Gearbox Powertrain

Cars have a gearbox that lasts the life of the car. Bikes rely on exposed external gearing that wears out and is easily damaged.
The GD8 puts the motor and an 8-speed gearbox in one sealed unit, designed to last the life of the bike with just an occasional oil change.

Electronic Shifting

Ultra fast, consistent gear changes in any condition - under load, pedalling, not pedalling, even when stationary! Our patented electronic shifting technology sets a new standard for e-bike performance.

Circular by Design

We create high-performance products with purpose, designed for longevity and repairability. We're committed to providing spare parts for the long term, and the majority of our European supply chain is powered by renewable electricity.
