Health! Nature! Saving money!
It doesn't really matter which of these reasons is right, Tim Robbins is riding his bike and it looks like he might just simply be enjoying it (Kinda? Maybe that's strain on his face?)!
Plus, we're pretty sure you can't go to a place called the Green House Smoke Shop and NOT be eco-friendly!
We wonder what he purchased…
Looking fab, Tim! Keep up the healthy choices!
