On some mopeds the wheel bearing are the old cup and cone type used on bicycles. They have a tendency to go bad expecially on the drive sprocket side of rear wheels. I have access to tons of wheels where this has happened and was looking for a way to rebuild them. That seems to be the Achilles heel of a moped when striving for faster speeds. I was wondering if anyone has modified and used sealed bearings like used on motorcycles. If so, how did you do it and do you have any pictures of your modifications? I'm planning on doing this and would like some tips of what to look out for when doing this modification.
