[1] The success of other manufacturers' three-wheeled commercial vehicles during the Great Depression made BMW Munich develop its own tricycle lorry in 1931.

Windshield, wiper, cab, doors, electric turn indicators, spare wheel, and car jack were available as factory options and cost extra.

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,[3] 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.

[6] The engine was mated with a three-speed gearbox with reverse gear and a propeller shaft to the rear wheel.

[7] The rear wheel had a single control arm and a leaf spring, aligned longitudinally to the prop shaft.
