The model name is printed on the top tube and no way does that look like a 19" frame.
When you straddle the top bar do the boys hit or do u have clearance? Stand over the top bar with no shoes on. Lift your toes up just a touch so all your weight is on your heels and try to bend your knees. If you can bend them you can get away with riding it. If you cant bend your knees forget it.
