Tsmeu-6 personal wheel bike

The  Tsmeu-6 Personal Wheel Bike is a Separatist ground craft resembling a giant wheel, with four clawed legs hanging from the sides. It could roll on the ground at great speed, crushing enemy soldiers in its path. The legs were engaged whenever the craft needed to climb steep cliffs, especially useful on the sinkhole-filled planet of Utapau. The driver was positioned in a seat on one side of the wheel, while a twin-barreled cannon occupied the other side.

General Grievous used a wheel bike while being pursued by Jedi Master Obi-Wan Kenobi, who had been sent on a specific mission: to either capture or kill the General.
