All the technical stuff is good but it's gotta happen 'upstairs' too. Get her information, photos etc about other women bikers (triathletes too). Not that she can't be inspired by men but seeing another women rider or competitor was a big motivator for me. Bicycling magazine, though a bit simplistic, is always very balanced too.
She must be inspired. She HAS to come to it by freewill because biking is like religion.
OK, maybe not exactly like, but kinda.
Get her on this forum, we women'll set her right.
