Understood... On some of the older bicycles the frame is just longer. For example I have an old Ted WIlliams Step Through. Sold by Sears long ago the frame was actually made my Austro-Daimler in Hungary. It is a long frame with plenty of room for fitting a bicycle rack and fenders. There is allot of room between the rear tire and the seat tube. I saved the frame and added parts box components to it for a nice ride. It takes a 62 inch chain to fit the 34T freewheel cog to 51T large crank ring. Its a very fast sleeper bike, and when my boys come over its one of thier favourite rides.
