Check A Bike Wheel’s Rear Hub

Introduction

The rear hub must hold the wheel firmly to the bike and also allow the wheel to turn.

Step 1

Is the rear hub loose enough?

Lift the back end of the bike so the rear wheel is off the ground. Give the wheel a spin. The easiest way to do this is by gently pressing a pedal. It must turn smoothly without clicks or catches. If the bike has a freewheel that will make an even noise but the rear hub must be smooth. If there’s a problem with the brake open it to check the rear hub. Mudguards rubbing may be another source of distracting problems.

Step 2

Is the rear hub tight enough

Grab the rim and pull it sideways. There must be no discernible movement at the rearhub. If the wheel moves from side to side on the axle the bearing is too loose. This test also checks if the wheel axle is clamped tightly in the frame.
