What it is

The UNIT 1 AURA Mips represents a significant shift in urban safety gear by blending high-speed protection with an active lighting ecosystem. Unlike standard road helmets, the AURA is built to meet the NTA 8776 standard, meaning it provides superior impact protection for riders on e-bikes reaching speeds up to 28 mph. The 500-lumen integrated lighting system ensures you are visible from all angles, creating a safety perimeter that passive reflectors simply cannot match. Beyond basic visibility, this helmet functions as a connected piece of hardware. When synced with the proprietary app, users can customize light patterns and set up SOS alerts that notify emergency contacts in the event of a crash. The physical build is equally premium, featuring a Fidlock magnetic buckle for effortless one-handed use and a MIPS liner to reduce rotational forces during an impact. While the weight is slightly higher than a traditional racing helmet, the balance and ventilation make it comfortable for daily metropolitan travel.

Ravvy AI insight

The AURA is a strategic investment for those who prioritize active safety over weight savings. While the initial cost is high, the inclusion of NTA 8776 certification and 500-lumen lighting replaces the need for separate high-powered clip-on lights. To get the most value, we recommend purchasing the optional remote to unlock the turn signal functionality, as the gesture-based system is less intuitive than a tactile switch.

Download the UNIT 1 app immediately after unboxing to configure your emergency contacts. This ensures the crash detection sensors can actually send a help message if you suffer a hard fall.

Ownership tips

tip

Maximize Battery Life

Use the pulse or flash lighting modes rather than steady-on for daytime riding. This significantly extends the interval between charges while still maintaining high visibility to drivers.

care

Port Maintenance

Ensure the USB-C charging port cover is fully seated after every charge. Keeping this seal tight prevents moisture and road grit from damaging the internal electronics during rain.
