I am always startled by the huge size of bicycles relative to their riders in photos from around the turn of the century. I wonder if riding gigantic "safety" bicycles was a holdover from the days of riding high wheels? Notice especially the PBH (pubic bone height) of the guy on the left relative to the top tube of his bike. If either of these guys ever had to come down off the saddle in a hurry, I bet they were wishing they had smaller frames.
