The rack I've been using for the past 10 years or so is not rated for the bikes we carry. It's for bikes under 30 lb each. So, we've been on the hunt for a new bike rack. Wow, how this market has changed in the past few years!
Lots of $500 to $800 2-bike platform racks out there now. But even many of the $500 racks are not capable of carrying a couple of eBikes due to weight ratings.
I searched a LOT of racks and just last week bought this one from Amazon:
Vibrelli Bike Hitch Rack
https://www.amazon.com/gp/product/B08B5M9C4R
I haven't used it yet - so it's too early to tell but it's 130lb weight rating, tilting and locking features looked pretty good. At least I hope to find it a good rack. We have a 6 week 3000 mile trip coming up in 3-weeks. I guess I'll know for sure after that trip is complete.
PS. A lot of racks are not rated to be used behind an RV. They say the motion behind an RV is hard on the rack and therefore they are not warrantied for that usage. And many add behind a Toad as well to that. My new rack is not rated for behind a Toad or RV. But neither was my old rack that spent 10 years behind my travel trailer, Class C, Class C Toads, Class A and Class A Toad.
