How much energy do i produce with my dynamo while cycling ?

  1. Oct 23, 2008 #1
    I was on an exercise bike in the gym the other day and on the screen it said I was generating 138 watts, and as you can imagine thats a pretty big value,lol. I wasn't cycling that fast either. My question is, is this value possible ?

    sorry if this is a bland question but I know a wind generator gets about 100 watts, so I am just trying to get my head around this. Thanks in advance.

    Yes that's reasonable for cycling.
    One horsepower is 750W, a professional cyclist can produce about 1/3Hp = 250W

    but how can this number be so much greater than a wind generator ?

    Wind farm generators are rated by mega-watts. You must be referring to a very small wind generator.
