What it is

On December 3, 2001, Kamen unveiled this self-balancing two-wheeled personal transporter, capable of up to 10 mph thanks to gyroscopic sensors that keep it balanced. It grew out of the self-balancing iBOT wheelchair Kamen had developed earlier.

Production of the original Segway PT ceased in 2020.

What it led to
