Good question @The duke. I work in the industry and see lots of people hauling ebikes around with their cars... and surprisingly, some of the reps for higher end brands use what I would consider "cheap" racks... but they are always platform style racks. This is because many ebikes have step-thru frames or won't work with hang racks because of fenders, lights etc. and roof racks are super vulnerable to low hanging spaces like parking garages and McDonald's drive thru's
Anyway, I have owned and enjoyed Küat racks and the Thule EasyFold is awesome, but they are SUPER pricey. So, the one I see frequently that is less expensive is Hollywood racks (and they do have the ebike specific one that's rated to more weight). You'll need a hitch installed on your car, but that can be done fairly affordably. I installed an 1-1/4" hitch on my Toyota Prius and just remember to remove my battery pack and place the heaviest bike closest to the car to reduce the pressure and leverage of the weight on the hitch. I've never had an issue... except for when I forgot to buckle in my loaner Stromer and it fell partially off while driving through a residential street. Wow, bad embarrassing feeling there!
None of the options I'm sharing here are as cheap as the steel cargo carrier thing mentioned by @6zfshdb but these bike-specific solutions are a bit easier to work with, can carry multiple bikes with scratching them up, and probably also weigh less which makes them easier to mount, de-mount, and store (taking up less space). Hope this helps! I'd love to hear and see more about what you learn and choose based on our feedback.
