Bohemia
The Böhmerland , delivered to Czech customers as Čechie , is considered the longest production motorcycle in the world. It was produced from 1925 to 1939 by the mechanic Albin Hugo Liebisch (born July 26, 1888 in Rumburg , Auplatz 26; † November 9, 1965 in Passau ) in Schönlinde in what was then Czechoslovakia . The engine, frame and the peculiar fork - it's a pushed short swing arm - were designed by Liebisch.
The Böhmerland was characterized above all by its three-seater bench and the placement of the engine in front of the driver, which gave it its enormous length. The two cigar-shaped tanks were attached to the rear portion of the frame, leaving so clear view of the valve rocker arms of the OHV - a single cylinder that were placed between the driver's knees. Later there were also models with additional tanks of the usual design on the top tube, which obscured the view of the valve rocker arms. In addition to gasoline when warm, diesel and heating oil should also be possible as fuel.
A total of approx. 775 copies were built, including special models, e.g. B. a shorter version for only two people and a longer version for four people. The latter was intended for the military and had two transmissions, the first of which was shifted by the driver and the second by one of the passengers. The machine thus had nine gears. A racing version was also made that was supposed to be 160 km / h. A sidecar with a spare wheel was also available. The machines were assembled in the assembly plant by 20 workers from parts that were manufactured by regional suppliers. A total of around 300 people were involved in the production.
There are still around 75 pieces in the hands of enthusiasts and in museums, around 40 of which are ready to drive. The price of a faithfully restored copy is estimated (2002) at around 30,000 euros.
The prototype of a four-seater Böhmerland is exhibited in the PS store in Einbeck, Lower Saxony.
