Bryton Gardia R300L cyclo radar

The Bryton Gardia R300L effectively combines the functions of a rear bicycle radar and a rear light, significantly helping to prevent the rider from colliding with a vehicle approaching from behind. When a vehicle approaches the cyclist from behind, in addition to the radar alerts on the compatible bike computer display and in the Gardia app, the Bryton Gardia R300L will automatically change the taillight mode to alert the driver of the approaching vehicle.
Product features
Detects approaching vehicles up to 190 meters away
Visual and audible warnings of vehicles approaching from behind via compatible bike computers
Automatically evaluates the cyclist's threat level and activates the taillight warning mode based on relative speed
Can optimize the intensity of the rear light in cooperation with a paired Bryton cycling computer with an integrated light sensor
Detects braking thanks to the built-in G-sensor, which activates the brake light function
Integrated ANT+ wireless connectivity allows you to create a network of compatible front and rear lights, controlled directly from cycling computers
Displays current battery life on the display of a compatible Bryton cycling computer or in the Bryton Gardia app
The taillight automatically dims when the battery life is low.
