Yes, they do, as the name would suggest, complete skateboards come with all the components you need to pick it up and skate. However, the thing you will find with complete boards is that the components used won’t be of the highest quality. They will usually be the bearings that aren’t selling too well or bearings that come from a less reputable brand. Which means that they won’t last that long. So if you do opt to purchase a complete, certainly skate the bearings until they are shredded to bits, but make sure you have a quality set on standby.
