About Us

01

Mission & History

CY:ONS was born from a simple, stubborn question: Why should one bike only serve one purpose? As cities grew more complex and the climate crisis accelerated, we saw an urgent need for mobility solutions that didn’t force people to choose between performance, flexibility, or sustainability.
 

What started as a series of sketches in a workshop has grown into a cross-disciplinary company pushing the boundaries of what bikes can be. Our first challenge? Build a bike that could transform, stretch to carry more, shrink to store better, and connect digitally to support both riders and cities. 
 

What sets us apart is our refusal to compromise. We do not believe in disposable design. Every product we create is meant to grow with you, physically and functionally. We integrate engineering with empathy, and technology with timeless design.
 

We exist to empower people and cities with vehicles that adapt, so individuals can own less, do more, and move smarter. At CY:ONS, we put users first by designing from real-world needs, prototyping in-house, and listening closely to everyone from city commuters to delivery riders to families.
 

Our mission is simple: Stretch mobility beyond its current limits.
Our values are clear: Ingenuity, adaptability, and impact.
Our vision is bold: A future where every movement is smarter, more personal, and more sustainable.
