I got this classic Fuji folder for $50 in October for my son so we could ride together. The crank was loose so I serviced the BB, wheels, and brakes today. It's 15 speed (3 x 5) Shimano group and freewheel.
It doesn't have much wear other than some rust on the brake lever adjustment screws. I replaced the original seat and folding platform pedals. The rear flatted immediately (tube failure at stem).
