Sorry
@BurroBabe , for some reason I am not getting notifications from this forum (maybe because you didn't tag me, but I thought I subscribed to this thread), so I didn't see this post until now.
Unfortunately, Trek may have small road bikes, but their e-road bikes are a different story. The smallest size of the Domane+ is a 49cm, recommended for riders with 29-30" inseams. Maddening. They have gone away from the XS, S, M, L, etc. sizing to cm sizing, and those of us on the low end miss out. My current road bike (non-e) is a 2007 Trek Pilot 5.0 WSD (yes, back when they did women's specific design), and is a 47 cm. So their 49 cm unisex is a non-starter for me.
Since I had such poor luck with any stock bike, I have ordered a Lennard Zinn custom road e-bike and should have it within two months. Standover, top tube, everything will work for me now. It's way more than I wanted to spend, but it was either that or a huge compromise in fit, so I decided to take the plunge.
