Park and Diamond Foldable Bicycle Helmet


The Crowd Funding Source Indiegogo is helping to fund a new exciting product. Park and Diamond has made a foldable bike helmet that looks like a baseball cap. And it is safer than a traditional helmet. It will be manufactured in Europe and the United States. The bad: looks like it may be assembled in Asia.

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.
