The wind in the back seat is a major issue, even with a full face motor cycle helmet.
You hit upon the one major concern, Wayne. Though it has been told that one can wear a cap in the front seat without it blowing off. The backseat is rather breezy. In looking at the Pusher, I was thinking it wouldn't be too difficult to fabricate a windshield for the back seat. Then the light bulb flashed and duh? What would that do for the airflow for the propeller?
I know that was a real deal killer when I was considering going to a trike. All that wind in the face was very uncomfortable for me.
Thanks Wayne,
