One thing to try: local bike shops that carry ebikes will sometimes have rentals/try it out bikes you can take home and ride. Itsa big $$$ and bike companies want your business.
One of our local guys has a trek mtb full suspension e-bike.
Something sorta like this-
He went in and tried some others while shopping, but found he didn't like the way they rode, so when he ended up with his rig, he knew he liked it. Evidently, there are some big differences in how they pedal assist/etc.
I always get a kick when he shows up to the local gravel rides on his e-mtb. It kills us below 20 mph, BUT... and this is a big BUT... If the ride goes above 20mph, he loses his advantage, the e motor turns off, and is suddenly pedaling a big fat dog. This makes for fun riding, if the group works together and on the flats pulls a nice paceline, we can drop him.
He (of course) catches up on the uphills, but it's a fun game to play. It's like Kyle Reese and Sarah Conner battling the terminator.
There are other ebikers on e-gravel bikes, but honestly, I have a hard time telling who's who these days with all the oversized tubing. The gravel e-bikers aren't gunners like the mtb dude, so they kind of mosey around in the back of the pack.
I saw a bunch of bikes like crowbob's at the beach last week. Looks good for sand and carrying stuff.
