My wife is approaching 60 years young. She currently rides a 19"Trek FX-2 WSD. (but not a stagger or step through frame) She has osteoporosis and figures if she wants to ride for 15 more years she will probably need a step through frame. She doesn't want to go to a comfort bike. She would like to make a step or two up in components when she gets the new bike. Something like the FX-3 or FX-4. The problem is Trek doesn't make them in the stagger. They do make the FX-3 in a 17.5" which is a little small. It seems pretty spendy upgrading components after the purchase. Does anyone have any good ideas? I have heard other bikers say the same thing. With the increased popularity of biking amongst older people, perhaps if Trek heard from potential customers they would offer the stagger as an option in those models.
