Hello Bike one.I own a Mezzo upgraded to 27 speed dual drive, and a few other items swoped to save weight.It also has improvised low profile handle bars and shimano STI road race levers/brakes. Occasionally has MZS cude clippless detachable pedals on. Definately a keeper!
Bike two is simular sort of thing done to a Downtube NS8.
Bike three is a upgraded mission space genie with 21 speed dual drive for off road work
