Oldest sister is a super-genius hippie that would ride some type of U0- 8 variant with some crazy gearing system controlled by plants.

Middle sister, lawyer would ride a Orient, chauffeur driven on busy days.

Youngest sister (still older) mother/exec would not ride but she would drive along side in a car and scream orders to pedal harder.

Younger brother would ride a Harley or Indian with steel pipes bent into circles for tires, a gun turret, beer holder and place for his ***** (b word).
