at least the photo is a pretty straight on side shot, so if you can find out the wheel base measurements (hub to hub) you can at least get an idea of the scale of the rest of the bike and the space within the frame.
If I am not mistaken, Cranbrooks have a similar lower crossbar like that bike. Maybe talk to some people who own those and get some frame measurements from them.
If all else fails, see what their return policy is, though having to deal with shipping a bicycle BACK to someone would be a hassle
