I am watching the British Road Show and was surprised that on gent had 20 inch bicycle for value check.
He was probably late fifties and had a Raleigh Chopper bicycle ; I did not know that Raleigh ever made their version of the Schwinn Sting Ray.. It still had the original redline tire in good shape, the tread was different from any I ever saw on a U.S. bike.
He paid ( £500) 567 dollars for it, as an adult, and found it is now worth (£700) 794 dollars.
