The KOOLUX X9 Pro is powered by a 750W motor designed for stronger starts, hill support, headwinds, and heavier daily rides. With standard 25 km/h riding and unlockable higher-speed support for private-road use, it gives riders more confidence across city roads and outdoor routes.

Front Suspension Comfort
