92.6% Motor Conversion Rate
Through extensive research and analysis, we proudly present our cutting-edge brushless magnet motor. Each component of the U-Series’ electric powertrain has been precisely designed to achieve the perfect balance between power and energy efficiency, ensuring that the motor provides sufficient power while reducing power loss.
Field Oriented Control (FOC)
NIU developed its FOC vector controller to communicate with the U-Series’ motor. After configuring a sophisticated algorithum, rigorous motor tests, and adjusting the power input, we achieved a smooth acceleration rate of 10% input ≈ 10% output. The FOC is the latest in original, state-of-the-art technology.
Electronic Braking System (EBS) & Regenerative Braking System
When you hit the brakes on a normal scooter, kinetic energy produced and then wasted. With our NIU UQi-Series (former NIU U-Series) EBS, the kinetic energy produced during braking is captured and recycled back into the battery, extending your range by up to 6%.
NIU U-Series Cloud ECU
As the intelligent core of the NIU UQi-Series (former NIU U-Series), the Cloud ECU acts like a private scooter analyst, helping you complete the collection, diagnosis, and processing of your driving data. Using the cloud connection after each ride, the data analysis optimizes the intelligent riding experience by learning about your driving habits.
New Six-Axis Motion Sensor
The U-Series’ anti-theft alarm accuracy range has been shortened to only 3 meters thanks to the new MEMS six-axis motion sensor. Using the on-board gyroscope to measure the vehicle’s acceleration and GPS positioning, we are able to more accurately identify an unauthorized movement of your scooter.
The MEMS six-axis is not just an anti-theft tool. It detects all kinds of movements in your scooter. You can even get a notification on your phone if your scooter topples over.
3 Meters Anti-Theft Precision Range
Battery Management System (BMS)
We have designed and developed our next generation BMS. The BMS does more than provide a precise calculation of charge and discharge. It analyzes the current, voltage, temperature, communications, and 10 other electrical protection mechanisms to ensure that each section of the battery is protected and operating efficiently.
10 Point Battery Protection
The UQi-Series (former U-Series) is our first scooter to use keyless ignition. The U-Series key allows you to remotely unlock your scooter from up to 50 meters away. When you’re ready to ride, simply press the “Niu logo” button on the key to turn your scooter and be on your way.
All New “Naked” Frame
When you first meet the NIU UQi-Series scooter (former NIU U-Series), your eyes are drawn to its external 38mm steel frame. Not only does it look great, but the Q235 steel has excellent torsonial rigidity and low longitudinal stiffness, providing the right balance between carrying capacity and maneuverability.
Daytime Running Lights
At NIU, safety is our top priority. The U-Series is equipped with daytime running lights and a 360 degree LED lighting system. Pedestrians and drivers have no problem spotting you when on the road, reducing the likelihood of accidents. The U-Series has an all-new external “Halo” headlamp that is first and foremost designed for safety while also being a bit quirky; letting the U scooter standout for both its form and function.
NIU Motor Lock
We have added one new layer of theft protection, the Niu Motor Lock. The motor lock can be activated if an unauthorized movement of your scooter is made. You can be rest assured that the lock can only be activated when the scooter is in a “parking” mode.
NIU U-Series – It started from a sketch
Original design is, and will always be, the fundamental principle of NIU. Our goal was to create a design with the future in mind that still meets today’s everyday needs. From here, the U-Series was born. It is the perfect balance between convenience and style.
NIU was founded on the principles of great design. As a design orientated company, we strive to improve the everyday lives of citizens by giving riders the power to do more with vehicles they are proud of.
After a lot of research into color psychology, our choice of colors align perfectly with current trends. No matter what kind of rider you are, we have a color for you.
A Modular Influenced Design
When we started on the NIU U-Series project, we realized that every urban rider has their own needs.
So from the first sketches, we set out to find a way to blend form with function. If you look closely at the final design you will find elements of some of these original sketches.
A Work of Art
When building the U-Series, the first question that came to mind was: what is a practical electric scooter? How can we allow more people to explore and engage with the NIU electric lifestyle? After a tremendous amount of design, performance, and research, we are proud to bring the U-Series to the global stage.
More Than A Scooter
The NIU UQi-Series (former NIU U-Series) is not a simple 2-wheeled vehicle. It is the reimagination of urban mobility, and your faithful travel partner.
