Reminiscent of a well-known English design, a flat twin engine specially designed for motor cycle or cvcle car work has been produced by the Bayeerisch Motoren Werke, near Munich. This firm has a very fine factory, erected during the war for the construction of aeroplane engines.
Since the Armistice the works have been converted, and among the new products is the llat twin air-cooled engine
shown in the accompanying illustrations. Hie design us. wonderfully neat, , and the engine is most up to date in every respect. The two cylinders, which have enclosed side by side valves, are mounted on ail aluminium base chamber which forms an oil reservoir. The crankshaft is mounted in ball bearings, the connecting rods are tubular, and aluminium pistons are used. The flywheel is external, and the magneto, a high-tension Bosch, is placed on the top of the crank case. It is claimed that the engine will run under load at 3,400 revolutions, and will turn over at 5.000 revolutions without load. It is the intention of the B.M.W Co. to produce this engine in quantities for the trade.
Conditions in Germany.
Very few motor cyclists are seen on German streets and roads. Indeed, during a very extensive tour through that country not a single touring motor cyclist was observed, but a certain number of motor-assisted cyclists were met in the leading cities. The reason for this neglect of the motor cycle, is the high cost not only_ of machines, but of fuel, tyres, and repairs.
Until a very short time ago motoring could only be indulged in with a special permit. It is now free, but petrol is very expensive, the legal price being 4 marks 50 per litre, but it is practically impossible to obtain it at this price. The use of a car has gone beyond the means of any but a few nouvraux riches, and it is because of this that the motor cyele industry is believed to offer possibilities. It will be several years, however, before even this form of economical motoring becomes really common.
