There is a fine balance between instilling the ability in a child to become independently mobile while still maintaining influence over said mobility. In that, note how these tricycles are not gear-and-chain driven, but rather “shuffle-powered” (or, alternatively, “[grand]parent-powered”). On the continuum from “walking” to “riding a bicycle”, does this particular stage of child-mobility exist in your context? Consider the cultural-specificities that make this (and similar child-mobility devices) a common sight in China, and think also about the comparable extent of parent/guardian control exerted over such a vehicle in your context (and the child’s varying degrees of acceptance of said control).
