We have a 2 bike rack that works with a 2" receiver hitch I have bolted on to the back bumper of my 5er, works pretty good. Bought the receiver at Camping World, and the bike rack came from
Walmart, it's the V-shaped style that hold the bike by the wheels. I also have a ladder mount rack, don't really trust to to hold a heavy beach cruisers style bikes, (I'm a big guy so I have to have a 1 ton bike haha). The ends that hold it onto the ladder are plastic, if was a Christmas gift that came from Camping World. If I used it I would also strap my bikes down to the ladder for safety.
