Here are pictures of my 1955 Rudge, powered by a 23cc tanaka 2stroke engine. The power is directed via a friction drive roller which rubs on the front tire. This assist motor was marketed under a few different names. The human power is routed through a three speed hub with a triple drive sprocket thus offering nine different gear combinations. The front hub has a integral 6volt low speed alternator, for lighting purposes, known by the trade name of Dynohub. The rider is supported by a leather Brooks saddle.
