Why are treadmill only able to go 12 mph?
In: Engineering
Even leaving aside reasonable use cases for a treadmill and assuming there are a lot of people out there who want to run faster, it wouldn’t be safe on a standard treadmill frame. If someone using a treadmill pauses or stumbles, they have until the tread rolls around the back to compensate, or else they fall off and potentially hurt themselves. The faster the treadmill is going, the shorter this grace period is. Eventually it starts to get shorter than a reasonable human reaction time. At that point, your options are either to cap the speed or make the treadmill longer.
