My boss has a couple of older bikes he's wanting to get rid of and wants me to help sell them.
I have no idea about the years of these bikes and didn't see any markings on the frame from where I could see.
The first is a Schwinn Sprint. There is a sticker on the rear near the gears that says "schw app GIANT".
The second is a Nishiki Century (or vice versus.. I don't know).
