There is nothing wrong with this usually you get a good frame with solid components.Cheap seats,hadlebars,pedals and crankset. If you know your size and know what you want its a good deal.
At 5-9 you're more likely looking at around 54 cm, I'm the same height and that's what I have. However, depending on your inseam, that may be a bit higher or lower. Before buying online, your best bet is to go to a local bike shop and get measured.
