Does the number on the product side indicate the size?
The number on the product side is just design. The size is indicated by the label (Mini or Maxi) on the instruction manual. Additionally, the size is also engraved in the product behind the rear wheel.
The motorcycle is very loud. Would it be possible to put tires on the wheels?
It is important to understand that the answer to this is clearly NO. On the one hand, the strict regulation itself does not allow manufacturers to use tires in the case of such young children. But the most important thing is that, when sitting on the motorcycle, the child is sitting under our viewing angle so for their safe movement it is essential that, by the sound, we are aware of where they are!”
