CYCLAMI CY120 Smart Brake Bicycle Taillight with Auto Start/Stop: Auto brake sensing activation
For the urban commuter navigating busy streets or the evening rider on dimly lit paths, the CYCLAMI CY120 Smart Brake Bicycle Taillight is your reliable co-pilot. While most bike lights focus on visibility, this one adds a layer of intelligent safety that anticipates your needs.
The brake-sensing feature activates maximum brightness instantly when you slow down, alerting drivers behind you before they even notice your movement. In a real-world test, the vibration wake-up function proved invaluable after a brief stop at a café—it resumed flashing automatically as you pedaled away, no fumbling required. With six lighting modes, you can choose a steady glow for city rides or a dynamic pattern for extra attention on rural roads.
Its IP65 waterproof rating means rain won't interrupt your journey, and the energy-saving mode adjusts brightness based on ambient light to extend battery life up to 40 hours. Weighing just 27g, it mounts easily with included brackets, making safety seamless for every ride.
