To carry 2 fat tire e-bikes with your 2022 Hyundai Ioniq 5 you need to install the Cust 2" Trailer Hitch Receiver # C98DR so you can use a platform style bike rack.
For a bike rack I recommend using the Hollywood Racks Sport Rider SE Bike Rack for 2 Electric Bikes # HLY84FR which can handle 80 lb bikes with up to 5" wide tires. This uses arms that secure the bike in the middle of the frame so if you don't have a horizontal top tube you'll also need an Adapter Bar # HRBA-PRO for each bike.
