Solid point olddog. Thinking I'll convert all power makers and users in my house to hp, cause I like hp better than anything else (even beer). Not too sure how much hp to assign for the wife though. I mean I can make sense of her motion and torque potential, just not educated enough to factor in the friction.

A good cyclist can produce 1.2 kW.

That's only for short bursts.
I'd be lucky to sustain 0.25kW (0.3 HP) for more than a minute. (Although I'm definitely not a "good" cyclist.)

A spri(n)ter can even go higher. My limit is also approx 250 Watt during an EEG.
But how much torque is 1 kW with a 170 mm crank on the bike? :-) (Back to the topic?)
And what role do 70 rpm play?
;-)

Yep, every Sprite I've ever driven seemed like it was putting out about a light bulb's worth of power.

1.6 Hp for Mike.
So, it's possible to go over 25 mph on a bicycle with only 1.6 Hp? Hmm... Never gave it any thought.

Actually, there are many bikes with 750 watts that will easily do that. They are usually governed to 20 mph (I think that's a law), but it's an artificial limit. A little tweaking yields over 30 mph.
