The first of those photos is from Flickr. (It was taken and posted by Eda Cherry.)
The rest of the photos are from Bike Salute . com.
For me, those images are a mix of feminism and pro-cycling advocacy.
Of course, I mention feminism because the photos convey female empowerment — which, in this case, involves a lot more than the muscular strength needed to lift the bikes. There’s also a little pride on display, and that can be feminist — for women, and for anyone who is at odds with the sex and gender status quo (which also includes mainstream forms of take-charge and take-authority masculinity).
In other words, feminism isn’t just about women —
as I’ve previously indicated here, for instance.
