Lots of e-bikes out nowadays. I have noticed that. Normal bikes- I have been passed by 4-5 women in the past few weeks...all on race teams, if their bodies and gear was any indication. That said, it is just luck (and my deserted routes, I guess) that I don't get passed by women more on the uphills. I know of a few fast ones. I'm 48 and hoping to get better and better.
