The REX01 intelligent bicycle rear light is an innovative rear light for bicycles that is equipped with advanced functions to increase cycling safety. It has integrated sensors that recognise brakes, light conditions and vibrations. In the event of a stop, a red warning light is automatically activated for two seconds to warn other road users. Smart mode recognises movement and switches the light on in the event of vibrations, while it switches off automatically after two minutes of inactivity. In addition, the light sensor ensures that the rear light is switched off during the day to save energy and is reactivated in the dark or in tunnels. The wireless remote control supplied makes it possible to set indicators and change light modes without taking your hands off the handlebars.
