Company History
Simson’s mopeds and light motorcycles mobilized East Germany for decades. The Schwalbe scooter and S-series step-throughs were engineered for everyday survival—oil-bath chains, robust electrics, generous ground clearance, and engines that forgave indifferent fuel. Parts were available in village shops; owners learned maintenance as a civic skill. After reunification, Simson machines became cult classics: simple, charming, and legal oddities in some regions thanks to transitional rules. Clubs keep them alive with reproduction spares and shared know-how. Historically, Simson symbolizes transport as infrastructure under constraint: make it fixable, make it last, and let it be the tool that carries a nation to work, to school, and to weekend lakes on the same faithful cylinder.
