Complete VTB App Setup & Configuration Guide
Meta Description:
Learn how to properly configure your Ventus Aetos controller using the VTB App after installation. This guide covers controller setup, motor calibration, battery and motor selection, Best Tune, speed calibration, safety settings, and required configuration steps for reliable performance.
Ventus Aetos Controller Setup Guide
Installing your Ventus Aetos controller is only the first step. Before riding, the controller must be configured inside the VTB App to match your bike's battery, motor, and hardware.
This guide walks through the required setup process to ensure your controller operates correctly and all features function as intended.
Important: This guide applies to all bikes using a Ventus Aetos controller, not just the Ultra Bee shown in the video.
Before You Begin
Before configuring your controller:
- Install the Aetos controller completely.
- Place the bike securely on a stand.
- Turn the bike ON.
- Download the VTB App from the Apple App Store or Google Play Store.
- Enable Bluetooth on your phone.
Step 1: Connect to the Bike
- Open the VTB App.
- Allow the app to connect to the controller.
- Once connected, open:
Parameter Settings
This is where nearly all required setup will be completed.
Step 2: Complete Controller Setup Guidance
Select:
Controller Setup Guidance
Here you'll configure three important items:
- Bike Model
- Battery
- Motor
Each selection must match the hardware installed on your bike.
Select Your Bike
Choose the correct bike model from the list.
Examples include:
- Ultra Bee
- Light Bee
- Ventus
- Other supported platforms
Always choose the correct platform for your controller installation.
Select Your Battery
Next, choose the battery installed in your bike.
Examples may include:
- Stock battery
- Pegasus battery
- Other supported aftermarket batteries
Using the correct battery profile allows the controller to safely calculate:
- Voltage
- Current limits
- Power delivery
- Battery protection
After selecting the correct battery, press Save.
Select Your Motor
Choose the motor currently installed.
Example:
- Ryuga 81kW Motor
- Other supported Ventus motors
Selecting the correct motor profile ensures the controller uses the proper motor characteristics.
Verify Sensor Configuration
Before saving, verify that all sensor settings match your motor.
Check:
- Temperature Sensor
- Hall Sensor
- Encoder Settings
Incorrect sensor configuration can result in:
- Fault codes
- Motor errors
- Calibration failures
- Poor motor performance
Always double-check these settings before continuing.
Step 3: Perform Motor Calibration
After setup guidance has been completed, navigate to:
Calibration Settings
Motor calibration teaches the controller the correct motor rotation and electrical timing.
Important Safety Notice
Before beginning calibration:
- Bike MUST be on a stand
- Rear wheel must spin freely
- Keep hands away from the wheel
- Hold the bike securely during calibration
Never perform motor calibration with the bike on the ground.
Clockwise vs Counterclockwise
The calibration menu allows you to choose:
- Clockwise
- Counterclockwise
Which option is correct depends entirely on how the motor phase wires were connected during installation.
If the Wheel Spins Backwards
If the rear wheel rotates in reverse:
Simply repeat the calibration using the opposite direction.
There is no need to disconnect or rearrange the motor wires.
Changing the calibration direction corrects the motor rotation electronically.
Successful Calibration
During calibration:
- The rear wheel will begin spinning.
- The controller learns the motor position.
- Once complete, the app will indicate calibration was successful.
Press:
Save
to continue.
Complete the Remaining Calibrations
Continue through the remaining calibration screens by following the instructions shown inside the VTB App.
Each calibration only takes a few moments and ensures proper controller operation.
Step 4: Configure Best Tune
After calibration, open:
Best Tune
This section allows the bike's power delivery to be tailored to your riding style.
Examples include:
- Higher top speed
- Stronger acceleration
- Road racing
- Trail riding
- Technical riding
- Torque-focused setups
The controller can be optimized based on how you ride.
Auto Match Library
The VTB App also includes an:
Auto Match Library
This contains pre-configured tunes developed for common hardware combinations.
Depending on your setup, you can select a tune from the official library instead of building one manually.
This provides an excellent starting point for most riders.
Step 5: Configure Speed Calculation
To ensure the speedometer displays an accurate speed, configure:
Speed Calculation
Enter:
- Rear sprocket tooth count
- Rear tire size
These values allow the controller to calculate wheel speed accurately.
Incorrect values may cause the speedometer to display inaccurate speeds.
Step 6: Wheelie Mode
If your controller supports Wheelie Mode, you can configure it here.
Settings include:
- Wheelie angle
- Activation level
Adjust these values to match your riding style and comfort level.
Step 7: Safety Sensor Settings
Near the bottom of the settings page you'll find several optional safety sensors.
These include:
- Brake Sensor
- Kickstand Sensor
- Tilt Sensor
These can be enabled or disabled depending on your application.
Race Bikes
Many competition bikes disable these sensors to eliminate unnecessary interruptions during racing.
Trail or Recreational Riding
Most recreational riders should leave these safety features enabled unless they understand the implications of disabling them.
Common Setup Problems
Rear Wheel Spins Backwards
Cause:
Motor direction selected incorrectly.
Solution:
Repeat motor calibration using the opposite rotation direction.
Motor Errors After Installation
Possible causes include:
- Incorrect battery selection
- Incorrect motor selection
- Hall sensor configuration
- Temperature sensor settings
- Encoder settings
Verify every item in the Controller Setup Guidance menu before recalibrating.
Incorrect Speed Display
Verify:
- Rear tire size
- Rear sprocket tooth count
Incorrect values will affect speedometer accuracy.
Recommended Setup Order
For the best results, complete setup in this order:
- Install the controller.
- Turn the bike ON.
- Connect to the VTB App.
- Complete Controller Setup Guidance.
- Select the correct bike model.
- Select the correct battery.
- Select the correct motor.
- Verify sensor settings.
- Perform motor calibration.
- Complete remaining calibrations.
- Configure Best Tune.
- Set Speed Calculation.
- Configure Wheelie Mode (optional).
- Review safety sensor settings.
Summary
Proper setup inside the VTB App is required after installing any Ventus Aetos controller. Begin by selecting the correct bike model, battery, and motor, then verify all sensor settings before saving. Perform the motor calibration with the bike securely on a stand, reversing the calibration direction if the rear wheel spins backward. Once calibration is complete, configure the Best Tune for your riding style, enter your sprocket and tire size for accurate speed readings, and customize optional features such as Wheelie Mode and safety sensors. Completing these steps ensures the controller delivers smooth, reliable performance while unlocking the full capabilities of the Aetos platform.
