I really enjoy my ebikes. They got my wife riding again. She's 66. If we blow by someone on the bike path and that angers him, well we're only going 12-14 mph and maybe that guy needs to get more conditioning. I go a little faster by myself, but I like to ride at low or no assist levels and still come home needing a shower after a ride.
What you won't see from us though is two riders coming at you or in front of you, taking up most of the bike path. I just don't understand the lack of riding etiquette.
