Is it possible to make a 2 seater motor bike ride? I have a strong bike never having problems with the bike (frame, wheels) itself. Could it handel 300 pounds of passanger and rider weight? I was thinking of getting a longer bigger seat 26 inch or some how make a seat out of a cargo thing above the back tire behind the seat. I'm not thinking of an ideas with the passanger on the side of the bike I don't like that idea.
