Eli5: Why do speed wobbles happen on bicycles travelling around 40mph or higher?
In: 8
Regulations on car safety and design could probably fill many large books, and for good reason – all the accidents and deaths over the last hundred years prompting said regulations to improve vehicles in an effort to reduce accidents and deaths.
Bicycles are just required to have brakes that meet a specified performance level, non-sharp edges, no loose screws/bolts/nuts, protected cables controlling shifting/braking, and no dangerous objects/”protrusions” near the crotch area. That’s it. No testing to make sure that the bicycle is machined and assembled well enough to perform at high speeds. Some manufacturers will do this themselves, but it’s not required of them.
