i can put my bike in the back of my ek sedan no problem, 2 bikes is harder, but 2 people and 2 bikes is doable with patience

im not a huge fan of rear racks, but my parents have had about 5 of them over the years
they all worked, but the better ones had easier adjusted straps, and rubber coated metal clips, none of that plastic shit

getting the straps on tight and using an extra bungee or two to keep wheels and cranks from rotating helps out a bit

overall i would invest in a used yakima roof setup, can be found for about the same price ($100) as a rear rack and much more stable, and you dont have to worry about being rear ended by an idiot and having your bike totalled
