I'm 99% sure that's an electric bike. Definitely not the same as cycling a regular bike - significantly less effort involved. If she was seeing stars like I was in labour then she'd have been seriously injured.
I hope this doesn't turn into some new form of competition for expectant/new mothers..which results in women feeling guilty because they took a car.
What she's done is akin to women who don't put on weight during pregnancy thinking they've done something amazing (ie not like those other women who got "fat"), or the ones who "managed to have a natural delivery" aka did what women have been doing since humans inhabited the planet, but implicitly imply they're better than someone who had a c-section or used epidural, because what they did is an achievement.
Good for her for getting herself to her preferred delivery location before giving birth. I hope her political achievements are more significant.
