I've seen nothing like that in my locale. People debate about the merits of e-bikes, but it's good-natured. I've even been asked why I don't ride an e-bike.

One of my tactics for getting rid of somebody is just to slow down. It's counter intuitive, but remarkably effective. My theory is that very few people actually care enough about harassing someone, to put up with matching a really slow pace.

Also, if you're riding slowly in the right lane, and they match your speed, then they're the ones who get yelled at for blocking traffic.
