When I was a lot into road cycling, my topspeed used to be about 60 km/h.
That was in an all out sprint, I do not have a power meter but the Kreuzotter calculator says 1249 W of power are required for that on my roadbike in my sprinting position.
If I went with my most agressive TT position (Superman), I'd need only 570W for the same speed.
With a fully faired recumbent I'd be at a sustainable 180W.
Aerodynamics matter a lot even at that kind of speed.
And I love to show it to road cyclists by passing them on my rather comfortable and aerodynamic recumbent.
