Lot 184: c.1952 Steyr Junior 18cc (Lohmann) Cyclemotor

One of the most technically interesting machines from the Ehn museum is this diminutive cyclemotor engine, mounted on what is described as a pre-war, Austrian army Steyr ‘waffenrad’ bicycle. Museum-catalogued as a Steyr ‘Junior’, this is a re-titled German Lohmann diesel engine. The Lohmann has more of a resemblance to a high-speed model aircraft engine than to a cyclemotor, both in its diminutive 18 cc capacity and compression-ignition operation. With no ignition system the throttle operates a contra-piston varying the compression and, thus, the power, up to 0.8 bhp at 5000 rpm using ‘green’ fuel. A fund of knowledge is available at club level enabling the new owner to ‘make it go’ joining the very select band of Lohmann owners.
