Industrial Beauty

Raw and Refined
This bike wears its heart on its sleeve. The raw-steel finish is the star, showcasing the honest craftsmanship of the frame, complete with the unique color variations from the TIG welding process. See how this industrial canvas makes the vibrant, anodized red hubs pop with an electrifying flash of color. It's a look that is both rugged and refined, a machine that celebrates its own construction and is guaranteed to be unlike any other bike on the rack.
Two Ways to Ride
Your Ride, Your Choice
The heart of the Core-Line is its versatility, all thanks to the flip-flop hub. Want to feel every nuance of the road? Ride it fixed. Sense the unbroken chain of motion as your legs become one with the machine, a rhythmic pulse connecting you to the pavement. Prefer a more relaxed journey? Simply flip the wheel and enjoy the carefree glide of a classic single-speed. It’s two distinct, incredible ride-feels in one simple, elegant package.
