Performance

Dual-motor power

2 × 1000W motors
Front and rear 1000W motors deliver strong acceleration and responsive all-wheel-drive performance. Enhanced traction provides more confident power delivery on climbs and changing terrain.

High-speed performance

Up to 70 km/h
The G4 Ultra reaches a top speed of up to 70 km/h under suitable conditions. Its dual-motor setup provides smooth, responsive acceleration across multiple riding modes.

Long-range capability

Up to 80 km
The 60V 20Ah · 1200Wh battery provides up to 80 km of range in ECO mode. Three riding modes let riders balance range and performance according to each journey.

5A fast charging

Approx. 5–6 hours
The upgraded 67.2V 5A charger reduces charging time to approximately 5–6 hours. Faster charging means less downtime between longer rides and daily adventures.

KuKirin G4 Ultra FAQs

1. What makes the KuKirin G4 Ultra different from the standard G4?

The G4 Ultra introduces dual 1000W motors instead of the G4's single-motor configuration, providing all-wheel-drive traction and a different power delivery. It also combines a 60V 20Ah battery, up to 80 km claimed range and 5A fast charging for a more performance-focused riding experience.

2. Who is the KuKirin G4 Ultra designed for?

The G4 Ultra is designed for riders who want dual-motor performance, long-distance capability and faster charging in one platform. Its combination of high power, large tyres and suspension makes it particularly relevant for longer recreational rides and varied terrain.

3. What is the difference between ECO, SPORT and RACE modes?

The three modes allow riders to balance efficiency and performance according to the journey. Claimed range is up to 80 km in ECO, approximately 50 km in SPORT and approximately 35 km in RACE, showing the trade-off between higher performance and battery endurance.

4. How does the dual 1000W motor system benefit the G4 Ultra?

A 1000W motor drives each wheel, providing stronger acceleration and improved traction when additional performance is required. Dual-wheel drive is particularly useful for climbing and maintaining traction across changing or more demanding surfaces.

5. How quickly can the KuKirin G4 Ultra be charged?

The G4 Ultra comes with a 67.2V 5A fast charger, reducing charging time to approximately 5–6 hours. Faster charging is particularly useful for riders who regularly make longer journeys and want less downtime between rides.

6. Is the G4 Ultra suitable for long-distance riding?

Yes. Its 60V 20Ah · 1200Wh battery provides up to 80 km of claimed range in ECO mode under specified conditions. Riders can switch to SPORT or RACE when additional performance is needed, although these modes will reduce the available range.

7. What advantage do the 11-inch tubeless tyres provide?

The 11-inch tubeless tyres provide a larger contact area and help create a more stable, planted riding feel. Combined with front and rear spring suspension, they make the G4 Ultra better suited to longer journeys and varied road surfaces.

8. How is the G4 Ultra equipped for higher-performance braking?

The G4 Ultra uses 160mm front and rear disc brakes with motor power-cut braking. This setup provides braking control from both wheels and immediately interrupts motor power during braking for more predictable deceleration.

9. What is new about the G4 Ultra cockpit and display?

The G4 Ultra features a redesigned stem with a large 294 × 42mm integrated display. The wider interface keeps important riding information clearly visible while giving the cockpit a cleaner and more modern layout.

10. Why choose the KuKirin G4 Ultra?

The G4 Ultra stands out by combining dual 1000W power, a 1200Wh battery, three performance modes and 5A fast charging rather than focusing only on maximum speed. It is particularly suited to riders who want strong dual-motor performance while retaining useful long-range capability and shorter charging times.
