Bearings are one of the most important parts of a scooter. They have a significant impact on the quality and speed of the ride. Special impact-resistant bearings are used in scooters; do not use regular bearings or those meant for roller skates.
The quality of bearings is assessed and tested by the bearings normalization committee in the USA Annular Bearing Engineering Committee, abbreviated as ABEC. The ABEC standard only indicates the accuracy of the production of bearings, not the material and smoothness of the balls in the bearing, so it is possible to find that bearings with a lower ABEC grade perform better. Generally, with brand manufacturers, the higher the ABEC grade, the better the bearings will perform.
