that front carrier is complete garbage. Completley idiotic and dangerous. If something even slightly hinders your maneuverability then your risk of not saving yourself from a crash that would have been easily avoided before is significantly higher.
Dont sacrifice safety for a slight increase in your perception of your childs enjoyment.
Next these tools are going to design a childseat to mount in front of the handlebars or on the hood of a car.
Think lifesaving in a water rescue, you sacrifice all of the victims comfort to allow you to have as much control as possible, even putting the victim in between you and rocks/pilings because if you are also hampered then the risk is much greater to both of you.
The real question is how is this even a question, its your childs safety.
