Professional Cyclists: Elite professional cyclists can produce power outputs of 300 to 400 watts during races, with peak efforts exceeding 1,000 watts for short bursts (like sprinting).
Time Trials and Climbs: During time trials or climbs, trained cyclists can maintain higher power outputs for extended periods, often around 350 to 450 watts for well-trained athletes.
But then it tells me 40km/h assuming 400W which is obviously wrong. I guess you'd have to model that "tandem" in CAD and simulate the airflow to get accurate drag numbers
Scientifically speaking yes. Also trains
