Before opening this I knew this that there'd by something from Blackburn.

I guess you're right, but I think bike helmet makers have a responsibility to their customers that they've failed utterly to meet. It was, what, 3 years ago now maybe, that we first were told that the industry was working on an updated certification standard to test for preventing brain injury not just skull fractures. Still nothing.

You may be right, of course. Maddening that, several years into increased concussion awareness we're all still stuck fumbling in the dark on all these empirically answerable questions.

It's important to be clear-eyed about what a full-face adds, and doesn't add, in terms of rider safety. It surely increases facial protection. But when it comes to concussion and brain trauma, I'm not aware of any evidence that fullfaces are better than halfshells. And they may be worse. More mass and a longer lever arm could increase direct and rotational forces on the brain vs. the same crash in a halfshell. And I wonder if hotter helmets lead to increased fatigue and more crashes. Nothing I'm saying here proves that fullfaces result in more concussions (and, to be clear, I'm neither an insider nor an expert, just a rider who had a bad concussion recovery and has paid attention to this ever since). But if you're buying a fullface thinking that it's the safer choice across the board, you could be making a mistake. I'm a lot more worried about my brain than my teeth, and my best guess from the crappy info available is that the safest option for trail riding is a modern halfshell from a company with a strong track record of concussion-safety innovation with multiple concussion-risk-reducing design features, not a fullface.

Intrigued by Vik's idea. I've had success with a different approach, buying the size that fits from the start and then, if they stretch, tightening the cuff by pinching out the excess and sewing it together. Free, fairly easy, and it works.

You're downvoting my comments, Mammal, but I more or less agree with you and didn't say anything to the contrary.

My comment was directed at nsmb's decision to publish this, not at whether trail builders should use ebikes.

The limp sales pitch at the end was the bright red cherry on top of a piece NSMB never should have agreed to run.

You'd think, but on the other hand Lee doesn't strike me as one to wing it, so who knows. I had 820s on my last bike, which seemed a little ridiculous but I loved them. Maybe he's on to something.
