ROCKBROS Q1 Rear Bike Light with 7 LED Colours, USB-C Charging, IPX6, 30 Lumens, Black

Cycling after dusk on busy city streets demands visibility. The ROCKBROS Q1 rear bike light mounts in seconds and keeps you seen with seven vivid LED colours and eight lighting modes. Its COB LED strip delivers 30 lumens of brightness, visible from up to 1000 metres away, while the IPX6 waterproof rating shrugs off heavy rain. A 300 mAh rechargeable battery powers up to 50 hours of runtime, and the included USB-C cable recharges it in about 1.5 hours. The tool-free silicone strap fits most seatposts, and the low-battery indicator ensures you're never caught off guard.
