The Onewheel is an electric skateboard that you can control with your body. To control the Onewheel you lean forward to go faster and lean back to slow down. Also to go side to side you just lean that way. The onewheel uses the motion sensing technology also used in a smart phone and it uses the motor and battery technology found in a Tesla. Kyle Doerksen is the inventor of the one wheel.

This relates to engineering because it uses technology which you can find in phones and a Tesla. Also it uses engineering because it only has one wheel.
