We have just swapped from the VW rack to the Atera Genio Pro. Very pleased. It's a well made piece of kit and very much eases getting an e-bike on and off the rack.
If you can lift the front wheel of the e-bike 30-40cm from the floor, you will get it on no trouble, just sort of push it up and on to the rails and roll it over the hump.
The boot lid opens without issue with the rack tilted down.
The heaviest part of the exercise is lifting the rack on to the tow hitch. We tend to do that as a pair, one on each side and that makes it a lot easier.
The cover is worth having for when it's stored. After some faffing, we worked out that it is best fitted to the rack while it is still on the van after the ramps have been folded up. Then lift the rack off by gripping it through two slits in the top of the cover and finally zip the front up when it's on the floor.
