Design and Build Quality

The Niu KQI Air stands out as an exceptional scooter, particularly due to its design and build quality. Uncommon in the scooter world, it boasts an extraordinary combination of lightweight construction and high durability, making it a rare gem in the market.

One of the standout features of the Niu KQI Air is its extensive use of carbon fiber throughout its construction. Depending on the version chosen, you can find carbon fiber in various parts of the scooter, such as the stem, frame, rear standing guard, and upper section. This not only enhances the scooter’s aesthetic appeal but also contributes significantly to its weight reduction. In the R version, the scooter weighs a mere 11.7, and in the RX version, it is only 11.9. Such weight figures are truly remarkable in the realm of scooters.

The assembly of the Niu KQI Air is described as impeccable, emphasizing the attention to detail in its construction. The scooter comes loaded with features and options, making it a comprehensive and versatile choice for riders. Its deck, with a width of 19 cm, ensures comfortable foot positioning, while a small crutch on the side adds to the convenience.

The braking system is seamlessly integrated, with a disc brake on the front wheel activated through a control on the handlebars. The lighting system is not only functional but also innovative. The rear light, constantly lit, pulses when the braking system is engaged, providing an extra safety feature.

Security is a top priority for the Niu, featuring anti-theft measures. The scooter can be unlocked via Bluetooth using your smartphone or NFC using provided cards. These cards are programmable through an application, offering a customizable and secure means of access.

The scooter’s onboard screen displays crucial information, while the carbon fiber handlebar contributes to the overall lightweight design. The scooter’s speed and autonomy can be modulated through the application, giving riders control over their riding experience.

Additional practical features include an ignition button, horn, and turn signals integrated into the handlebars. The turn signals emit a strong light, ensuring visibility to others on the road. The headlight at the front illuminates approximately ten meters ahead, providing both safety and style.

So, the KQI Air is a marvel in the scooter world, marrying cutting-edge design with top-notch build quality. Its lightweight construction, carbon fiber components, and advanced features make it a standout choice for riders who value both performance and aesthetics in their electric scooters.

Niu KQI Air: Motor and Driving Test

Moving on to the rear part of the Niu KQI Air, the focus is on its propulsion system, powered by a 350W motor capable of reaching peaks of up to 700W. This rear-wheel drive setup is complemented by a comprehensive braking system, ensuring both acceleration and deceleration are well-managed.

As we delve into the test ride, the emphasis begins with the comfort level, starting with the driving position. Standing at 1.76 meters, I find the driving position to be excellent. The 19 cm wide deck, although not expansive, accommodates parallel foot positioning comfortably. Despite the relatively modest width, I opted for this configuration rather than the recommended staggered foot positioning, finding it to be a personal preference that works seamlessly.

The grip on the deck, comprising small 3 cm strips on the lateral parts, pleasantly surprises me. Despite expectations of a smoother surface, the grip proves effective, securely anchoring the feet to the scooter. The acceleration aspect is briefly mentioned, with the promise of a more detailed exploration in the forthcoming section dedicated to speed.

Transitioning to the discussion of suspension, it’s noted that the Niu KQI Air lacks this feature both in the front and rear parts. The absence of suspension makes it clear that this scooter is not designed for jumps or rough terrain. However, riding on asphalt is smooth, and the 9.6-inch tires offer some capacity to absorb road irregularities, enhancing safety, especially when encountering certain obstacles like speed bumps.

I acknowledge the scooter’s lightweight construction as a significant advantage, particularly for transport. The ease of removing and carrying the scooter is highlighted, emphasizing its minimal weight. The absence of suspension is recognized as a trade-off, impacting the comfort on uneven surfaces. However, the lightness of the scooter remains a considerable advantage, especially for transport purposes.

When the Niu KQI Air is in the off state, attempting to move or pick it up reveals an interesting security feature. The handlebars rise automatically, activating a braking mode that is imperceptible to the user but acts as a theft prevention measure. This feature ensures that the scooter remains stationary and deters any unauthorized movement.

Continuing the exploration of its security features, the upper part of the scooter reacts strongly to unauthorized attempts to move it. Activating warnings and emitting an unpleasant beep, the scooter makes it clear that any unauthorized handling is unwelcome. This adds an extra layer of security, making the Niu KQI Air less appealing to potential thieves.

One noteworthy feature highlighted during the test ride is the presence of cruise control. Activated by staying on the handle for 5 seconds at a constant speed, cruise control enhances the riding experience. The audible beep indicates the engagement of cruise control, providing a convenient option for riders.

The desire for full suspension is expressed, acknowledging that it would have been a valuable addition, given the scooter’s premium character. However, the absence of full suspension is partially compensated by the exceptional lightness of the scooter, making it stand out in its category.

It then delves into the performance of the 350W motor located in the rear, emphasizing its propulsion system. Despite a personal preference for traction, I acknowledge the efficiency of the propulsion setup. The scooter is capable of reaching and maintaining speeds close to the regulatory limit of 25 km/h, adhering precisely to regulations. The acceleration modes, customizable through the application, provide a sporty and enjoyable driving experience.

The scooter’s climbing ability is demonstrated on a hill, showcasing the power and resourcefulness of the motor. Even at the very end of the battery life, the scooter performs admirably on inclines, demonstrating its capabilities.

The braking system is praised for its effectiveness. A combination of a magnetic brake integrated into the motor on the rear wheel and a disc brake on the front wheel ensures a smooth and prompt deceleration. I noted a quick transition from 25 km/h to 0 in just 4 meters, aligning with the performance of other scooters in the market. The option to adjust energy recovery at the rear through the application adds a customizable element to the braking experience.

Battery and Range

The Niu KQI Air features a battery energy recovery system that is integrated into the deck, housed within the battery plate proudly bearing the LG signature. This innovative design not only ensures the scooter’s aesthetic appeal but also contributes to its efficiency and performance.

The battery, operating at a robust 48 V, is a noteworthy element that enhances the overall capabilities of the scooter. The use of a 48 V battery is expected to be explored further in the section dedicated to the scooter’s power.

Remarkably, despite the weight typically associated with electric scooters due to their batteries, the Niu KQI Air manages to maintain a remarkably low overall weight. This is particularly impressive given the structural rigidity of the scooter, including the rigidity of the deck and the seat. The scooter’s design prioritizes lightweight construction without compromising on strength, providing a combination of durability and maneuverability.

Regarding the range, the scooter boasts an impressive capacity, with the battery offering an estimated travel distance of around 50 km. The actual range may vary depending on factors such as rider weight, road conditions, and speed. I emphasize the scooter’s ability to maintain this impressive range, even during dynamic use, such as small jumps. While not the primary purpose of the scooter, it underscores the durability and reliability of the battery in varied riding conditions.

The application provides real-time information on the battery’s usage and the distance traveled, allowing riders to monitor their remaining range accurately. I note being on track with the estimated 50 km range, reinforcing the scooter’s reliability and consistency in delivering on its promised performance.


Welcome to the application developed by Niu to control your electric scooter, a hub of insightful information and convenient features. This Bluetooth-enabled application offers a range of functionalities, making it an essential companion for Niu KQI Air riders.

Niu KQI Air Review: application

One of the key features is the ability to activate the scooter remotely through the application, providing a seamless and modern way to start your ride. The Bluetooth connectivity ensures a secure and reliable connection between your smartphone and the scooter.

One of the most crucial pieces of information provided by the application is the range, giving you real-time data on the remaining battery percentage. This feature is invaluable for planning your rides, ensuring you have sufficient charge for your intended distance.

The application also offers a comprehensive overview of your riding history, displaying details about different routes you’ve taken. This includes the total distance traveled during each session, the time of the ride, the percentage of battery consumed, and the average speed achieved. This data not only serves as a helpful log for your personal records but also aids in optimizing your riding habits for efficiency.

Niu KQI Air: Conclusions

In the end, having the Niu KQI Air electric scooter at your disposal is truly exceptional. With a weight of around 10 kg, it defies the norm of heavier electric scooters, making it remarkably easy to carry and maneuver. The low plate and wide handlebar provide a sense of security and precise maneuverability, contributing to an enjoyable riding experience.

While the scooter performs well on the road and features a powerful motor capable of tackling tough hills, the absence of full suspension is noted. Despite this, the scooter compensates with its outstanding lightness, making it a standout choice in its price range. The efficient braking system, capable of stopping in just 4 meters from 25 km/h, aligns with the expectations of riders seeking responsive and reliable braking.

I express a preference for certain brake settings and suggest the addition of a drum brake on the rear wheel. Despite being lent by the brand, the scooter is regarded as a valuable option, especially for those considering the R version for its perceived better value for money.

In terms of design choices between the R and X versions, I lean towards the R version, emphasizing that the differences in weight between the two are not substantial. The price is readily available in the video description, providing transparency for potential buyers.
