Aero test result (informal, unscientific)
Just did an aero experiment (not scientific). Today the wind is blowing steady at 6mph straight up a river bike path near my home on my commute. The path is flat, straight, and in great shape. I decided to informally ABABAB test my aero tuck. In calm conditions I get a little over 22 mph (approx) electric only, full throttle. I wound the throttle out and got to 20.3 MPH (approx). Then I tucked in close the the handle bar, pulled hands, elbows, and knees in, and got to 21.8 (approx). I did this over and over for probably a mile or more.
Result: I kept seeing approximately a 1.5 mph difference between upright and fully tucked position. That almost a 7% difference,
This is noticeable but not as significant as the article suggests. Reasons for that might be the wind gusts of up to 10 mph somehow messing with the results or especially the loaded pannier behind me on one side. A loaded pannier would make whatever I do up front less significant, I would bet.
