I agree with @
Raiderbob,... A Worksman bicycle has a strong steel frame, and the welds will be very strong. Heavy duty tires, inner tubes, and high spoke count rims will be a plus, but an aluminum frame designed for a lighter weight rider isn't something I'd recommend.
Maybe someone else can assist, or you could always ask in the
Clydesdales/Athenas (200+ lb / 91+ kg) section of the forums. I'm a member of that section as well!
