Portability

The KuKirin G4 includes a folding mechanism for easier storage and transport.

However, at approximately 41 kg, it is considerably heavier than most commuter scooters.

The scooter is best suited to riders who:

  • Store it in a garage
  • Transport it occasionally by car
  • Do not need to carry it up stairs regularly

Performance

The standout feature of the G4 is its 2000W rear hub motor.

Unlike many scooters that use smaller motors designed primarily for commuting, the G4 is built for higher speeds and stronger acceleration. The scooter offers three riding modes, allowing riders to choose between efficiency and performance.

Top Speed

The KuKirin G4 has a claimed top speed of up to 43 MPH. Real-world top speed will vary depending on rider weight, road conditions, tyre pressure, and battery charge level.

For experienced riders, the G4 offers performance that goes well beyond most entry-level or commuter-focused scooters.

Hill Climbing Ability

The G4 is designed to tackle hills more effectively than lower-powered scooters.

KuKirin rates the scooter for gradients of up to 20–30°, depending on conditions and rider weight. The high-torque motor helps maintain momentum on inclines where smaller scooters may struggle.

This makes the G4 suitable for:

  • Hilly urban areas
  • Countryside routes
  • Longer recreational rides
  • Heavier riders

Battery Range

The G4 uses a large 60V 20Ah lithium battery, providing a claimed maximum range of up to 46 Miles.

As with any electric scooter, actual range depends on several factors.

Factors Affecting Range

  • Rider weight
  • Riding speed
  • Terrain
  • Tyre pressure
  • Weather conditions
  • Frequency of acceleration and braking

Riders who regularly use the highest speed mode should expect lower real-world range than the maximum figures advertised.

Build Quality & Design

One of the most distinctive aspects of the G4 is its design.

The scooter features:

  • Large riding deck
  • Integrated display
  • Folding mechanism
  • Built-in lighting system
  • Steel and aluminium frame construction

Its robust frame contributes to excellent stability at speed while maintaining durability for everyday riding.

Ride Comfort

The KuKirin G4 is built with comfort in mind, particularly for longer journeys.

11-Inch Tubeless Tyres

The large tubeless tyres provide:

  • Improved grip
  • Better shock absorption
  • Increased stability at speed
  • Reduced puncture risk compared to tube-based tyres

Suspension System

The scooter features front and rear spring suspension, helping absorb bumps and imperfections in the road surface.

This creates a more comfortable ride than many rigid-frame scooters.

Braking Performance

When travelling at higher speeds, reliable braking is essential.

The KuKirin G4 uses:

  • Front disc brake
  • Rear disc brake
  • Electronic braking assistance

This combination helps deliver strong stopping power and improved control during emergency braking situations.

Regular brake maintenance is recommended to ensure optimal performance.
