Dicycle

Originally used to refer to devices with large wheels and pedals, the term is now used in relation to powered self-balancing scooters with smaller wheels and no pedals such as the Segway PT and the self-balancing hoverboard.

[6] The Segway PT is a two-wheeled self-balancing personal transporter which uses computers, sensors, and electric motors to keep the device upright.

The diwheel design has the two large outer wheels completely encompassing an inner frame.

All of these platforms suffer from two common issues affecting driver comfort; slosh and tumbling (also known as gerbilling).

It is very prevalent as these platforms typically have low damping between the wheel and the frame, to minimise power consumption during locomotion.
