You are correct. Cyclist=bicycle and Biker=motorcycle
Appreciate the confirmation. Thanks much. :)
I should also add that the major print publications that deal with bicycling are named “Cycling”, “Cycling Plus”, “Professional Cycling”, “Cycling Plus”, etc.
Whereas ones dealing with motorcycling are named a bit differently. Including television programs. “Easy Rider”, “American Biker”, “Iron Horse”, “Custom Chopper”, etc.
Of course, Mopeds are a whole different breed. :)
