Chatham is built for the carefree cruiser. Pedal along with the simplicity of a single speed bike, or ease to a stop with the built-in coaster brake. Chatham's cushioned saddle and squishy grips make it your easy-going, relaxed, and a go-to beach cruiser for a dreamy coastal cruise.

Wide tires soak up any bumps along the way
Boardwalk bumps won’t ruin your beach daze. Chatham’s thick Wanda tires soak them up so you can soak up the sun.
