GD8: Integrated Motor-Gearbox Powertrain

The GD8 is a compact, high-performance powertrain that unites an 8-speed gearbox and a mid-drive motor in a single, fully integrated unit. With a wide 480% gear range, 250W continuous power (600W peak), and smooth electronic shifting under load, the GD8 delivers an exceptional riding experience with minimal maintenance.

Designed to eliminate the compromises of derailleur systems, the GD8 offers robust, reliable performance in a sealed, low-maintenance format. At just 4.5 kg, it fits EP8-compatible frame mounts and supports belt or chain drives with a 58mm chainline.

Built for longevity, the GD8 is also repairable, serviceable, and manufactured using low-embodied CO₂ processes. Its in-house developed motor and UK-based production make it a compelling solution for bike brands and OEMs seeking a technically advanced, integration-ready drivetrain platform.
