Complete Front and Rear Visibility for Night Riding

Why Riders Choose It

1800-Lumen Front Illumination

The front light uses six high-performance LED beads and delivers up to 1800 lumens of brightness, helping riders see roads, bike paths and low-light surroundings more clearly.

Four Headlight Modes

Choose from Low Beam, High Beam, Low + High Beam and Flashing modes to match different riding environments and battery needs.

Smart Brake-Sensing Tail Light

When braking or deceleration is detected, the rear light automatically increases its brightness to help alert vehicles, pedestrians and cyclists behind you.

Automatic Light and Motion Detection

Built-in light and motion sensors support automatic on/off operation. Vibration activation and automatic sleep mode help reduce unnecessary battery use when the bicycle is not moving.

Six Taillight Modes

The smart rear light provides six lighting modes for commuting, daytime visibility, night riding and different traffic conditions.

Rechargeable Battery System

The headlight is equipped with a 4000mAh rechargeable battery, while the tail light uses a 500mAh rechargeable battery.

USB-C charging provides convenient everyday recharging, and the battery indicator helps riders check the remaining headlight power.

Flexible Tail Light Installation

The package includes both a saddle mounting kit and a seat-post mounting kit, allowing riders to choose the installation position that works best for their bicycle.

IPX4 Water-Resistant Design

The front and rear lights are designed to resist light rain and road spray during normal riding conditions.

Do not submerge the lights in water or expose them to heavy rain for extended periods.

Fit and Compatibility

Suitable for most road bikes, mountain bikes, hybrid bikes, commuter bikes and e-bikes.

This is an independently rechargeable USB-C light set. It does not require connection to an e-bike controller or wiring system.
