I think you've found your market. Maybe pick up as many as you can carry. Edit just looked again if you buy it and don't like it I'm interested assuming around 23"
Actually, that is a bloody good point. Did they even make these type of bikes in different sizes?
On the road bike I'm on retro modern slightly sloping top-tube at 54cm = 21 ½". 1.75m tall, which put's me in the average ball park.
