Re: Heavy duty bike frame?
What engine will go in the bike? The Worksman frame in stock form doesn't have a lot of room for an engine. Even a China girl is a tight squeeze unless you modify the frame. That's what I had to do to fit a 98cc Sachs engine in mine.
I also have a 50 Schwinn straightbar frame (Panther)which has a lot more room without modifying the frame.
So it makes a difference iwhat engine you intend to use and whether or not you are willing to alter the frame.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
