Review on Glow In The Dark Rollerex LED Wheels With Bearings For Inline Skates - Available In Multiple Sizes And Colors by Travis Petty

 I have never changed wheels on skates before so when I first put them on, they did not work. I realized I needed to remove the bearings from the wheels I was replacing (the ones that originally came with the skates) and put them in the new wheels. Once I figured it out they worked perfectly. My kiddo loves them! Also, make sure to check the numbers on your current wheels for hardness and width for a good fit.
