Momo brought the first bike trainer for his nephew WeiKai who is 3 year old to ride. I was very proud of her when she gently shared/demo Kai the tricks. The little boy was thrilled and I am sure he will have lots of fun learn to ride.
The first rider is learning bike without pedals. Yes, its a luxury but it really helps due to the light weight and adjustability of the seat... can be lowered really low. Have a look at how momo learned here
