The NSC Cado Motus Neo Transformer Frame allows for a 4 wheel set up with smaller wheels and also allows for a 3 wheel configuration with bigger wheels which allows you to adjust with an increased skill level.
Choosing the right setup is always a personal choice. Besides choosing the number of wheels you can also change the wheel diameter. With so many choices, you just need to experiment. And it's exactly this that makes the Neo Transformer the perfect frame for younger skaters that keep changing physically and technically.
