Every JD Razor 2000 has two wheels, the front wheel which is located directly underneath the handlebar, and the back wheel which is located underneath the wheelie bar. The JD Razor 2000 guide provides instructions for the replacement of the back wheel.
Facing the wheelie bar as shown, place your left thumb on the bolt located on the left side of the back wheel and place the Allen wrench into the screw on the right side of the back wheel.
Using the wrench, slowly unscrew the bolt while applying constant pressure from the left side.
Remove the bolt from the right side and the bearing from the left.
Turn the JD Razor 2000 on its side as shown. Slowly remove the back wheel by pulling it out at a perpendicular angle to the scooter base.
