Bearing is one of the most important parts of a stunt scooter. They have a significant impact on the quality and speed of the ride. Stunt scooters use special impact-resistant bearings, do not use regular bearings or those for roller skates.
The quality of the bearings is assessed and examined by the normalization committee of bearings in the USA Annular Bearing Engineering Committee, abbreviated as ABEC. The ABEC standard indicates only the precision of the bearing manufacturing, not the material and smoothness of the ball surface in the bearing, so we can find that bearings with a lower ABEC grade perform better. Generally, with branded manufacturers, the higher the ABEC grade, the better the bearings perform.
