the bicycle's grandfather, a pedal-less wooden ego trip you scooted along like a toddler

means A draisine is an early two-wheeled vehicle propelled by pushing your feet against the ground, or — in railway use — a small auxiliary handcar or motorized rail vehicle used for inspection and maintenance.

from Named after its inventor, the German Baron Karl von Drais, who unveiled his pedal-less running machine in the early 19th century; Germans called it the Draisine and the French borrowed it as draisienne. The same name later drifted onto small rail trolleys, the word having long since outlived the wooden contraption that earned it.
