This assumes that it's completely impossible to not hit your head when you fall on your side. Which is blatantly not true. This isn't a three-wheeler bike which is much harder to tip over. It's just a two wheeler that's longer. I can attest from personal experience that if you fall sideways, chances are you'll crack the side of your skull open. I got into a bike accident where someone T-boned me and if I hadn't had the helmet on, at the very least I'd have a concussion The idea that you don't need to wear a helmet cause you won't fall over the handlebars is nonsense
