No, I don't agree. I'm only talking about the actual useful power. The power required of an engine were it to replace Robbie...
If we go into total power for the body, we have to multiply the power figures by five, as the cycling efficiency for the body is about 20-21%. However, that only scales the numbers up, but the ratio doesn't change.
About 300 W is the endurance power level for pros at his level, and they're not riding solo for hours at 65 km/h, which would surely be the case if 240 W was sufficient to go 60 km/h...
