This didn’t even cross my mind when I saw the ad, and now I’m mad at myself for missing it! But you’re right on the money. No sexy outfits or anything of the sort. No indication that she was excited to receive the bike for any reason other than her own desire to have one. So it does sound like a lot of the outrage is rooted in the presumption that a man would only ever buy his wife an exercise bike if he wanted her to lose weight. Although as you point out, it’s an understandable presumption given the fitness industry’s track record on this subject.
