Self-Learning Motor Calibration (Required)

The SpeedMaster V4 controller includes a motor auto-learning process to ensure compatibility with your scooter’s motor specs.
To initiate self-learning:
1. Make sure the scooter is powered off and placed on a flat, stable surface.
2. Hold the power button for about 10 seconds.
3. The wheel will spin slowly forward, then backward.
4. A “beep” sound indicates successful calibration.

Easy Installation

No soldering required, and no special tools necessary. With basic mechanical skills and patience, most users can complete the upgrade themselves. A step-by-step installation video and written instructions are included.
