On a recent ride I noticed a clicking sound coming from my front wheel. Suspecting a bearing, I took the wheel off and found it to have considerable drag. It felt like it was grinding inside the hub. So I decided to have a look and rebuild my wheel bearings.
For those of you that have never done this, I have attached a video that you will find very helpful. With the right tools, rebuilding and repairing wheel bearings is a snap. In the end, having a smooth rolling wheel is very satisfying, safer and adds to the efficiency and pleasure of your e-bike ride.
I recommend inspecting your wheels regularly and rebuilding them any time you hear or feel a change.
