• 🚲【All-in-One Smart Tail Light with Remote Control】 Unlike ordinary bike lights, this device combines a tail light, brake light, anti-theft alarm, remote control, and bike bell in one compact and powerful unit. With a 98–196 ft wireless range, the remote lets you switch light modes, sound the bell, or activate the security alarm — all at your fingertips. Whether you're cycling in traffic, parking at a café, or riding at night, this is your all-in-one visibility and protection tool.
• 💡【Smart Brake Light & Intelligent Auto On/Off】 Stay safer on the road with the 3D displacement sensor and advanced smart chip. The light automatically switches to high-brightness mode for 2 seconds when braking, alerting vehicles behind you instantly. In Smart Mode (Slow Flash / Breathing Light), the system automatically shuts off in daylight or when idle for over 30 seconds, and wakes up as you ride. No need to fumble with buttons — your bike light thinks for you.
• 🔋【USB-C Rechargeable + Ultra-Long Battery Life】 Say goodbye to constant charging. The built-in 700mAh rechargeable battery powers the tail light for 1–3 months on typical daily use, depending on mode. Recharge via USB-C for fast and universal compatibility. The remote uses a replaceable 27A battery that lasts up to 2 years (5 daily uses). This bike tail light is designed to be low-maintenance and long-lasting for everyday riders.
• 🔊【113dB Anti-Theft Alarm with Motion Detection】 Your bike deserves protection — even when you're away. This tail light doubles as a bike alarm system, equipped with a motion-sensitive sensor and a super loud 113dB siren to scare off thieves. Just one vibration triggers the alarm. Built with PC + UV-resistant housing and an IP65 waterproof rating, it performs reliably in rain, heat, and snow. One press on the remote disarms the alarm — quick, easy, and secure.
• 🔊【7-Level Sensitivity & 3 Adjustable Volume Levels】 Fine-tune your bike’s security and alerts. This tail light offers 7 adjustable sensitivity levels (from gentle to highly responsive) to suit different environments—city, park, or off-road. Choose from 3 volume levels to match your needs: from quiet alerts at night to loud warnings in crowded areas.
