I'd like a bike rack for my car-I have an '04 Honda Civic. I would like a bike rack that won't be too difficult to operate, i.e. my bike can come on and off easily. Needless to say, it will need to be installed on top of the car.
Why do you say "needless to say, it will need to be installed on top of the car."?
Rooftop mounts are fine, but (a) can be difficult to put a bike onto for some people and (b) have significant risk of damage to bike.
I just put a 1 1/2" hitch receiver on our Subaru and got a Yakima "tray" type bike carrier. It has an adapter to make it work on 1 1/2 or 2 inch receivers.
It is EXCELLENT and will hold any kind of bike, road, mountain, kids, bike with fenders, etc. Yakima makes another model and Saris makes a similar model, but less versitile because they won't work with fenders (which is insignificant for some).
Much, much, much better than the hatchback and hitch mount "dangling" carriers I have used in the past. MUCH, MUCH better.
