Your comment may be less funny and exagerated than you think.
On long stretches of flat dirt trail next to some fields I can maintain 20mph for a very long time while on my hybrid with cyclocross tires.
500W may sound like a lot but many people can "dial it up" to that for a short time and then recover afterwards ... pro racers go to 1500 or 2000.
