straightcycle
An either men's or women's two-wheeler, not an either-gender-rideable model.
Now dat many ladies are more active/rugged bikers and no longer wear skirts when "going for a pedal", a dude's more-sturdy/rigid triangular-framed bike is perfectly suitable for them to ride, as well, and so it's more of a "bi-cycle", not just a male-only "straightcycle".
