Kukirin G2 Ultra Electric Scooter Full Review: Dual-Motor Power & Real-World Performance Test

Jun 24, 2026 by KUGOO Electric Scooter

Today we’re taking a comprehensive hands-on look at the Kukirin G2 Ultra electric scooter, the upgraded flagship variant sitting above the standard Kukirin G2 model. This model joins Kukirin’s refreshed scooter lineup, which also includes the G3 and G4. As one of the long-standing, reputable original brands in the electric scooter industry, Kukirin has built its reputation by balancing solid build quality with budget-friendly pricing, and the G2 Ultra aims to carry that philosophy while packing major performance upgrades over its base sibling.
Throughout this review, I will walk through its complete specifications, key upgrades versus the regular G2, real-world top speed testing, emergency braking performance, on-road and off-road handling, hill-climbing ability, actual battery range results, standout premium features, and one frustrating design flaw that impacts daily transport convenience.

Pricing & Warranty Overview

The official retail price for the Kukirin G2 Ultra is $1,699 on the brand’s official website, though a limited-time promotional price brings the cost down to just $949. Securing a dual-motor high-performance electric scooter under $1,000 makes this unit extremely competitive within its price bracket.
For buyers who prefer to split payments instead of paying the full amount upfront, installment payment options are available to spread the total cost into four separate payments for easier budgeting.
In terms of after-sales protection, the scooter comes with a standard 12-month manufacturer warranty. Should factory defects or component failures arise within the first year of ownership, customers can contact Kukirin’s support team for troubleshooting guidance. The brand also supplies replacement spare parts when needed and provides step-by-step guidance for self-repair work.

Core Power & Speed Performance

The biggest upgrade defining the “Ultra” badge is its dual 800-watt motor setup. The standard Kukirin G2 only features a single rear motor, while the G2 Ultra doubles total power output, delivering drastically snappier acceleration, stronger climbing torque, and a higher theoretical top speed rated at 31 miles per hour by the manufacturer.
Right out of the factory, the scooter is pre-programmed with a speed limiter to comply with regional traffic regulations worldwide. For regions where higher-speed riding is legally permitted, there is a simple procedure to remove the speed restriction:
  1. Power on the scooter; a small indicator dot under the battery icon confirms the speed limiter is active
  2. Hold the left brake lever continuously, then quickly tap the power button four times in sequence
  3. Release the brake lever; the indicator dot will disappear to signal the limiter is disabled
Important note: This demonstration is for informational purposes only, and riders must always abide by local electric vehicle speed laws and regulations.
During real-world GPS top-speed testing with the scooter set to Race mode and Turbo function activated, the G2 Ultra comfortably exceeded its official rating, hitting a peak speed of 36 mph, with impressively aggressive linear acceleration throughout the speed run.

Battery Configuration & Actual Range Test

Powering the dual motor system is a 48V 18Ah lithium-ion battery pack housed inside the deck of the scooter. In factory Eco mode, Kukirin states a maximum rated range of up to 34 miles per full charge.
To reflect realistic high-performance usage, all real-world testing was completed using Race mode with Turbo fully enabled. After a full ride session combining street cruising, off-road exploration, hill climbs and acceleration runs, the scooter finished with one battery bar remaining after traveling 21.2 miles, nearly matching the brand’s estimated 22-mile range for this aggressive riding profile.
A notable safety design choice is the explosion-proof casing surrounding the internal battery pack. This structural feature reduces fire and explosion risks, easing concerns for indoor or garage storage of the scooter.

Braking, Tires & Suspension System

Braking System

The G2 Ultra is equipped with front and rear mechanical disc brakes, a typical configuration for scooters in this price tier. Over more than 50 miles of pre-test riding, the brake set operated smoothly with no squealing, grinding or uneven friction issues. During an emergency brake test starting at 27 mph, combined mechanical disc braking and electronic regenerative braking brought the scooter to a complete stop in roughly 40 feet, delivering reliable, responsive stopping power for sudden road hazards.

Tires

This model rolls on 10-inch tubeless tires with moderate tread depth, suitable for both paved pavement and light off-road terrain including grass, dirt and loose gravel. The main downside is the relatively narrow tire width; while maneuverable, these tires tend to sink and dig into soft sand during off-road cornering, requiring extra rider caution on sandy surfaces. Even so, the scooter maintained stable control during grass riding, reaching a sustained speed of 28 mph on thick Saint Augustine grass with no traction failures under full throttle.

Suspension Setup

Front and rear swingarm spring suspension comes standard, adjustable for softer or firmer compression using a spanner wrench. I tested the scooter using factory default suspension settings, which struck an ideal middle ground—not overly soft to cause bottoming out over bumps, nor stiff enough to transmit harsh road vibration directly to the rider. The suspension operates nearly silently with no rattling or creaking over uneven pavement, wooden boardwalks, rocks and uneven dirt trails, smoothing out most small and mid-sized road imperfections effectively.

Frame, Folding Mechanism & IP Rating

Compared to the solid stem on the base G2, the G2 Ultra features a refined hollow handlebar stem first introduced on the Kukirin G4. Rounded edge styling improves aerodynamics and gives the front assembly a sleeker overall aesthetic.
Folding the scooter is designed for simplicity: squeeze the release lever to disengage the stem lock, pull out the safety pin, then pivot the stem downward for storage. Assembly after transport is equally straightforward by locking the stem back into its upright position.
The scooter carries an IP54 ingress protection rating, meaning it can withstand light rain splashes with no internal water damage. This is practical for humid, storm-prone climates such as South Florida, where short afternoon thunderstorms are common. However, it is not designed for deep puddle crossing or full submersion in water, so riders should avoid heavy downpour exposure whenever possible.

Handlebar Cockpit & Interface Upgrades

One welcome quality-of-life upgrade over the original G2 is the redesigned control dashboard. Older Kukirin models featured a small, unresponsive touchscreen that required repeated taps to register inputs. The G2 Ultra replaces this with a large, wide touch display spanning most of the handlebar width, with instant, reliable touch responsiveness for every command.
The primary drawback of this new screen is its straight-upward orientation, which creates severe glare and poor visibility under direct bright sunlight.
Breaking down the handlebar controls:
  • Left side: Textured non-slip hand grips, front brake lever, horn switch, headlight trigger, left and right turn signal buttons
  • Right side: Matching textured grip, rear brake lever, thumb throttle and main power button
  • Separate physical key switch for full scooter power activation
The touchscreen displays real-time battery percentage, current speed, total odometer mileage, and multiple configurable functions:
  • Mode button: Cycles between Eco, Sport, and Race power profiles
  • Cruise control toggle: Activates or deactivates constant-speed cruising
  • Set button: Switches speed readout between miles per hour and kilometers per hour
  • Turbo button: Enables full maximum motor output; with Turbo off, motors are restricted to just over half their total power output

Standout Premium Feature: Built-In Bluetooth Speaker

My personal favorite exclusive feature on the G2 Ultra is an integrated Bluetooth speaker mounted directly within the upper handlebar assembly. Many competing scooters place speakers low on the frame, resulting in muffled, hard-to-hear audio while riding at speed. This elevated speaker placement delivers clear, audible music playback during cruising, adding major recreational value for casual leisure riding.

Off-Road & Hill Climbing Performance

I put the dual-motor powertrain through rigorous off-road testing across dirt mounds, loose sand, rocky trails and small inclines. Despite narrow tires digging slightly into loose sand during sharp turns, the dual 800W motors supplied ample torque to conquer steep small hills without stalling or bogging down. Descending slopes remained controlled thanks to the combined mechanical and electronic braking system. While not built for extreme heavy off-roading, it handles light trail, grass and gravel riding with impressive capability for a street-focused electric scooter.

The Biggest Design Flaw: Folding Securing Strap

After extensive use, one persistent design choice across Kukirin’s newly redesigned G2, G3, G4 and G2 Ultra lineup stands out as a major annoyance: the folding retention system.
Most comparable scooters use a built-in hook-and-loop lock to secure the folded stem firmly in place for vehicle transport. Instead, this model relies on a standalone fabric strap that wraps around the kickplate to hold the folded stem. This setup creates excessive slop and wobble; once loaded into a vehicle, the handlebar assembly shifts and flops around during driving. In some instances, the strap slips loose entirely, leaving the stem twisting freely inside cargo space.
This simple strap solution feels cheap and impractical for transport, and it would be a significant improvement if Kukirin reverted to a built-in positive locking mechanism for folded storage. It is usable with extra care, but it is easily the scooter’s most frustrating design compromise.

Final Verdict

After full testing covering top speed, braking, battery range, street agility, off-road capability and daily usability, the Kukirin G2 Ultra delivers exceptional value at its $949 promotional price point. The dual-motor configuration easily outperforms the base G2 in acceleration, speed and hill-climbing power, paired with upgraded touchscreen controls, a convenient built-in Bluetooth speaker, balanced suspension and reliable stopping performance. Real-world range closely matches official estimates for high-performance riding, and its build quality aligns with Kukirin’s long-standing reputation for affordable, durable electric scooters.
The only meaningful downside is the poorly engineered folding strap lock for transport, a nuisance that buyers will need to accommodate if regularly loading the scooter into vehicles. If you are shopping for a powerful dual-motor commuter and recreational electric scooter on a mid-range budget, the Kukirin G2 Ultra is an extremely competitive option worth serious consideration during its promotional pricing window.
