A "beginner" scooter lets the rider learn the basics of freestyle scootering.
And "intermediate" scooter lets the rider develop and evolve with the same kit.
An "expert' scooter' lets the rider practice every type of scootering.
Weight is important when choosing a scooter.
The smaller the size of the rider, the more important it is to have a light scooter. It will be much easier to do tricks.
Weight becomes less important when the rider is bigger.
