Just signed up to the forums.
Am 49, male, and have been riding regularly since April of this year. Prior to that maybe one or two miles per year.
What got me going was the need to get fit after a heart attack. Now I try to get about 25 miles per week, although winter has cut that back some.
I found the forums while researching for a good stationary bike to use until spring arrives. I am now thinking about trying to bike outside in the snow and ice.
