"While persons injured using E-bikes were more likely to suffer internal injuries (17.1%; 95% CI 5.6 to 28.6) and require hospital admission (OR=2.8, 95% CI 1.3 to 6.1), powered scooter injuries were nearly three times more likely to result in a diagnosis of concussion (3% of scooter injuries vs 0.5% of E-bike injuries). E-bike-related injuries were also more than three times more likely to involve a collision with a pedestrian than either pedal bicycles (OR=3.3, 95% CI 0.5 to 23.6) or powered scooters (OR=3.3, 95% CI 0.3 to 32.9), but there was no evidence that powered scooters were more likely than bicycles to be involved in a collision with a pedestrian (OR=1.0, 95% CI 0.3 to 3.1). While population-based rates of pedal bicycle-related injuries have been decreasing, particularly among children, reported E-bike injuries have been increasing dramatically particularly among older persons.
"Conclusions: E-bike and powered scooter use and injury patterns differ from more traditional pedal operated bicycles. Efforts to address injury prevention and control are warranted, and further studies examining demographics and hospital resource utilisation are necessary."
So the issue with e-bikes (assuming we use this as evidence) is that older people on e-bikes are the real threat---not young kids getting crazy. {"While population-based rates of pedal bicycle-related injuries have been decreasing, particularly among children, reported E-bike injuries have been increasing dramatically particularly among older persons."}
So ... does this mean fewer children are riding pedal bikes? Or that more kids are riding e-bikes but n0t pedal bikes, and are not crashing? Or are kids learning how to ride pedal bikes at an earlier age and thus having fewer accidents, while old people are not able to learn how to ride e-bikes.
Also the earlier study said the old people were more likely to have abrasions ... and this one says that "powered scooter" accidents are more likely to cause concussions. So ... are the old people on e-bikes hitting pedestrians at low speeds and falling over, causing abrasions?
As far as speed is concerned, as I keep saying every MUP and every public road has a posted speed limit. Whether they are enforced has nothing to do with whether a person pedals or does not pedal a bike.
As far as Force=Mass*acceleration ... yes, and the person was trying to concoct some ridiculous formula to limit how fat a person could ride what sort of bike.
If you cannot tell a bad idea when it screams at you, you should become a politician and write regulations ... judging by a lot of the laws and rules in place, they were written by people who similarly could not recognize bad ideas.
I never said mass times acceleration did not equal force. if you read that, go back and read again. if you are pretending that, in order to win an argument, go learn honesty.
Anyway ... carry on with your e-bike-of-doom nightmares. Not sure why you're so invested ... sorry if an e-bike touched you inappropriately.
