I bought a euro playsafe trike to my 23m old girl recently.
It is suitable from 18m to 6yrs (adjustable seat with seatbelt).
It has a parent bar which I can push her and footrest that she can put her feet up if she doesnt want to push the peddles.
She loves it and I m very happy about it.
Not sure whether you have it in HK (made in China).
