So, I’m guessing that’s not a road legal ebike but hes just filmed himself riding it unrestricted on a road well over 15.5 mph. Anyone reported it to the police?
IIRC someone got done recently from one of the scooby forums for a video they posted of driving over snake pass. The police went out and measured the distance between landmarks to prove he was averaging over 80mph for sections of it.
n.b. it’s not a speed limit, or even an electronic limiter, it’s the speed at which the assistance has to cut off. So while blatant, actually proving it might be harder. Easy enough to deny it in court and claim the figures were exaggerated for publicity and if the bike was accelerating past 15.5mph he was pedaling or riding downhill.
