Engineering Power Without Wires
Every revolution begins with a question. For us, it was simple: What if copper didn’t need to be wound into coils to generate power?
That single question led to the creation of BilletFlux™ - Blacksheep Power’s patented motor system built for the next generation of high-performance electric motorbikes.
Instead of using conventional wire-wound stators, BilletFlux™ transforms CNC-machined solid copper into perfectly aligned electromagnetic fields - engineering power without wires.
A New Kind of Motor Engineering
Traditional electric drive systems waste space and heat in complex windings. Our BilletFlux™ changes that by ensuring every millimetre of copper contributes directly to propulsion efficiency.
From the first experimental cuts in 2023 to a road-ready prototype delivering 700 Nm of torque, 35 kW peak power, and sub-5-second acceleration to 100 km/h, BilletFlux™ evolved through three generations of precision engineering.
From Concept to Power System
1 - First Generation - Air-Core Concept
- EDM-machined copper billets
- Air-core architecture
- Structure separated from conductor pathways
This stage proved the concept of winding-free power generation and set the foundation for real magnetic control.
2 - Second Generation - Magnetic Focus
- Laminated silicon-steel core
- Integrated cooling concept
- Enhanced field alignment and torque response
This phase brought BilletFlux™ closer to scalable production and performance stability.
3 - Third Generation - Full Integration
- CNC-machined copper billets
- Soft Magnetic Composite (SMC) core
- Carbon-fibre stator plate and fully integrated cooling
These were the stator architectures that shaped our journey toward The Blacksheep ONE - each a step forward in power, precision, and cooling. The version debuting at Motorcycle Live 2025 is the next evolution - a fully refined system built on everything we learned along the way.
Why It Matters
BilletFlux™ isn’t just a new motor design. It represents a shift in how power, precision, and cooling can coexist inside an electric motorbike. When paired with our BilletFlow™ and BilletPower™ systems, it forms a seamless chain of innovation - where engineering is visible, not hidden.
