The Lumos Ultra is equipped with a range of intelligent safety features that make cycling safer. These include integrated turn signals that can be operated via a remote control or manually with the Apple Watch. By default, the Ultra comes with built-in front and rear lights for better visibility. Thanks to the improved COB construction technology, the helmet weighs only 370 g. However, the lighting is brighter than in other Lumos models. The Ultra now has a battery life of over 10 hours, and the headset is charged via a USB-C cable.
