XNITO Electric Bike Helmet with LED Lights - CPSC & NTA-8776 Dual Certified - Class 3 E-Bikes, Bicycle, Scooters, Onewheel, Skateboard - GULL (Medium size)

I - MAXIMUM SAFETY: The XNITO e-bike helmet is dual certified in accordance with CPSC and NTA-8776 safety standards. The helmet is designed for higher speed protection up to 28mph. It's safe to use with Class 3 e-bikes, e-scooters, e-skateboards, onewheels as well as standard bicycles. It offers greater impact absorption and additional coverage for the temples and rear of the head. A thicker layer of EPS foam provides extra crash protection.

II - BETTER VISIBILITY: Custom-integrated LED front and rear lights improve visibility up to 100% at night and in foggy conditions. They provide up to 10 hours of illumination and are USB rechargeable, lightweight, water-resistant, and feature 3 modes (flash, static, and wavy). The buttons are easy to press to switch the lighting mode with a helmet on.

III - STYLISH DESIGN: The helmet has a stylish urban look. The aerodynamic design contains 10 vents on the front and on the crest of the helmet that actively capture airflow and pass it through the interior cooling channels for better ventilation. In-mold construction weighs less than a pound (0.83 lbs), which helps reduce sweating and heat during long rides. The detachable fabric visor protects the eyes from the sun.

IV - PERFECT FIT: Ensure the helmet fits snug to your head with our dial-fit wheel. Currently, large size fits most adults (22.8 - 23.6in), medium size fits smaller heads from 21.2 - 22.8in and the extra-large size fits bigger heads from 23.6 to 25in.

V - LIFETIME WARRANTY: We are 100 % sure of our product! We offer a lifetime guarantee to replace the helmet for free if you are involved in an accident that results in damage to your helmet.
