## What Is It? ### What Is It?
The VESC2X3Bridge is a project I started at the end of 2025. It aims to integrate the X3 Scooter Series from Ninebot into the world of VESC, an open-source project by Benjamin Vedder.

The VESC2G3Bridge is a small computer that sits between your scooter's motor controller (VESC) and its dashboard (G3). Without it, the dashboard and the motor controller don't understand each other — the bridge acts like a translator so they can work together.

### Shows Your Speed #### Shows Your Speed
The device reads how fast the motor is spinning and works out your actual riding speed. It then sends that number to the dashboard so you can see it while you ride.

### Switches Ride Profiles #### Switches Ride Profiles
The scooter can have different power modes (WALK,ECO,NORMAL,SPORT). The bridge listens to the dashboard buttons and tells the VESC which mode to switch to. You can also set it to block the switching of modes when the battery is low, bypassing the dashboards auto apply of a slow profile. The scooter can have different power modes (WALK,ECO,NORMAL,SPORT).

By running a small script on the VESC, the VESC can directly read the inputs from the dashboard, giving the VESC full control over how you accelerate and slow down.

### Tracks Multiple Motor Controllers #### Tracks Multiple Motor Controllers
If your scooter has more than one VESC (e.g. dual motors), the bridge reads speed data from all of them and averages the values together for a smooth, accurate speed reading.
