[TenTec] OT

[d.e.warnick at comcast.net]

They now have power hubs for bicycles. Serious riders measure their output in watts and train to do better, or to keep their output (watts) consistent. 



That said, my son owns a bike shop catering to competetive sports. Just talked to his partner who is in his 30's and extremely fit. Average power for a guy like that riding down the road is 150 to 200 watts. A sudden burst of 1000 to 1200 watts is possible, but we're talking 10 seconds or less. 



So all we need to do is regain our youth, lose the fat, train hard and we can keep our buddy keying an Argonaut 5

200 w out with everything else included including efficiency works out to 
getting close to a half horsepower - probably not too difficult for a 
healthy horse - but one person?  K3TX
