I think the bike is prolly a single speed (BMX freewheel), not a fixie, given the front and rear brakes. Them big platform pedals work good with sneakers. The crank is Stronglight, not Campy, so maybe the builder found the frame and built around it.

I do kinda like the build and certainly understand it. Quirky, not bad, plus they didn't hack off the rear mech hanger, so it's not like the build can't be redone back to original.
