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

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 that's 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 ?

What do you mean? What kind of wind generator are you talking about? Here's a relatively inexpensive residential wind turbine that puts out 400w.

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