Ventus Throttle Recalibration — Fix Deadband & Throttle Response Issues

1. Overview

This article explains how to fix throttle deadband or poor throttle response on your Ventus bike by performing a throttle recalibration.

If your throttle has a delay before power engages, inconsistent response, or does not deliver smooth power, recalibrating the throttle typically resolves the issue.

Follow the video guide linked below to properly recalibrate your throttle and restore normal throttle response.

2. When Should You Recalibrate?

Throttle recalibration is recommended if you experience:

• Throttle deadband before power engages
• Delayed throttle response
• Inconsistent throttle input
• Weak throttle response at low input
• Throttle response issues after controller setup or service

Recalibration resets throttle input values so the controller correctly reads throttle position.

3. Prerequisites

Before starting, make sure:

• Bike battery is charged
• Bike is powered on
• Bike is in a safe, stable position
• Throttle moves smoothly without obstruction

Note: The wheel will not spin during throttle calibration.

4. Step-by-Step Instructions

Video Guide — Throttle Recalibration

Follow this step-by-step video to recalibrate your throttle:

The video demonstrates the correct process to reset throttle calibration and eliminate deadband or throttle response issues.

Expected Result

After recalibration:

• Throttle responds immediately
• Deadband is removed or reduced
• Power delivery becomes smoother and predictable
• Low-speed throttle control improves

Tips

• Fully release throttle before starting calibration.
• Rotate throttle smoothly when prompted.
• Do not interrupt the calibration process.
• Repeat calibration if response still feels incorrect.

5. Pro Tips & Suggestions

✅ Recalibrate After Controller Changes
If controller settings are updated or replaced, recalibration may be required.

✅ Recalibrate After Throttle Replacement
Any throttle hardware change requires recalibration.

✅ Recalibrate If Response Changes
If throttle response begins to feel inconsistent over time, recalibration is a quick fix.
