Have you considered that the glorious day featured in the ad is for aesthetics and mental association, and not actually representative of when most people use their stationary bikes?

I try to get out on the trail when I can, but not all of us live in locations where regularly getting on a real bike is compatible with having a full-time job. Between sunrise/sunset times and weather, in the Seattle area you're going to have to be quite dedicated to get on a real bike 3-4 times a week year round.
