The world’s lightest E-bike conversion kit — featuring the stealthiest thru-axle rear hub motor, built for lightweight, high-performance bikes.

Weighing just over 1kg for the complete system, it pairs a thru-axle rear hub motor with a modular bottle battery and an aerodynamic carbon fiber rim — preserving your bike’s original aesthetics.

Multiple assist modes let you tailor the ride to your needs, including an intelligent mode that automatically responds to your cadence, effort, and terrain. Power when you need it. Invisible when you don’t.

The patented automatic clutch ensures smooth, drag-free pedaling when the assist is off.

Both the modular bottle battery and the aerodynamic carbon fiber rim feature aerodynamically designed profiles while maintaining a clean, minimalist aesthetic.

Perfect for riders chasing an ultra-lightweight build, pure ride feel, and just the right touch of assist.
