I didn't used to dislike eBikes. Problem is, I've run into too many jerks on eBikes. I do have a friend who rides one responsibly, but, he seems to be the exception.
I think the amount of signs that have been posted at Skypark to remind eBikers to stop riding like jerks tells you everything you need to know about the people riding them.
I do know of A guy in Big Bear who rents eBikes who is an old, out of shape guy, who goes out of his way to criticize non eBikes. He calls people who can't make a technical climb 'lazy' for getting off and pushing, while he can make it on his eBike. That was on a Facebook post where he was going on about Summit not allowing eBikes (which isn't their decision). I have seen him take KOM's from a Pro who lives up there (national level pro, not a 'local' pro) and brag about how much better he is. I'm sure he is telling his renters that they can ride wherever they want.
