Smart Bike Tail Light with Brake Sensing | USB-C Rechargeable Rear Light for E-Bikes & Urban Commuting

Automatic Safety Lighting with Smart Brake Detection and Auto On/Off Function Designed for cyclists who prioritize visibility and safety during daily commuting and night riding, this Smart Bike Tail Light combines brake sensing technology, automatic on/off functionality, and multiple lighting modes in a compact and reliable rear light. The intelligent brake sensing system automatically increases brightness when deceleration or sudden braking is detected, helping alert vehicles, pedestrians, and other cyclists behind you. This enhanced visibility helps improve riding safety, especially in urban traffic and low-light environments. Equipped with light and motion sensors, the taillight automatically turns on in dark conditions and enters sleep mode after 40 seconds of inactivity. Once vibration is detected, the light automatically wakes up and resumes operation, providing a convenient hands-free lighting experience while helping conserve battery power. Powered by a built-in 500mAh rechargeable lithium battery, the taillight delivers up to 14 hours of runtime and supports convenient USB-C charging. Six lighting modes allow riders to choose the ideal brightness and flashing pattern for different riding conditions, including commuting, night cycling, and daytime visibility. The included dual mounting system offers flexible installation options, allowing the light to be mounted either on the seat post or underneath the saddle. Compatible with most road bikes, mountain bikes, commuter bikes, and e-bikes, it provides a stable and secure fit for a wide range of bicycles. Whether you're commuting home after work, riding through city streets, or exploring roads after sunset, this smart bike tail light helps keep you visible and protected on every ride.
