LK-66 Lightweight Adult Bike Cycling Helmet

Ride Light. Ride Safe. Ride Fresh.

Designed for everyday cycling and long rides alike, the LK-66 Lightweight Helmet combines advanced protection, superior ventilation, and antibacterial comfort — so you can focus on the ride, not the weight on your head.

Lightweight Protection You Can Trust

Built with a PC shell + integrated EPS foam structure, the helmet effectively absorbs and disperses impact energy, reducing direct force to the head in the event of a collision.
Certified to EU CE and GB safety standards, it delivers reliable protection backed by professional testing.

Only About 240g — Barely There

Weighing approximately 240g, the LK-66 significantly reduces head and neck fatigue.
The 20-vent airflow system channels fresh air through the helmet, accelerating heat and sweat evaporation to keep your head cool and dry throughout the ride.
