4. Operating Instructions
Familiarize yourself with the controls and functions of your electric bike before riding.
4.1 Powering On/Off
Insert the key into the ignition. Turn the key to the 'ON' position to activate the electric system. Turn the key to the 'OFF' position to power down the bike. The bike can also be ridden as a traditional bicycle when powered off.
4.2 Riding Modes
The WINDHORSE W3 offers two primary riding modes:
- Pedal-Assist System (PAS) Mode: When the bike is powered on and you begin pedaling, the motor will provide assistance, making pedaling easier. The level of assistance may be adjustable via the display.
- Electric-Only Mode (Throttle): Engage the throttle to propel the bike without pedaling. This mode provides full motor power up to the set speed limit.
You can also pedal and use the throttle simultaneously for an additional boost.
4.3 Lighting System
To activate the headlight, turn the key twice to the far right. The bike is also equipped with a rear reflector for enhanced visibility. Ensure lights are functional for nighttime riding.

- Tire Pressure: Check tire pressure before each ride. Maintain recommended pressure for optimal performance and safety.
- Brake Inspection: Regularly inspect brake pads and discs for wear. Ensure brake levers operate smoothly and provide adequate stopping power. Adjust or replace components as needed.
- General Cleaning: Keep the bike clean. Use a damp cloth to wipe down the frame and components. Avoid using high-pressure washers directly on electrical parts.
