"There is an app for that". Really, you can get an app that measures angles using your smart phone or tablet. Hold it up against the seat tube and again on the front of the head tube to see what the angles are.
Since you have a pretty good side shot, i can measure from here (using the bottom of my monitor as a level reference)
Head tube angle 66.3 degrees
Seat tube angle 72.6 degrees
in the catalog shot:
head tube 70 degrees
seat tube 70 degrees
Yeah, as the bike sinks in to the ground, the head tube lays back and the seat tube tilts forward.
Pretty good eye there Wildcat. I've seen plenty of girls frames and girl back tandems bend mid-seat-tube but never noticed any like this bike.
An easy test for a bent seat tube is to put a straight edge against the rear of the seat tube near where the upper down tube meets and look for a gap. After that is straightened out, a second seat post pushed all the way to the bottom of the seat tube will reinforce the frame.
We have a tandem with a bent ladies rear at the local coop. The other mechanic brought in a screw jack of his own making to straighten out the frame. I'll try to get a photo tomorrow.
Many girls bikes have an extra tube in the frame. A stubby bit between the down tubes. I suppose this is why. See this photo for an example. That probably added $0.50 to the manufacturing cost.
