Intuitive and configurable interface

Thanks to the integrated Avinox drive system, the Reason allows users to easily record all ride data. With advanced sensors that collect nearly 50 metrics, the control screen can be customized via the Avinox app, including details such as ride duration, range, average speed, and real-time power output.

DJI has developed dual wireless controllers that connect to the main screen via Bluetooth. This eliminates the need for cables, simplifies maintenance, and enables fast switching between assist modes with quick access to various functions and commands.

Smartphone integration for enhanced security

The Avinox mobile app unlocks the full potential of the system. Once paired via Bluetooth, it allows users to protect the bike, manage ride data, customize assist levels, and monitor the e-bike’s status in real time. It also sends alerts in case of unusual movement and provides other smart features.

Tailored parameters

After syncing with the Avinox app, riders can customize the display parameters to their preferences and riding styles. Settings can also be adjusted directly from the phone depending on the needs of each ride.

Smart bike protection

When the bike is connected to the smartphone via Bluetooth, it can be unlocked automatically as the user approaches. The system also includes safety features that send alerts to the phone if suspicious movement is detected, helping users stay informed about the bike’s location and status.

Smart diagnostic system

If an issue is detected in the drive system, a visual and audible alert will appear on the screen. The app allows users to identify, locate, and quickly resolve any errors to keep the bike functioning properly.
