NIU NQIX 70+KMH Bluetooth Controller (Bluetooth Programmability & Speed Unlock)

Description

Unlock the full potential of your ride with our NIU NQIX speed unlock upgrade, designed to make your NIU NQIX scooter faster and more powerful than ever.

This controller is designed specifically for NIU NQIX scooters and works fully with the original connectors.
Installation is plug & play — no modifications required.
All original scooter functions such as lighting, dashboard, throttle response, TCS, and reverse mode are fully retained.

The controller comes with built-in Bluetooth and supports app connectivity, allowing you to modify a wide range of parameters including:

• Speed per mode (ECO / DYNAMIC / SPORT)
• Acceleration strength
• Regenerative braking levels
• Other advanced settings for battery and motor optimization

Through the app, users can also view detailed motor and battery information, enable an alarm feature, and adjust controller settings directly via smartphone.
A complete Bluetooth programming guide will be provided after purchase, explaining how to register and use the app effectively.

Performance Options

The standard controller includes:

• Line Current: 200A
• Phase Current: 450A

This configuration provides an excellent balance of power and efficiency for the original NIU motor and battery setup.

If you are going to upgrade the motor or battery you can consider the controllers below:

For users upgrading their scooter with higher-capacity batteries or dual-battery setups, we also offer:

• Upgraded Version: 400A Line / 800A Phase
• Extreme Version: 600A Line / 1800A Phase

These options are designed for modified scooters that demand higher output.
If your scooter still uses the original NIU battery and motor, the standard version will already deliver significant improvements.

Why This Upgrade Matters

Unlike software-based unlocks, this controller upgrade is a hardware enhancement.
It allows your scooter to handle a larger ampere current, resulting in higher top speed and stronger acceleration.
If you plan to upgrade to a more powerful battery or add a second pack, you can easily adjust the controller settings through the app to match your configuration.
