If 48cc is usually the legal limit for motorized bicycles on the street then please explain to me why the larger 69cc (80cc) seems to be the more popular engine size used. Maybe since there is no engine size stamp to reveal the size then do you all just lie to cops when they stop you and say its a 48cc? Or are most of them used in very rural situations instead of the cop infested cities? I am really curious to understand this. Keep in mind I am in Ecuador and cant see the situation in civilized countries.
