I just got this bike (Trek 7200 Hybrid-Women's) through a program with my work, and had to order the bike through the mail. They took my measurements (5'8, 32-inch inseam) and sent me the 16" frame. This feels way too small for me! The next size up (the biggest size) is 18.5". I think that would be way better for my height. Anyone have any experience with women's sizing, and what would be the correct sizing with a hybrid bike? I can order the bigger one and send this one back, but I don't want to do this if it is too big. I can go to a bike store and test it out, which I will probably end up doing, but I'm a single mom of an almost 2 year-old so thought it may be easier to check with someone with experience on here first. Can anyone offer any advice? (I do have pretty long arms-I adjusted the seat as far back as possible and the handlebars are as far forward as possible and I just feel kinda squished).
