Co-founder David Hall's sister was riding her bike through the intersection of Park & Diamond when she was the victim of a hit and run accident. She spent the next four months in a coma. While she has since recovered and graduated from college, Dave and Co-founder Jordan Klein quickly learned that Dave's sister was one of 85,000 Americans to suffer a traumatic brain injury from cycling-related accidents that year.

So David and Jordan asked: "How can we make cycling safer?". After three years of development, the new Park & Diamond helmet will answer this question!



The Park & Diamond helmet will pass all U.S. and E.U regulations to make sure you get the protection you need while riding a bicycle or kick scooter. Adult sizes will be available first.  


When a traditional bike helmet bounces, the EPS foam protective material releases the energy back to the users head during impact increasing the total momentum change the wearer experiences. With this greater momentum change, there is a greater likelihood of a head injury.

The Park & Diamond Bike Helmet’s patented protective material absorbs and dissipates three times more elastic energy than a traditional bike helmet, which means significantly less energy is being transferred to the head, and making the Park & Diamond Helmet a better bike helmet.

The Park & Diamond helmet was designed using patented and proprietary protection materials that are significantly more efficient at absorbing and dissipating energy than traditional bike helmets, It folds/rolls-up into a unique cylindrical case, and has washable and interchangeable skins.

* The Park & Diamond™  Helmet is designed and engineered to comply with  U.S, Canada, andEuropean Union cycling safety standards. On delivery, Park & Diamond will comply with U.S. Consumer Product Safety Commission (CPSC), Canada CAN-CSA-D113.2-M, and the EU EN-1078 safety certifications. “Safe as a traditional helmet" safety claim is based on Park & Diamond's compliance with these regulations.


"We see a world without life-altering brain injuries and will relentlessly work to create this reality."

"Building more than a brand, a product, or a company, Park & Diamond sees a barrier-free ecosystem of protection for every lifestyle."

A project three years in the making with the support and recognition from engineering and technology communities. We are fully prepared to deliver.
