MOST of the bikes are Schwinn...i have many Hiawatha and Hawthorns...some pre "schwinn" Schwinn built bikes...some are heavy-weights, most are mid-weight balloons...I have some 3-speed...some 10-speed...BFG, Goodyear, Rollfast (sp)...i'm overwhelmed with bikes and bike parts...i checked out "theCABE" and i'm thinking about buying some books, but these parts are really only worth what someone will pay, no matter what a book tells you...as I was unloading the 2nd truckload, I had doubts about what I REALLY got myself into [i dropped ALOT of cash on this deal, thinking it would be a good start to a buisness (thinking I could make the money back in the PARTS I have and the Bikes would provide the financial coushion)]...
