2. Mounting the Tail Light
The NT101 offers two installation options: seatpost mount and cargo rack mount.
Seatpost Mount:
Attach the seatpost mount to your bike's seatpost using the provided hardware. Ensure it is securely fastened. The mount fits round seatposts (28-35mm in diameter, circumference 85-110mm) and some aero seatposts with a width of <= 3.5cm. Insert the tail light unit into the mount until it clicks into place.
Cargo Rack Mount:
If your bike has a cargo rack with an interface shown in the product images (distance between holes 4cm-8.5cm), use the cargo rack mount. Secure the mount to the rack using the provided screws. Slide the tail light unit onto the mount until it locks.

3. Mounting the Remote Control
The wireless remote control can be mounted on your handlebar for easy access. Use the provided rubber rings to secure the remote to a convenient position on your handlebar.

Operating Instructions
1. Power On/Off
Press and hold the power button on the tail light unit or the remote control to turn the device on or off. The light will illuminate when powered on.
2. Light Modes

- Steady On (High, Mid, Low brightness)

- Warning Flash
- Pulsating Light
- Hazard Lights

3. Turn Signals
Press the Left or Right turn signal button on the remote control to activate the corresponding indicator. The turn signal will flash for 10 seconds and emit an audible click sound, clearly indicating your turning direction. You can cancel the signal by pressing the button again. The audible click sound can be muted by pressing and holding the turn signal button for 3 seconds.
Figure 7: The NT101 features distinct left and right turn signals for clear indication.
4. Ground Warning Lines (Laser)
Press the "LASER" button on the remote control to activate the ground warning lights. These lights project two red lines on the ground on either side of your bike, creating a visible safety zone for incoming vehicles, especially useful at night.
Figure 8: The ground warning lines help define a safe distance for other road users.
5. Brake Detection
The NT101 features an intelligent brake detection system. When the device senses a reduction in speed (braking), the tail light will automatically brighten for 2 seconds to alert traffic behind you, similar to a car's brake light. This feature significantly enhances safety.
6. Anti-Theft Alarm
To activate the anti-theft alarm, press the "A/S" button on the remote control. Once activated, the tail light becomes vibration-sensitive. If it detects any movement or vibration when you are away from your bike, it will emit a loud 110dB alarm to deter potential theft. The sensitivity of the alarm can be adjusted across 10 levels to prevent false alarms. Refer to the detailed instructions in the full user manual for sensitivity adjustment procedures.
Figure 9: The 110dB anti-theft alarm provides an audible deterrent against tampering.
7. Electric Bike Horn
The NT101 is equipped with a 110dB electric horn. Press the "Horn" button (speaker icon) on the remote control to sound the horn, alerting other road users to your presence.

Maintenance
1. Charging
To ensure optimal performance and battery longevity, charge the NT101 regularly, especially when the battery indicator shows low power. Avoid completely draining the battery for extended periods.
2. Water Resistance
The NT101 has an International Protection Rating of IP6X, meaning it is dust-tight and protected against strong jets of water. While it is water-resistant, avoid submerging the device in water or exposing it to high-pressure water streams for prolonged periods.
3. Cleaning
Clean the tail light and remote control with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the device's surface or internal components.
