one of the things the local Trek store does that is really great is that they offer a beginners maintenance class every couple months. It's advertised in store and allows beginners to show up and learn the basics. Like how to change a flat, how to clean your chain, how to use a patch kit, how to release your brakes... and the names of the different bike parts...

LOTS of women show up to these... perhaps offer a womens bike maintenance class... ? Either way, it's a great way to help new riders feel comfortable and not feel "dumb" for not knowing everything automatically!
