the aerodynamics of the seat help with performance, duh
Once ones butt is sitting on it there is nothing aerodynamic about that seat whatsoever...lol....You are just a big wind sail sitting on top of a bike is all...lol.
Reminds me of the time that someone pointed out that my motor on my bike was mounted too high and would ruin the center of gravity...The 2 cycle motors only weigh between 20 to 24 pounds......Exactly how much center of gravity does a bicycle with a motor strapped to it actually have???
The bike itself with everything on it along with tools, etc, weighs in at 80 pounds, and then my 217 pounds of lard butt enveloped over the extra wide seat, so how much COG is there???...ZERO, NADA, NONE...lol...lol.
