The BMW F 76 was a small tricycle delivery van made by BMW. It was built from 1932 to 1933 in BMW's Eisenach plant. In 1933, the BMW F 79 version with a larger engine was put into production. History Development The BMW 3/15's van version did not sell very well; only 435 vehicles were sold from May 1929 to February 1932. The success of other manufacturers' three-wheeled commercial vehicles during the Great Depression made BMW Munich develop its own tricycle lorry in 1931. It had a two person bench seat and a single-cylinder motorcycle engine. A one-seat variant had been tested as well as a passenger car, but both were not put into production. Marketing In autumn 1932, the F 76'''s production commenced in the BMW Eisenach factory. It had a 200 cc engine, and therefore, could be driven legally without a driving licence. It was priced at RM 1350. In January 1933, the F 79 version with a 400 cc engine was introduced; it cost RM 1500. A horn and a speedometer were standard. Windshield, wiper, cab, doors, electric turn indicators, spare wheel, and car jack were available as factory options and cost extra. Various modified versions of the freight compartment were also offered from the factory. After a total production of just 600 units (250 F 76 and 350 F 79''), the manufacture was in 1934 ceased due to low demand. Technology Drive construction The engines used were single-cylinder four-stroke OHV engines that were derived from the motorcycle engines of the BMW R 2 and BMW R 4. There were at least two variants for engine cooling: a simple solution with a V-belt-driven, four-bladed fan in front of the cylinder, which was only seen on the test vehicles, and a more elaborate design with impeller on the front crankshaft stub and air baffles for cooling air, which was also described in the manuals and spare parts lists. The engine was mated with a three-speed gearbox with reverse gear and a propeller shaft to the rear wheel. Chassis The tricycle had only one single driven rear wheel and two steerable front wheels. The rigid front axle was suspended by two longitudinally mounted leaf springs. The rear wheel had a single control arm and a leaf spring, aligned longitudinally to the prop shaft. BMW used this groundbreaking design principle again for their 1980's BMW R 80 G/S motorcycles. The
