Ive been building up a folding bike.

Is a Hercules compact.
I was given it.
Thought it was a horible Bianca clone.

I widened the rear end with a scaffold pole against the seat tube...for a 7 speed 406 20" wheel
The frame is badly made. The chainstays are hardly welded to the BB shell. Theres big gusset plates there. The BB seems ofset to one side.
The BB takes normal cups.
I fitted a Solida alloy crank the same as my 20 has. Was the first out of the box.
Havent put brakes or cables on it.
Going to see if I can get the weight low enough so I can carry it on the bus.
See if I can get a bag for it.
