A follow-me tandem (which couples a kids bike to your bike) is a much better solution than giving a 9yo a poorly controlled motor.
replyYes, we already have this (Follow-Me - the swiss company). However, my 9yo and his bike is too heavy for that. I was able to carry/drag his bike from about 3y till about 6yo.
replyNo it's not, it teaches the child dependence on the adult instead of giving the child agency.
replyBut a 9 year old is dependant on their parents ...?
reply...yes? The child bicycling their own bike, vs being attached to the parents bike is a tiny bit of independence to grant a child at that age.
