Smart USB rear bike light with brake sensing, 12 light modes, group sync, and IPX6 waterproof rating. Rechargeable and ideal for MTB or road cycling safety.

Enhance your cycling visibility with this smart rear bike light featuring brake-sensing technology and multiple intelligent modes. Designed for MTB, road bikes, and group rides, this compact tail light offers high visibility, safety, and convenience in one durable package.

Built with a rugged aluminium alloy and ABS+PC body, it’s fully IPX6 waterproof—ideal for riding through rain or splashes. The smart brake sensor detects deceleration and automatically brightens for 3 seconds, alerting vehicles and riders behind you. A light sensor conserves power by switching off in bright conditions and back on in low light.

With 12 lighting modes and a sync mode for group rides, this light allows seamless matching with other lights within 50 metres. The gear memory function remembers your last setting, and the auto sleep function powers down after 30 seconds of inactivity, waking with vibration for energy saving.

The light charges in about 2 hours using the included USB cable and features dual mounting options for seatpost or saddle rails. Compact yet powerful, it ensures visibility, safety, and convenience whether you ride solo or in a pack.
