We just completed a 2500 mile trip with two Radrover 6 e-bikes on the back of an RV. We used the Hollywood Bike rack made for a flat-tow (RV Rider E-Bike Rack - https://hollywoodracks.com/collections/all-bike-racks/products/rv-rider). It worked great! We traveled with the bikes covered and added a Beacon brake light with license plate holder (Beacon Bike Rack Light Bar - https://bikeracklight.com/product/bike-rack-light-bar/). We used a Pro Tool Bike Cover (XL - https://www.probiketool.com/us/product/bike-cover-for-outdoor-storage-travel/).
The combination of these made for a great trip. The bikes were safe, easy to access when needed. It was expensive and took some practice to get it all set up properly, but was worth every cent and minute with the peace of mind it provided.
