Getting a workout on set while filming her new movie, Megan Fox rode a bike for "Teenage Mutant Ninja Turtles" in New York City on Friday (May 31).

Megan Fox wore a gray T-shirt, black jeans, and a yellow leather jacket as she strapped on her helmet and pedaled away.

Portraying beloved comic book and cartoon character, reporter April O'Neil, the 27-year-old actress joins the quartet of turtles played by Noel Fisher, Jeremy Howard, Pete Ploszek, and Alan Ritchson.

In the newest adaptation, aliens invade Earth and inadvertently spawn a quartet of mutated reptile warriors, the Ninja Turtles, who rise up against them to defend the world. "Teenage Mutant Ninja Turtles" is scheduled for release on June 6, 2014.
