About us

Cosmic Bikes is a full-service brick-and-mortar bicycle store located on the Chicago's NW Side in Jefferson Park.

We carry bikes that will take you Downtown and out of town, around the neighborhood, and around the world. Bikes for where pavement ends and adventure begins, bikes you can pack in a suitcase and take on a plane, bikes for anywhere you want to go.

Let us help you find a bike that will fit your body and your lifestyle, delight you, offer you years of enjoyment, and make you want to get out there!
