Why are people wearing a helmet? It only gets up to 16km/h (10mph), and it just adds like 10cm to your height. Humans can run up to 44 km/h and Ive never seen them wearing a helmet.

It really makes the product look dangerous.

I bet it's classified as an electric bike....and lots of places require helmets for bike riders.

...or you need to use it on the road, in which case a helmet will protect you if you get buzzed by a car (or worse).
