How do you align the rear sprocket????
I am really getting into these motorized bicycles and have been reading the posts and studying the information here and everything seems straightforward except one thing.
When you install the rear sprocket onto your existing wheel, I notice that it has the sprocket and another plate and some gasket-like material around the spokes. This whole thing bolts together, but how do you get the sprocket centered on the axle so it isn't out of round??
