If you have two inches of subcutaneous fat (I'm not assuming you do, I'm just saying if), no amount of muscle will show through. Also, muscle size and bulk is partly determined by genetics. I lifted weights pretty heavily for years, but never could develop impressive pecs--I was strong, but not showy.
Just keep riding, and reduce your body fat to a reasonable level if it isn't already. Some heavier resistance work (heavier than cycling, like squats or extensions on a weight machine) may help by increasing the size of the muscles, too.
Thank you for the help. I am just looking really to trim about a 1/2cm of fat on my stomach and bottom of my legs. The rest of my leg are very defined but not the lower thigh. Also, I have a little big of extra fat I can't seem to get rid of off my stomach. I have the abs built I know it from running and cycling (I can feel them defined) but the fat is covering it. I was just trying to find out "What I am doing wrong from not losing that fat in those spots."
