On Friday night, Time’s Up!, the cycling and environmental group, held a “Ladies Night Dance Ride.” In honor of International Women’s Month, a gathering of female cyclists met in the twilight at Tompkins Square Park, where they performed an R-rated (for “Ride”) dance with their bikes before pedaling off to Astor Place and Union Square to repeat the performance. In some countries, the group said, women are not allowed to ride bicycles. They held the event in solidarity with women the world over in a call to get out of cars and onto bikes.
