About this item

Stable Magnetic Mounting - Tool-free magnetic attachment ensures quick, secure installation without screws. High-strength magnets keep the bike rear light firmly in place even on bumpy rides, eliminating vibration-related loosening

Smart Dual Mode Operation - Double-tap button switches between auto/manual modes. Auto mode activates motion-sensing tech – lights off after 2 stationary minutes, reactivate via vibration for optimal energy efficiency during commutes or stops

7 Versatile Lighting Modes - Cycle through Simple Flash (36h47min), Double Flash (27h27min), Rapid Flash (13h51min), Waterdrop Flash (31h14min), Breathing Flash (12h42min), Back-Forth Flash (13h16min), and Steady Light (8h3min) with one-button control

Brake Induction Safety - Automatically triggers high-brightness mode (200m visibility) when detecting sudden deceleration, maintaining intense illumination for 1.5 seconds to alert vehicles/pedestrians, enhancing nighttime cycling security

IPX6 Waterproof & Battery Smart - 400mAh battery supports extended rides with low-power alerts (30%: slow red blink; 10%: rapid blink). Rainproof construction withstands heavy showers, though prolonged submersion should be avoided
