This is a 1975 bike verified by both the frame number and the sturmey archer hub. It is in superb condition with very little corrosion or rust and absolutely original. An unusual combined three speed gear and dynamo hub that works perfectly. The hub powers the original lights which are near perfect condition and work a treat. The bike is a pleasure to own as a collectible however it also rides very nicely with everything working as it should. An unusual indeed rare find to get one in such good original condition.
