The KuKirin G4 Ultra evolves the G4 performance platform with dual-motor drive, a redesigned stem, a larger integrated display, 5A fast charging and smarter protection. It is not simply about more power – it is about better power.

The KuKirin G4 Ultra evolves the G4 high-performance platform with front and rear 1000W motors, a 60V 20Ah battery, 70km/h capability and 11-inch tubeless tires. A redesigned stem, large 294×42mm display, 5A fast charging and temperature protection turn raw performance into a more refined riding experience.

The KuKirin G4 Ultra is not designed simply to make the numbers bigger. It evolves the direct, powerful character of the G4 into a more complete and refined performance experience.

Front and rear 1000W motors deliver stronger launch response, greater mid-range acceleration, more confident climbing performance and additional traction under load. The value of dual drive is not only top speed – it is having both wheels contribute when more power is needed.

A 60V 20Ah battery provides approximately 1200Wh of energy. Under specified test conditions, range reaches up to 80km in ECO, 50km in SPORT and 35km in RACE mode, allowing riders to choose the balance between distance and performance that best fits the journey.

The 11-inch tubeless tire platform, front and rear spring suspension, and front/rear 160mm disc brakes create a stable chassis foundation. Large wheels support higher-speed stability and road-surface adaptability, while the suspension helps absorb impacts and the braking system provides balanced deceleration.

The Ultra experience also appears in the details riders use every day. A redesigned stem gives the scooter a sharper, more mature stance. The 294×42mm integrated display makes speed, battery and riding information easier to read, while the 67.2V 5A charger reduces charging time to approximately 5–6 hours.

Motor and battery temperature protection add another layer of system protection, while smartphone connectivity and Bluetooth audio bring additional convenience. The G4 Ultra is not just more power – it is better power.

Not just more power. Better power.
