My daughter did 2 years (thereabouts) on her Piaggio NRG 50cc , it is much easier to learn to ride on one with it being a auto....much like riding a pushbike with having to pedal. ....a car took her fancy after riding home from nightshifts in shit weather, she did once push the scoot home a distance of nearly 2 miles when the roads were covered in snow & ice....wise decision.
My lad has never shown any inclination to ride or drive, he has never had a driving licence....he did have a nice mountain bike at one time, but he sold it when he ran out of Fosters one day.
Good work with your daughters lessons. š
