Most balloon tire bombers (Schwinn Breeze, and all those), use an
Astabula crank, which is a very large, very heavy single piece of cast
iron.  They also use coaster brakes.  The mountain bikes have a bottom
bracket for ten-speed type cranks, braze-ons for cantilever brakes, and
so on.  The mountain bike is actually descended from ten-speeds by way
of the cyclo-cross bike (cross country racing on knobby sew-up tires).

Of course, nobody is stopping you from putting knobbies on your bomber
and climbing mountains just for fun.
