Can I take 3 bikes with me?

You're fine. Four 200 lb adults is 800. Others tow much heavier trailers with no issues even if it's against factory recommendations.

 

There are 2" hitches for the Prius (Example) and there's no problem with having one or using it for light duty, like a bike rack with 3 bikes. There's no real point of putting a 2" hitch on a Prius though (unless it's main purpose is for such a bike rack). Generally 2" hitches are for class III-IV trailers which are 6,000-14,000 pounds, way out of range for the Prius. I don't think I would ever tow more than 2,000 pounds with a Prius (and then only at *low* speeds in town), which a 1 and 1/4" makes a lot more sense for.

If you don't mind the pain that's involved in mounting it, I would look at a trunk mounted bike rack. With a top mounted rack, you're going to get a lot of additional drag. Otherwise the hitch racks are a lot easier to use.

The user manual I've seen states the maximum weight that the Prius can carry as 810lbs (I think the number is on the door jam). Using that figure, 400 lbs of passengers and 100 lbs of bikes and bike rack would still leave you with 300lbs. leftover for cargo.

I use a trunk mount with 3 bikes. Saris bike trunk mount holder. Works like a charm and took on 10 hour road trip

Get a 1 1/4" to 2" adapter and you're good to go. Available at any auto parts/sporting goods store or Walmart, etc.

 

$109 for the draw tite hitch and $35 for the allen sport 3 bike hitch.

You can get a 2" adapter if you plan to also tow a trailer but is has to be a drop down adapter i believe for it to work correctly based on the prius's height. Then you would also need a light adapter kit to get the lights power.
