Recommendations for rear (not hitch) mounted bike carrier for hatchback?

[BikeDutchess]

You can have a hitch installed without all the wiring, just for a rack (rather than towing). If you never plan on carrying more than 2 bikes, a class I hitch is sufficient. We've tried various strapped racks in the past and it seems we could never get the straps tight enough to feel really secure. And it's really difficult when it rains en route because the straps would stretch. But others may have had more success.

I also have a Prius (3rd generation model, 2010). I purchased the Allen MT1 compact folding rack. It works ok for me. I think I would prefer a hitch rack but I'm not interested in spending the $$$ to do that. I only ever carry my own bike. I am able to get the bike inside the car without removing the front wheel and my bike is a hybrid flat bar.

Here's a picture of how I have the rack mounted low on my Prius, which is my preferred rack placement.

It looks like the Saris Bones gets very good reviews.

I could never trust a rack that had straps. I've driven to rides twice with a friend who has this type of rack for 2 bikes and I looked back so many times, my neck started hurting! My bike easily fits in the back of my station wagon with the rear seats folded. It also fit in the back of my small sedan, because the rear seats folded, too. However, it was a little harder to fit in, and I have a small bike.
I had a Saris Thelma rack on that car for awhile, until I broke the Acton car wash and they banned me from going there, until I took the rack off. I sold the rack, finally last year. My DH has a huge Saris platform rack with an extender for 4 bikes. We take that car when we are going somewhere together. I would look into getting a hitch that is just for a bike rack. It's worth the peace of mind.
