1. 7 COLORS & 15 LIGHT MODES

Press and hold the button for 2-3 seconds to turn on the children's bicycle rim light. It will automatically start in 7-color changing mode. A short press lets you switch between single colors, constant light, or various flashing modes. Choose green, red, blue, pink, cyan, yellow, white, or 3 different multi-modes—perfect for showing off your own style while being highly visible in traffic.

2. HIGH-BRIGHT LEDs

The ROCKBROS LED rim light consists of 12 bright RGB LEDs, ensuring you are clearly visible from all angles—ideal for night rides. Thanks to motion and manual sensors, the lights switch on automatically as soon as movement is detected and switch off again after 30 seconds without movement. 3. EASY INSTALLATION Installation is super easy: simply stick the appropriate hub pad size (6 pieces included) onto the inner rim – no tools required. Please check the hub diameter beforehand; the light fits hubs with a diameter of 30 mm / 1.18 inches. 4. USB RECHARGEABLE With an integrated 300 mAh lithium battery, rechargeable via USB – no additional batteries needed. The spoke lights last up to 18 hours in flashing mode, 9 hours in continuous light mode, and 7 hours in automatic color-changing mode. Saves money and protects the environment.

5. WATERPROOF & DURABLE

Made of high-quality PC material, robust and suitable for bad weather. No need to worry in the rain – however, please do not fully submerge it in water.
