The Winkie was a rear chain driven children's tricycle manufactured in England by Raleigh Bicycles between 1950 and 1970. [1] [2] [3] Raleigh marketed the tricycle to children by having them automatically join an owners club called The Circle of Silver Knights which taught traffic safety while also acting as a way to sell tricycles. The construction is welded steel tube with steel wheels and a single speed driven by a chain attached to a solid rear axle. [4]
