It's the power to the back wheel that do fight that wind resistance.

And the trainers do simulate both wind resistance and inclination. One of them with fan + magnetic break. One with a computer-controlled motor/generator.

The question is what you mean by "hit 480 Watts". A fraction of a second, or 5 seconds or leaving the field to claim that sprint price?

With two different simulations about 300-350W has been my limit what I have been able to do for an hour without accumulating lactic acid. Switching to interval training, I have done 5 min intervals at about 420 W with 10 min cooldowns.

Translated to outdoors, that 300-350W trainer load have been similar in effort to averaging about 42km/h on an older Nishiki racer (costing probably less than one of the wheels you linked) while alone doing the road in both directions - 30km in about 42 min.

I don't think the trainer figures are too far off from real loads. Which, alas, makes it quite hurtful to get on that trainer now after having been off the bike for about 6 years because of a knee injury. I think I have to hack the trainer to multiply my speed with 1.2 or 1.3 to feel a bit better :)
