7 Main Features

Compact and convenient to master with one hand

Small size, lightweight, easy to carry, making cycling more effortless

Brake sensing Instant Intelligent Brake Light

When a significant decrease in vehicle speed is detected, the bike light will immediately switch to full brightness for approximately 2.5 seconds to warn vehicles behind

Vibration sensing, intelligent wake-up

Three light modes for different scenarios

Long press:
Intelligent brake and vibration sensing modes activated
Double press : Turn off or turn on the brake sensing mode
Single press: Flashing, High light, LED Cyclic flashing modes in sequential rotation

Memory function, thoughtful design

The tail light has a mode memory function, so when you power it on again, you don't need to switch modes sequentially to adjust

Magnetic interface, charging only takes 2.5 hours

The charging port, which is a weak point in the waterproofing of the bike light, uses a magnetic charging method to ensure the integrity of the housing while providing simple and convenient charging. The 200mAh capacity meets daily cycling needs.

IPX7 Waterproof Rating Ultrasonic Welding Technology

The upper and lower covers are tightly welded together using ultrasonic welding technology, making it highly resistant to water penetration even on rainy days (avoid prolonged immersion in water)

Two Mounting Options for various scenarios

Equipped with two mounting brackets, allowing free choice of installation position based on different scenarios
