I've always enjoyed driving small cars and I just need to transport two bikes, so I went with a 1.25 instead of the 2. My little Mazda 3 is not rated for any significant towing, nor do I have any desire to do so. My Kuat NV 2.0 two bicycle rack requires only a 1.25 hitch and also swings out so I can open the hatch door with bicycles on it. I couldn't be happier. I would have needed a 2.0 hitch if I purchased the four bicycle Kuat rack.
