar may require the adapter which is another 30 bucks per bike. It clamps onto the head tube and seat post. Looks like a big paper clip.
I have a draw tite rack that holds 4 bike and is industrial strength. Tilts down to open the hatch. With the 570 hatch opening both ways you may not be able to open the bottom half. It also has tail lights on it as it does cover up the vehicle lights when fully loaded.
Also think about some type of cable lock to slow the bike thief down if you plan to travel and leave the bikes on the rack. Been there done that.
