This PanierCyclo created by Gaël Viez and Jean-Luc Pielawski helps you steer away from the plastic bag habit while ditching the need to use your car for your errands. You can transport wine, food or any other stuff that you need with it.
I like that it is easy to carry and permits you to secure it on your bike. It makes me feel like I am in France, picking up some wine, cheese and croissants.
Simple + chic = commuter superstar.
