A complete motor bicycle which arrived late at the Stanley Show last week was the Eole—a 4 h.p. machine sprung fore and aft—sold by the Mills Motor Co., 29a, Charing Cross Road, W.C. The back stays are hinged behind the bottom bracket, while the back stay tube works against a concealed spiral spring. The above are the two points which specially call for attention, the rest of the machine following standard practice. The engine is fixed vertically in the frame, and has a mechanically-operated inlet valve. The ignition is by accumulator and coil, and the carburetter is a Longuemare. The machine is of Belgian manufacture.
