A Brief History of the Marque
Manufactured by Eisenwerk Becker & Co. of Leipzig, 1923-1924
Based on a design by Ing. J. Schneeweiß, the company built three models powered by parallel twins of 514, 642 and 804cc.
MOTAG - The "two-wheeler car"
An example of the use of light metal casting is shown in the two-wheeled car shown in FIG. 503. The front part of the wheel body consists of a helmet-like molded half-hollow body, which forms the front fender, the front wheel hub summarizes, cushioning device and also includes the steering device. This part is cast in one piece. The main frame is composed of a strong, cast in a right and a left half lower part. These pieces are flanged together on a ground surface with a few bolts. The lateral lattice girders form the bridge to the casting of the rear wheel body, with which they are also flanged. It consists of the entire frame so six castings, which are connected by bolts. In the front part of the hollow body is the gas tank, opposite to the direction of travel is the completed by a lid tool box. Immediately below the seat is the radiator of the engine, if a water-cooled engine is used.
Flanged directly to the main frame is the cast in two lateral halves rear fender, he takes on the rear hub, also closable in its upper cavity by means of a lid, a spacious container. The lid is upholstered on its lower side and turns upside down as a pillion seat. As the designer emphasizes, he has moved to this peculiar frame training to save on working time. It is questionable whether this framework will be particularly cheap, despite the fact that it saves on wages in the frame factory. The break-free and crack-free production of the individual, after all, considerably large castings is likely to be difficult, but if this is possible even with a very low percentage committee, then only a probation in practice should speak the right word. After all, the idea is in itself at least original and should show ways that should not be ignored for the construction of heavy machinery. The heavy-weight machine, as mentioned earlier, just needs a special careful design, not too weak and not too strong frame sizing. It is most blatantly expressed in this embodiment that the heavyweight machine is closer to the single-track car than the normal and evolutionary normal motorcycle designs. This refers to the frame in a very preferred extent.
