The high-performance electric scooter market has evolved rapidly, with riders moving beyond basic urban commuter models in search of true all-terrain capability, rapid acceleration, and longer range. KuKirin has consistently delivered on these demands, and our latest release—the KuKirin G4 Ultra—marks a significant leap forward in performance engineering.
Combining raw dual-motor power with smart features like an ultra-wide touch screen cockpit and high-speed fast charging, the KuKirin G4 Ultra bridges the gap between rugged off-road machines and refined daily commuters. Below, we examine what makes this new Flagship scooter stand out, followed by a comprehensive specification comparison against its predecessors: the single-motor KuKirin G4 and the mid-tier KuKirin G2 Ultra.
1. Deep Dive: Key Features of the KuKirin G4 Ultra
Unmatched Power & Traction: Dual 1200W Motors
While standard scooters struggle on steep gradients or loose surfaces, the KuKirin G4 Ultra is powered by dual 1200W brushless motors operating on a 60V architecture. Delivering over 30 N·m of peak output torque per wheel, this dual-drive setup gives you dynamic all-wheel traction. Whether tackling steep 30° inclines, cobblestone city streets, or wet pavement, the G4 Ultra propels riders to a maximum top speed of 70 km/h (43.5 mph) smoothly and predictably.
| KuKirin G4 Ultra At A Glance | |
|---|---|
| Peak Speed | Up to 70 km/h (3 Speed Modes: 20 / 40 / 70 km/h) |
| Motor Power | Dual 1200W Motors (60V Architecture) |
| Maximum Range | Up to 80 km (60V 20Ah / ~1200Wh Battery) |
| Fast Charging | 67.2V 5A Charger Included (Full Charge in 5-6 Hrs) |
| Tires & Braking | 11-Inch Tubeless Tires + Dual 160mm Disc Brakes |
| Frame & Display | Reinforced Aluminum Chassis + 294x42mm Touchscreen |
High-Capacity 60V 20Ah Battery & 5A Fast Charging
At the heart of the G4 Ultra lies a heavy-duty 60V 20Ah lithium-ion battery (1200Wh), providing an impressive cruising distance of up to 80 km on a single charge in Eco mode.
One of the biggest pain points with large-capacity electric scooters is long charging times—often taking 10 to 12 hours. KuKirin addresses this directly by bundling a 67.2V 5A fast charger out of the box, slashing full charge times down to just 5 to 6 hours.
All-Terrain Comfort: 11-Inch Tubeless Tires & Dual Spring Suspension
To handle high speeds comfortably, the G4 Ultra relies on 11-inch widened tubeless off-road tires. These larger-diameter tires provide a wider contact patch for superior cornering grip while drastically lowering the risk of pinch flats. Combined with dedicated front and rear spring suspension systems, the scooter easily absorbs road vibrations, potholes, and terrain bumps.
Futuristic Cockpit: Integrated LED Touchscreen & Audio
Dominating the handlebar setup is a massive 294 × 42 mm integrated LED touchscreen display. Replacing clunky, traditional small displays, this ultra-wide panel displays live speed, trip telemetry, battery levels, turn signals, and ride modes at a glance.
Additionally, built-in Bluetooth speaker integration allows you to connect your smartphone for audio playback or system navigation alerts on the go.
Upgraded Safety & Heavy-Duty Frame
- Reinforced Folding Stem: Redesigned heavy-duty locking mechanism minimizes stem flex and ride chatter at higher speeds.
- Dual 160mm Mechanical Disc Brakes: Paired with an electronic motor power cut-off safety switch to ensure rapid stopping distances (8–12 meters).
- Comprehensive Lighting: Bright LED headlights, integrated brake lights, ambient deck lights, and turn signals improve visibility during night rides.
- Weather Resistance: IPX4 rating for the entire body, with key electrical assemblies engineered to IPX6 (motor) and IP55 (battery enclosure) protection standards.
