Triomobil was a car brand that was built between 1903 and 1909 by the mechanical workshop Otto Spiess in Berlin-Spandau . The workshop existed since 1894.
The Triomobil was a tricycle with two seats. Above the single front wheel sat an air - cooled single - cylinder four - stroke engine with an open flywheel, which developed 4.5 hp (3.3 kW) of power and drove the front wheel over a chain. This "subframe" was steered with a long pole.
In 1909, the company had to give up spit.
