The combination of dual motors, battery capacity, large tires and multiple braking systems is what defines the overall package.
Dual 1000W Motors: Power on Demand
At the heart of the G4 Ultra is a dual-motor system with two 1000W motors.
That gives the scooter a total motor rating of 2000W.
Dual-motor configurations can provide a different riding experience from single-motor scooters.
Instead of relying on one motor to deliver all the drive force, the G4 Ultra distributes propulsion across both wheels.
This can be particularly useful when riding on:
- Inclines
- Uneven roads
- Longer routes
- Surfaces where additional traction is useful
- Routes where stronger acceleration is desired
The result is a scooter designed for riders who want a more substantial performance experience.
Up to 70 km/h: Built for High-Performance Riding
The KuKirin G4 Ultra reaches a claimed maximum speed of 70 km/h, making it one of the high-performance models in the KuKirin lineup.
Rather than having only one riding setting, the G4 Ultra provides three speed levels:
20 km/h → 40 km/h → 70 km/h
This gives riders the ability to select a suitable speed level according to the riding environment.
Lower speed settings can be useful for controlled riding in appropriate areas, while higher settings are designed for situations where the conditions and applicable regulations permit them.
Ride According to the Conditions
A high maximum speed does not mean that riders should always ride at maximum speed.
Road surface, traffic, weather, visibility and local regulations should always be considered.
For public-road use, riders should check the laws and requirements that apply in their country or region before using a high-speed electric scooter.
60V 20Ah Battery for Long-Range Riding
Power needs energy.
To support its dual-motor system, the G4 Ultra is equipped with a 60V 20Ah battery.
The scooter has a claimed maximum range of up to 80 km.
That gives riders more flexibility when planning longer journeys and reduces the need to think about charging after every short trip.
A larger battery can be particularly useful for riders who want to use their scooter for:
- Longer recreational rides
- Extended urban journeys
- Multi-stop trips
- Weekend exploration
- Regular longer-distance transportation
Of course, actual range will vary depending on riding speed, rider weight, terrain, temperature, wind, road conditions and riding style.
In particular, riding at higher speeds generally consumes more energy than riding at lower speeds.
5–6 Hours Charging Time
Despite its large battery capacity, the G4 Ultra has a listed charging time of approximately 5–6 hours.
For riders who plan their charging around their daily routine, this means the scooter can be recharged during an extended break or overnight.
A practical charging routine can also help ensure the scooter is ready when you need it.
Always follow the charging instructions supplied with the scooter and use the appropriate charger.
11-Inch Tires for a More Substantial Ride
The G4 Ultra uses 11-inch tires, giving the scooter a larger contact setup compared with many compact electric scooters.
Larger tires can contribute to a more planted riding feel and can help the scooter handle changes in road surface more comfortably.
They can be useful when riding across surfaces such as:
- Urban pavement
- Rougher roads
- Uneven sections
- Lightly broken surfaces
- Longer-distance routes
However, tire size is only one part of the handling equation.
Tire pressure, road conditions, suspension, rider input and overall scooter design all influence the final riding experience.
Braking System: Front and Rear Disc Brakes
With a scooter capable of reaching a claimed 70 km/h, braking performance is an important part of the overall design.
The G4 Ultra uses front and rear disc brakes, providing braking at both ends of the scooter.
This is complemented by front and rear power-cut brakes.
The combination gives the G4 Ultra a braking system designed around both mechanical braking and electronic motor cut-off.
Why Power-Cut Braking Matters
A power-cut brake system is designed to interrupt motor power when the brake is activated.
This means braking and motor output work together rather than operating independently.
For a performance-oriented scooter, this can contribute to a more controlled braking experience.
Riders should still allow enough stopping distance and adjust their speed according to the road and surrounding conditions.
120 kg Maximum Load
The G4 Ultra has a listed maximum load of 120 kg.
Maximum load capacity is important because it includes more than just the rider's body weight.
When considering load, riders should also account for items such as:
- Backpack
- Protective equipment
- Personal belongings
- Other carried items
Staying within the manufacturer's specified load limit is important for maintaining the intended performance and handling characteristics.
IPX4 Water-Resistance Rating
The G4 Ultra has an IPX4 waterproof level.
This indicates a level of protection against water splashes from different directions under the conditions covered by the rating.
However, IPX4 does not mean the scooter is waterproof in every situation.
It should not be submerged in water or intentionally exposed to heavy water flow.
After riding in wet conditions, allow the scooter to dry properly before charging or storing it.
43.4 kg: A Performance Scooter With Substantial Weight
The G4 Ultra has a listed net weight of 43.4 ± 0.5 kg.
That's a substantial weight compared with lightweight commuter scooters.
But the weight is also a reflection of the hardware required for a high-performance dual-motor scooter with a large battery, large tires and a comprehensive braking system.
For potential buyers, this is an important consideration.
The G4 Ultra is designed more around riding performance and long-range capability than ultra-portable commuting.
Before purchasing, think about where you will store the scooter and whether you need to regularly carry it up stairs or load it into a vehicle.
Who Is the KuKirin G4 Ultra For?
The G4 Ultra is aimed at riders who want more than a basic commuter scooter.
It may appeal particularly to riders looking for:
Dual-motor performance
Two 1000W motors provide the foundation for a powerful riding experience.
Long-range capability
The 60V 20Ah battery and claimed range of up to 80 km support longer rides.
High-speed capability
The claimed 70 km/h maximum speed provides a performance-oriented option where legally permitted.
Large tires
11-inch tires contribute to a substantial and stable riding setup.
Enhanced braking configuration
Front and rear disc brakes are combined with front and rear power-cut braking.
G4 Ultra vs Everyday Riding
A high-performance scooter doesn't necessarily need to be used for high-speed riding all the time.
The three speed levels—20 km/h, 40 km/h and 70 km/h—give riders different settings for different situations.
For example, a lower speed setting may be more appropriate for controlled riding in a suitable environment, while higher settings may be reserved for locations where they are legally permitted and conditions allow.
This flexibility makes the G4 Ultra more than a single-purpose performance machine.
What Makes the G4 Ultra Different?
The most important point about the G4 Ultra is not any single specification.
It's the combination of several high-performance components:
2000W dual motors
60V 20Ah battery
Up to 80 km claimed range
70 km/h claimed maximum speed
11-inch tires
Front & rear disc brakes
Front & rear power-cut brakes
Together, these specifications create a scooter aimed at riders who want a more powerful and substantial electric scooter experience.
