Review on AOWISH 120mm Light-up Scooter Wheels Pair - LED Flashing 120mm Replacement Front Wheel for 3-Wheeled Kick Scooter with ABEC-9 Bearings - Ideal for Kids Foldable Micro Scooters by Eric Grayson

I bought thinking I could cut out the center plastic hub and mount it on the outside of a wheel on a unicycle scooter. The problem for me was in the inner metal hole of the disk axle. The 100mm wheels are slightly smaller than the bearing OD, so I wrecked one by trying to cut out the entire area of the plastic hub. I'm assuming this 120mm model is similar as the inner metal hub posts extend to the outer bearing seal. How far I'm not exactly sure, but I feel it's very close to the OD of the bearing. Posted this information for anyone considering a similar project
