Meet the Robstep RoadRunner M1: a self-balancing transportation device that helps you get around with less effort. It can move forward, backward, stop, and turn. It has a range of 12 miles per charge and a max speed of 10 miles per hour. The handle is adjustable, which helps.
Robstep comes ready to roll and can be put in the trunk of a car when you are done. This zero-emission transporter is not super cheap though.
