Rachel Bilson bicycle basket helmet sunglasses

It's so nice to see a Hollywood star out enjoying the sunny LA weather on her bike, sans makeup, without Christian Louboutins, no fur, and no bodyguard. How refreshing!

Rachel Bilson took to the streets of Los Feliz for a little spin on her bicycle Saturday and while she remove her helmet to pose for some pix (natural AND nice!), worry not ... the starlet observed bike safety. See her helmet style after the jump.
