The current bike rider position (on the diamond bike) makes riding less energy efficient, for one, and more agile - rider can more easily change direction or start sprinting or both.

All of this make bike riding sport more entertaining. I guess I can put it next to Formula 1 - low and high velocities, fast and slow turns, attacks, defense, etc.

The recumbent riding would be mostly technological and would have less action. I guess I can put it next to NASCAR - high velocities, slow turns, slow attacks.

I think that recumbent would be good for US, I also guess rest of world would prefer diamond bikes.
