Protecting her noggin is my #1 priority. ❤️

When my wife Patricia suffered a traumatic brain injury, everything changed.

My first decision was simple:

If she was going to ride again, I would do everything I could to protect her head.

So in 2025, I researched independent testing and chose what was, at the time, the #1 rated helmet available.

She loves it. It fits perfectly, and we both felt confident knowing she had the best protection available.

Unfortunately, I fell short in caring for the helmet. It had been stored and kept in the car, and I began to worry that it may have been compromised.

So that brought me back to looking for a new helmet.

When I saw the new PIKIO Si OBLIK testing even better, I had to try it.

Today was her first ride in it, and she praised the fit, comfort, airflow and appearance.

And I feel better knowing she’s now wearing a helmet that tested significantly better than her older one, which is still an excellent helmet but is now ranked #13.

When it comes to Patricia’s safety, I can’t settle.

I was actually going to order one for myself too… but I had the last one in my cart. 😂

So, obviously, Patricia won that battle. ❤️

Protecting her noggin is just part of the job. 🚴‍♀️❤️

Welcome to the family, PIKIO Si OBLIK.

Harold, thank you for sharing Patricia’s story with us. It means a lot to know that the thought and care we put into the Si OBLIK gives you both greater confidence on the road. What you’ve both been through is incredibly difficult, and we’re so happy to see Patricia able to continue enjoying the rides.

We’re so glad to hear that she is enjoying the fit, comfort, airflow, and design. She may have won this time, but hopefully you can pick one up for yourself soon!

Not just the safest helmet but great all around. Super comfortable, and well thought-out, with usable sunglass storage. Disappears on your head!

Thank you, Nathaniel! We’re thrilled you’re enjoying the fit, comfort, and thoughtful details. We took a holistic approach and put a lot of care into making every part of the helmet, so it means a lot to hear this.

360° Impact Management

Our patented OBLIK impact system technology enables each modular component to move omni-directionally. This movement allows the cycling helmet to respond dynamically to impacts from any angle, helping manage both rotational forces and linear forces more effectively for enhanced impact protection.

Superior Ventilation

17 precisely positioned vents and deep internal channels create a controlled airflow path that draws cool air in and efficiently evacuates heat. The ventilation architecture is integrated into the shell to maintain aerodynamic integrity.

Dual Density EPS Foam

Impact forces vary in intensity, and helmets with single density foam are often less effective at managing the moderate impacts that occur most frequently. By integrating dual density EPS foam, our helmet responds to a broader range of impact energies for more consistent performance.

Macro Cavities

Through extensive research in impact mechanics, shock absorption, and bone structure, we discovered that combining micro cavities within the foam with larger macro cavities significantly enhances impact energy absorption. The result is an advanced helmet structure engineered to optimize how a helmet responds to real world impact forces, delivering substantially improved energy management compared to traditional constructions.

Reinforced Layers

EPS foam is inherently fragile, making careful design essential for structural integrity. By integrating a strategically placed polycarbonate reinforcement layer, we increased strength while reducing material, resulting in a lighter, more robust helmet.

Holistic Design in the PIKIO Si

The PIKIO Si is built on a holistic design approach, where every element of the helmet is engineered to work in harmony. By balancing impact protection, ventilation, and lightweight construction, each component contributes to an integrated system, ensuring that improvements in one area never come at the expense of another. The result is a helmet that delivers optimized performance, comfort, and efficiency for the rider.
