Morphology

unmotorized = motorized (transparent) = un + motor + ize + ed

The meaning is directly compositional: 'un-' negates 'motorized', yielding 'not equipped with a motor'.

Etymology

Unmotorized is built from the prefix un- meaning 'not' and motor meaning 'engine', the same motor you see in motorbike or motorboat. So unmotorized means 'not using a motor', like a bicycle, a sailboat, or a scooter you push.
