Hildebrand & Wolfmüller

From Wikipedia, the free encyclopedia

In 1894, the Hildebrand & Wolfmüller was the first motorcycle that was available for purchase. This is in contrast to Gottlieb Daimler’s Reitwagen of 1885, which actually only served as an experimental application for the engine and was not manufactured in a series let alone developed further. Heinrich and Wilhelm Hidebrand had previously experimented with steam power, before joining with Alois Wolfmüller to produce their revolutionary internal combustion Motorad in Munich.^[1]

Technical Specifications of the Hildebrand & Wolfmüller of 1894: Patent of 20 January 1894, No. 78553: 2 Cylinder four-stroke engine, 1488cc, Bore and stroke: 90 x 117mm, Ax. 2.5HP at 240rpm. Weight ax. 60kg and a maximum speed of ax. 40km/h. The Motorbike featured a water-cooled engine and a hollow tube frame, both of which were well advanced for the time. The rear wheel was driven by pistons similar to those in a locomotive, and used heavy rubber bands (one visible in the photograph, horizontal and running low down towards the rear wheel) to provide a return impulse rather than rotational inertia (as of a flywheel).

Only a few hundred examples of this model were ever built. Apart from the high purchase price, technical problems such as the absence of a clutch prevented the motorbike from becoming a commercial success. The venture ended as a financial failure for both the Wolfmüllers and Hildebrand, their financial backer. Their factory closed in 1919.^[2] Examples exist today in the Deutsches Zweirad-Museum, Germany, the Science Museum in London, the Henry Ford Museum in Detroit, Michigan, the Wells Auto Museum in Wells Maine and the Museum Lalu Lintas Surabaya, Indonesia.
