Buying scooter wheels

Every wheel needs 2x bearings and 1x spacer to function.
Wheels are made in different materials, dimensions, hardness, profiles and different cores.

The illustration tells you what is what.


  • Solid core. Massive core for maximum durability.
  • Spoked core. Core with holes and cutouts. Makes a lightweight wheel, but also weaker!
  • Hollow core. Hollow inside for lightweight, while still maintaining strength. (Not as strong as solid core)
  • Plastic core, Not pictured. Plastic cores do not last long, and are a bit flexible.


  • Flat profile (A flat profile that gives strength to the rubber and maximum grip)
  • Narrow profile ( A narrow profile gives you speed)


  • The durometer scale goes from 0-100a, where 100a is the hardest. Most scooter wheels are 85a.
  • Hard wheels last longer, they are more slippery but are also faster!
  • Soft wheels wear down faster, but have a good grip, great for parks and indoor use.
  • Not all manufacturers inform the wheel hardness, then just try it out.

Mounting bearings into wheel


  • Always make sure the bearings are 100% aligned with the core, if not the bearing and wheel core will brake.
  • No wheels are harder than asphalt, so blocking a rubber wheel will always create a flatspot.
  • Always replace your wheels when worn down, for your own safety but also so you dont destroy the Flex fender brake!
