I've always encouraged younger or inepexerienced riders to buy/use a decent spec flat bar hybrid, IMHO there's absolutely no reason whatsoever to buy a drop bar bike at that age unless they're racing. Widens the choice of available bikes/frames, easier to control both on and off road with flat bars for the lesser experienced/younger rider,more options for wider tyres and have utility value as well.
