Classic Motorcycle part #7
The most popular model was the so called Zehnderli ( ? little Zehnder ?) which was equipped with a 110 or 148 two stroke engine. This is a German Cockerell auxiliary engine that was made under licence. A striking feature of the little Zehnder is the place of the petrol tank: not as one would expect between the frame tubes, but on top of the engine, under the frame tubes. The empty space between the tubes can be used for a leather tool box.
The compact two stroke engine has a Bosch magneto. It has a two speed gearbox and both primary and secondary transmission is by belt. The compact machine weighs 50 kilograms and the low position of the petrol tank gives a very low centre of gravity and good road holding. Initially this model was used as a touring mount; its reputation was made in 1925 when in the great Swiss reliability trial that involved very strenuous mountain courses all seven started Zehnderlis won gold medals.
