SOmebody had to defend the dudes

There is a different chemistry.
Have you considered growing yhour own? There's a reasonably good chance that there honestly are women who *would* ride if there were a supportive community. I am *always* running into the "I wish I did it more" crowd, and while a mess of 'em are just whining and don't really have any intention of changing, others... welp, others have come out on that Saturday Saunter ride that I lead... on the Gazelle or the Xtra cycle, going ouit for half an hour or 45 minutes of "peppier" riding before the ride... then the odd intervals and pushing the heavy bike along mean I'm getting further training on the Saunter.
We also have a really neat women's ride that's fast... but simply not testosterone-driven. It ain't that that's a bad thing - it's just different. (and this town's got about 100,000 people and about 200 of 'em are in the bike club... but there's been years of effort to make the club welcome at the entry level.)
