The AURA 50 is more than just a light – it is your smart companion for everyday life in the city and beyond. With 50 lux and a beam range of up to 60 metres, it gets you safely to your destination, whether to the office in the morning or home in the evening. Thanks to the automatic brightness sensor, it adapts to the lighting conditions for the perfect balance of visibility, efficiency and freedom on two wheels. New: with the USB-C connection, the AURA 50 can now be charged even faster and more conveniently – ready for every new adventure.
The AURA 50 has two light modes. In High mode it reliably illuminates your path for up to 9 hours, and in ECO mode for up to 28 hours. Thanks to the memory function, the AURA 50 switches on next time in the same mode it was in when you turned it off.
