The G3 model offers a powerful superbright LED output that ensures your presence is known from a significant distance. It features an intelligent motion sensor that automatically activates the light when movement is detected and powers it down after a period of inactivity, making it an exceptionally efficient choice for busy commuters.

Safety is enhanced by the deceleration flash feature, which acts as a brake light by detecting the physical slowing of the bicycle. This immediate visual feedback is crucial for preventing rear-end collisions in urban environments. The IPX5 waterproof rating guarantees that the light will continue to function perfectly through rain and road spray.

This USB rechargeable unit is designed for easy mounting and removal, allowing for quick transitions between bikes or for taking the light inside for charging. The durable construction and reliable electronic sensors reflect a commitment to quality, providing a consistent and bright safety signal for every ride you take.
