“Ovaries so big, we don’t need no fucking balls.”

That’s the motto of the Ovarian Psychos Bicycle Brigade, a Los Angeles-based, all-women-of-color collective fighting overt and insidious violence through bike rides. Also known as the Ovas, the Ovarian Psychos are the subject of a new documentary of the same name that premiered Saturday (March 12) at Austin’s South by Southwest festival.

A new piece from LA’s KCET digs deep into the Ovas’ MO. It’s well worth reading in full, but a few excerpts about this exhilarating and devoutly progressive group showcase exactly why this documentary is important.

Even a travelling sisterhood needs a headquarters. That’s the purpose La Concha, a Boyle Heights community center covered by a rocky façade and guarded by a scarlet gate, serves for Ovarian Psycos bicycle brigade.

They are decolonizing their neighborhoods one pedal pump at a time.

The Ovas do this, in part, through group bike rides that protest violence, whether embodied in women murdered in public spaces or gentrification that threatens to erase East LA’s working-class, immigrant backbone:
