Buckle the helmet, not just the belt
A helmet hanging from the handlebar cannot protect your head. The published estimate is for motorcyclists, not electric-bike riders.
Wear a helmet and fasten its strap before a motorcycle or electric-bike trip.
Motorcycle helmet use was associated with lower death odds: OR 0.58 versus no helmet.
Why consider it?
The Cochrane review pooled observational motorcycle-crash studies. OR 0.58 means lower odds, not an absolute percentage-point reduction. Applying the action to electric bikes is the book's extrapolation; the review did not directly establish an electric-bike effect.
