Wheel Bike

General Grivous' reputation as a merciless military leader is fearsome, and his personal fleet of specialised killing machines and vehicles reinforces this. On cavernous Utapu, the cyborg General drives a wheel bike-a tumbling twinwheel that sorrounds a central motor. Grevous military vehicle is an offshoot of the hoop-well halifire droid,designed to roll at intimidating speeds on hard surfaces. It can also stand and walk on two pairs of legs to avoid smouldering battle wreks and other obstacles. The wheel bike is put to the test when General Kenobi, astride the Utapaun dragon Boga, purses the cyborg on a dangerous chase  through the chasms of Pau city.
