The motorcycle featured a [[water cooling|water-cooled]] engine (the coolant tank/radiator of which is prominent over and around the rear wheel) mounted in a purpose-designed tubular frame. The rear wheel was directly driven from the [[connecting rod]]s (a similar arrangement to that of steam locomotives). There was no [[flywheel]] other than the rear wheel, and it needed heavy rubber bands to provide the return impulse.[[Image:1894 Hildebrand Wolfmuller diagram.png|thumb|left|Diagram of 1894 Hildebrand & Wolfmüller.]] | The motorcycle featured a [[water cooling|water-cooled]] engine (the coolant tank/radiator of which is prominent over and around the rear wheel) mounted in a purpose-designed tubular frame.
