IRL, you'd have to know the context of that gift to know what implications it conveyed. If "already fit" wife had been complaining about the difficulties of getting to the gym and/or riding on the street in order to keep fit, this could have been quite a thoughtful gift to make things easier for her. If none of that is true, and he's been saying things like "you'd be really cute of you dropped a few" or "you should keep yourself to 1500 calories a day", then he's probably a jerk.
Peloton markets a really expensive product that does something that much cheaper products can do. No surprise that they'd have to come up with elaborate scenarios to get people to buy it as a gift.
