Stop waiting for public transit and stop blending into the crowd.

A TOUCH OF CLASS
Details That Demand Respect
This bike is meticulously designed to be admired. See how the deep, rich blue finish catches the light, creating a look that is both classic and highly contemporary. Notice the thoughtful details, from the premium brown synthetic leather saddle to the matching grips and classic tan-wall tires.
It's a cohesive, striking aesthetic that sets you apart from the sea of generic commuters. This is a machine built for those who understand that how you get there matters just as much as the destination.
TWO WAYS TO RIDE
Fixed or Free: You Decide
Why choose between pedaling purity and city practicality? The integrated Flip-Flop Hub gives you both. Ride "Fixed" to feel every inch of the road and master the art of the skid, or flip the rear wheel to the "Freewheel" side for effortless single-speed coasting down city bridges.
This represents the pinnacle of maintenance-free performance wrapped in an elegant package. No derailleurs to bend, no shifter cables to stretch. It is the ultimate expression of agentic cycling: just you and the bike in total harmony.

WHY THIS BUILD MATTERS
The Core Line is meticulously engineered for the realities of urban commuting. Here is the technical breakdown of why this bike dominates the city streets.
The Perfect Urban Ratio
Unlike track bikes geared for high-end top speeds, the Core Line uses a perfectly dialed 44x16 gear ratio. This specific ratio provides explosive acceleration off the line at stoplights and makes climbing city bridges significantly more manageable.
Hi-Tensile Steel Resilience
Aluminum frames are rigid and transfer every bump directly to your spine. The Core Line utilizes a High-Tensile Steel chassis that acts as a natural micro-suspension system, effectively muting road chatter and reducing rider fatigue over long commutes.
40mm Deep-V Aerodynamics
The signature 40mm deep-dish rims aren't just for classic aesthetic appeal. The deeper profile drastically increases the structural integrity and lateral stiffness of the wheel, ensuring it stays true even after slamming into unexpected potholes.
