S1 lights and safety alerts
Front and rear lights, left/right turn signals, fall detection, and auto brake alert behavior.
S1 includes front and rear lights plus left and right turn signals for urban riding visibility.
The light modes are steady, fast flash, and slow flash. Typical runtime is about 4 hours in steady mode, 8 hours in fast flash, and 18 hours in slow flash.
The automatic brake flash alert uses the rear light to improve visibility when sudden braking is detected.
Fall detection is included as a support feature. After a strong impact, inspect the helmet carefully and contact support before continuing use.
