Hi my names Gerald I recently started my first motorized bicycle build posted /2 is sprockets and chain I can't find a #25h chain anywhere I'm thinking about buying new sprockets #35 but I don't really know about gearing and sprocket size and Tooth count .I have a 20t front sprocket and a 44t rear sprocket what does this mean? How fast will it go? How can I gear it to get 35- 45 mph and what kind of mpg expect? I am thinking about getting and upgrading a 80CC 2stroke Skyhawk are then any good?
