Kukirin G2 Ultra Electric Scooter Full Review: Budget Dual-Motor Performer Worth Buying?

Overview: A Sub-$700 Dual-Motor Scooter With Bold Specs

Today we’re taking an in-depth look at the Kukirin G2 Ultra, an affordable dual-motor electric scooter priced under $700 that promises impressive power and everyday practicality. Boasting two 800W motors and a feature-packed setup on paper, this model stands out in the budget scooter market. But does its real-world performance match its technical specifications? In this full hands-on review, we break down its build quality, design features, riding performance, braking system, battery life, pros, cons, and final value verdict.

Build Quality & Frame Construction

The Kukirin G2 Ultra weighs 30kg and supports a maximum rider weight of 120kg, built with a steel frame structure. The first noticeable detail is its welding work: the steel welds are surprisingly fine for a budget model, but the entire frame relies on stamped sheet metal instead of forged metal—this is the biggest compromise in its build quality.
Stamped sheet metal is widely used in entry-level scooters, and it shows minor flexibility under heavy load. The folding mechanism is the only component constructed with forged metal, which delivers reliable structural stability. In contrast, the vertical column, swingarms, and most load-bearing parts use standard stamped metal with a thickness of 2.5mm, which feels less robust than premium forged alternatives.
The scooter’s folding system is notably cumbersome to operate. The multi-step folding process requires pushing and lowering the column manually, lacking a quick-release design. Its carrying solution is also basic: a simple fabric strap that feels flimsy and low-quality compared to premium carrying systems on mid-range scooters.

Dimensions & Exterior Design Details

The G2 Ultra features a practical body layout with user-centric dimensions: the handlebar sits 123cm above the ground (100cm above the deck), while the deck has a height range of 16cm (lowest) to 23cm (highest). The deck measures 46cm long and 19cm wide, fitted with custom G2 Ultra silicone anti-slip padding to prevent rider slippage during acceleration and braking.
Key exterior details include silicone protective buffers for motor cables and charging ports, effectively preventing cable damage and water/dust ingress. The rear fender uses hard plastic with fixed fasteners for enhanced durability. The handlebar is 64cm wide, slightly arched from a top-down view, with soft, non-slip rubber grips that prioritize hand comfort during long rides (though they lack anti-loosening hardware).

Battery & Charging Performance

Powering the scooter is a 48V 18Ah battery, housed in a thermoformed, explosion-proof casing for improved safety. Unlike basic plastic battery housings on budget scooters, this enclosed design contains potential fire risks, adding a layer of protection for daily use.
The official rated maximum range is 55km, but real-world testing tells a different story. Under aggressive riding conditions—constant dual-motor operation, activated turbo mode, full-speed acceleration from a standstill, and a 100kg rider—the actual achievable range is around 25km on a full charge. Battery drain is noticeable under heavy load: the battery outputs full power when fully charged but experiences slight power attenuation as it depletes, though it never hinders basic climbing and cruising performance.
The included non-ventilated compact charger outputs 2A, requiring a full 9-hour charging cycle for a complete battery top-up. The charging cable setup is practical, with a 90cm cable from charger to battery and an 80cm wall plug cable for flexible placement.

Motor, Suspension & Tire Performance

The core highlight of the Kukirin G2 Ultra is its dual 800W motors (1600W total peak power), equipped on both front and rear wheels. It uses tubeless 10-inch all-terrain tires sized 10*2.75, balancing urban road adaptability and mild off-road capability.
It features adjustable front and rear suspension systems. Riders can tweak the suspension stiffness via a rotary knob: firmer settings suit flat paved roads for stable cruising, while softer settings absorb bumps on gravel, uneven pavement, and small potholes. The suspension performs excellently on small and medium road imperfections, effectively filtering vibration without excessive frame shaking. However, it struggles with large, severe bumps due to the 10-inch tire size.
In real-world tests, the dual motors deliver steady climbing power. Even with a 100kg rider, the scooter maintains a stable 20–25km/h speed on steep slopes without stalling or power lag. Acceleration is linear and non-aggressive, avoiding the sudden jolts found on high-power scooters, making it beginner-friendly.

Braking System: Mechanical + Electromagnetic Dual Brakes

The G2 Ultra adopts a dual braking setup: 160mm front and rear mechanical disc brakes with spring-assisted calipers, paired with an electromagnetic braking system. The spring design ensures the brake lever resets fully after use, preventing stuck brakes.
The electromagnetic brake is a standout feature. It activates with a light squeeze of the brake lever (without engaging the mechanical disc brake) and delivers smooth, effective deceleration. Real-world testing shows the electromagnetic brake can fully stop the scooter from 25km/h in 12–15 meters, with no harsh jolts or noise. For emergency stops, the combination of mechanical and electromagnetic brakes provides reliable stopping power for daily commuting.

Dashboard, Smart Features & Controls

The scooter is fitted with a large full-touch dashboard occupying most of the handlebar, displaying real-time speed, battery level (10-segment indicator), trip distance, cruise control, riding modes, and eco assist levels. It also supports unit switching (km/h and mph) and zero-start/kick-start toggling via long/short button presses.
However, the dashboard has a major flaw: poor visibility under sunlight. Even on cloudy days, most on-screen indicators fade out, making it hard to check real-time speed, turbo status, and riding modes while riding. Operable only in shaded environments, this issue severely impacts usability during outdoor rides.
Additional smart and safety features include front/rear LED lights, directional turn signals, a built-in horn, and Bluetooth speaker connectivity for GPS navigation and music playback. The turn signals are controlled via a joystick, with corresponding dashboard indicators and front/rear LED alerts—though the rear turn signals use red lighting (orange would be more visible for traffic safety).
Riding modes include Eco, Sport, and Race, plus a dedicated Turbo mode for extra acceleration. A key downside is no single motor activation option; the dual motors run simultaneously in all modes, increasing unnecessary battery consumption. The scooter also includes a speed cruise function, which is not recommended for daily use due to potential safety risks.

Speed Limitation & Legal Safety Reminders

The G2 Ultra has a factory top speed of 50km/h, but public road speed limits for electric scooters cap at 25km/h. The scooter is easily derestricted via a simple operation: squeeze the brake lever four times while pressing the power button to unlock full speed.
Critical safety note: Riding over 25km/h on public roads is illegal and voids all insurance coverage in the event of an accident. While the scooter maintains stable handling even at 50km/h with no noticeable handlebar wobble, the stamped metal frame poses structural risks at high speeds. This model is not recommended for teenagers due to its easy derestriction and high potential speed.

Real-World Riding Experience

For adult riders (178cm in height), the handlebar height offers a comfortable riding posture with no back strain, though taller riders (over 190cm) may find the setup cramped. The deck space fits one foot forward and one back for stable standing, though it feels slightly narrow for large shoe sizes (EU 42+).
On flat paved roads, the scooter delivers smooth, stable cruising with linear acceleration. On gravel, uneven dirt roads, and small curbs (20–30cm height), the suspension absorbs impacts well without loose handlebar feedback. Tire grip is reliable on dry surfaces but poor on wet grass or muddy terrain, with noticeable front wheel slipping during turns.
At the factory 25km/h limit, the scooter runs safely and stably with no structural flex. When derestricted, it accelerates steadily to 50km/h with surprising stability, though battery power attenuation becomes obvious at high speeds under heavy load.
