The best children’s bike is a lightweight  bike.
Children and especially small children do not have such a good balance and they do not have such strong muscles compared to an adult.
The finest children’s bike is a lightweight children’s bike. ( for adults too).
A normal steel Dutch bicycle is about 2/3 of the body weight of the child. An aluminum bicycle is 1/3 of the body weight of the child. Dutch 16-inch bicycles weight 12-15 kg for a 3- 5 year old child. For an adult of 75 kg that is 50 kg. That does not weight your bike during a camping holiday!
Such a steel bike  your child hasnot under control and then easily drags your child into the trap. They are unsafe.
With a lightweight bike, your child can ride longer distances, gets on more easily, starts faster, can cycle harder and gets on a hill more easily.
The Woom children’s bike 16 inch weighs 5.7 kg. A Frog bike weighs 6.75 kg.
In the case of lightweight bikes, the ratios are generally good too. Such as small handles and small brake levers, so that the small fingers can good at the brakes. Short cranks, small saddles and a not too wide handlebars.

All the Dutch bikes have too long cranks, that makes cycling heavy, it is also a too heavy load for your knees.
