"The deaths came as a result of head trauma, with at least three of the accidents happening with the rider in a helmet."
"Alongside the US Consumer Product Safety Commission (CPSC), the company now seeks to remedy the products after four known death cases — three without a helmet — between 2019 and 2021."
Actually, Adam recently achieved the scared third-degree black belt, which makes him a master of Suk-Hyeon-Deisu
Still doesn’t look like it’s enough while they cross a street in front of turning cars.
I can't speak for DOT helmets, since that standard is untrustable for a variety of reasons anyway.
ECE is a United Nations standard that the EU has chosen to require for helmets sold in the EU.
It sounds like upthread the poster thought that ECE doesn't allow half or 3/4 helmets, but they do.
- is nearly 50 years old without meaningful changes to reflect half a century of head injury and brain injury research
- has significantly lower standards for how much force can be transmitted through the helmet to your skull - well within values that commonly cause skull fracture
- does not have any brain injury criteria for rotational trauma
- does not have any independent random testing, and limited independent random test studies have found 50% of labeled helmets don't meet the standard
The last point is especially frightening! ECE has fixed all of these issues. Fortnine's videos on this (and the problems with Snell 2020R/2020D) are a great place to learn more.
I’ve had this same thing happen on a electric skateboard at about this speed but on asphalt. Shoulder dislocated, elbow broke, wrist sprain so severe I had to relearn how to use my hand. And I was a skateboarder my whole life leading up to that so I knew how to take a fall.
I still use electric bike and fat tire scooter/bike. But the high speed even on that feels sketchy. All it takes is a little gravel or something and you’ll lose your front wheel and eat it hard. That actually happened to a friend growing up, we were flying down a steep hill (ok maybe 20mph) on our BMX bikes. He hit gravel and the front wheel slid out. He had to have his upper lip stitched back on.
Couldn’t say if that was a power loss issue or the wheel just got too deep in the mud, but doesn’t look fun especially if you imagine that fall on to concrete.
