I work with someone in her 50s who wants to get back in to cycling. She's 4' 10.5". I've told her that there are women's-specific bikes that will go very small. She can't get over the thought of going into a bike shop and trying what she sees as a childs bike. Is there anything cheapish and obviously adult-oriented that she might be able to try. I don't think the smallest Carrera Subway will be small enough for her.
