I suppose it depends if one is riding solo or with a group, or if she sees sweaty cycling clothes and wonders if he went for a ride????

One could, of course, get a bike camera with audio. Stream it, and archive onto a large external HDD. Let her review any ride she wishes. It could get boring mighty quickly.

Or, perhaps she is jealous of not being able to ride, or jealous of other riding buddies for doing "her sport", either M or F.
