KuKirin G4 Ultra First Look: Dual 1000W Motors Take Performance Further
The KuKirin G4 Ultra has officially launched — and it is not simply an upgraded G4.
It is a completely different performance platform.
Where the G4 uses a single 2000W motor, the G4 Ultra takes a different approach entirely: two 1000W motors working together. The result is a scooter that delivers power differently — not just more, but smarter.
This first look covers what is new, what is different, and who the G4 Ultra is really built for.
Core Specifications

G4 vs G4 Ultra: A Different Kind of Power
<img src="your-image-url.jpg" alt="KuKirin G4 single motor vs G4 Ultra dual motor power comparison">
This is the most important difference to understand.
The standard G4 uses a single 2000W motor driving the rear wheel. It delivers strong acceleration and a 70 km/h top speed, but all the power goes through one wheel.
The G4 Ultra uses two 1000W motors — one in each wheel. This changes everything:
Dual motor advantages:
-
Better traction — power is distributed across two wheels, improving grip on loose or wet surfaces
-
Faster response — two motors react more quickly than one large motor
-
Better hill climbing — the front motor pulls while the rear pushes
-
More stable at speed — the scooter feels more planted and balanced
This is not about raw power alone. It is about how the power is delivered.
Three Riding Modes: Range vs. Speed
The G4 Ultra offers three distinct riding modes, each with a different balance of speed and range.
ECO Mode — 20 km/h, up to 80 km range
Designed for maximum efficiency. Ideal for long commutes where range matters more than speed. In this mode, the G4 Ultra can travel up to 80 km on a single charge.
SPORT Mode — 40 km/h, up to 50 km range
The everyday riding mode. A balance of speed and efficiency that suits most urban and suburban journeys. Delivers up to 50 km of range.
RACE Mode — 70 km/h, up to 35 km range
Full performance. Both motors at maximum output for the highest speed. Range drops to approximately 35 km in this mode — the price of maximum performance.
The takeaway: The G4 Ultra gives you the choice between long range and high speed. You are not locked into one or the other.
Design Upgrades

The G4 Ultra introduces several design improvements over the standard G4.
New stem design — A redesigned front stem that improves rigidity and steering feel at high speed.
Large display — A 155×55mm LED touchscreen showing speed, battery level, mileage, cruise control, riding mode, and more. The layout is clearer and easier to read while riding.
Bluetooth audio — The G4 Ultra supports Bluetooth connectivity, allowing you to pair your phone for audio and app-based features.
Dual cantilever suspension — Front and rear suspension with a double cantilever design, providing more progressive absorption than standard springs.
Full lighting system — LED headlight, taillight, brake light, and turn signals.
Who Is the G4 Ultra For?

The G4 Ultra is not for everyone. It is for riders who want more than just top speed.
You should consider the G4 Ultra if:
-
You want dual-motor traction for better grip and stability
-
You ride on mixed surfaces — gravel, wet roads, or uneven terrain
-
You value fast acceleration and responsive power delivery
-
You want the option of long range (80 km) or high speed (70 km/h)
-
You are an experienced rider looking for a more complete performance package
The G4 Ultra may not be for you if:
-
You need maximum range at maximum speed (physics limits apply)
-
You prefer a lighter, more portable scooter
-
You are a beginner rider — 70 km/h requires experience
-
You do not need dual-motor capability
Frequently Asked Questions (FAQ)
Q1: What is the main difference between the G4 and G4 Ultra?
The G4 has a single 2000W motor. The G4 Ultra has two 1000W motors — one in each wheel. This provides better traction, faster response, and improved hill climbing, rather than just more raw power.
Q2: How fast does the G4 Ultra go?
70 km/h in RACE mode. In SPORT mode it reaches 40 km/h, and in ECO mode 20 km/h.
Q3: What is the range of the G4 Ultra?
Range depends on the riding mode:
-
ECO (20 km/h): up to 80 km
-
SPORT (40 km/h): up to 50 km
-
RACE (70 km/h): approximately 35 km
Q4: How long does it take to charge?
The G4 Ultra uses a 5A fast charger and charges in 5–6 hours — faster than most scooters in its class.
Q4: Is the G4 Ultra legal on public roads?
The G4 Ultra reaches 70 km/h, which exceeds the legal speed limit for e-scooters in most European countries. Always check your local regulations. It is best suited for private land or areas where higher speeds are permitted.
Q6: What tyres does the G4 Ultra use?
11-inch tubeless tyres (90/55-7.5) with a recommended pressure of 340 kPa (50 psi).
Q7: Does the G4 Ultra have a seat?
No — the G4 Ultra is a standing scooter. It does not include a seat.
Conclusion: More Than Just a Speed Upgrade
The KuKirin G4 Ultra is not defined by a single number. It is defined by how it delivers performance.
Dual motors. Three riding modes. Up to 80 km range or 70 km/h speed — your choice. A new stem, larger display, and Bluetooth connectivity.
This is not just a faster G4. It is a different scooter entirely — built for riders who want more control, more traction, and more flexibility.
If that sounds like you, the G4 Ultra is worth a closer look.
