You do the riding, Byku the computing.

Purist Performance. Byku is a minimal cycling computer for the purist. We trade complex menus for clean typography and confusion for clarity. It’s the essential data you need—Power, Speed, Time—delivered with the elegance your bike deserves.
A reduction to the essential. In a world of noisy dashboards and cluttered screens, we believe the beauty of the ride lies in its simplicity. Byku strips away the distractions, presenting your power and performance with typographic elegance and zero friction. It is a tool designed to be felt, not just read—simple on the surface, profound underneath, and completely focused on the road ahead.


Only available on Apple iPhone
Byku is exclusively available on the Apple iPhone, crafted not just to run on your device, but to belong to it. We leverage the fluidity, haptics of iOS to create an experience that feels like a natural extension of your phone. No clutter, no compromises—just a perfect fit.

„I needed a simple bike computer that does integrate power meters. But I got so much more. My whole idea of what riding a bike is changed.“
