Grivel was a French automobile manufacturer based in Neuilly-sur-Seine. Production started in 1896 and ended in 1897.
In 1896 a Grivel Tricycle-Tandem took part in the Paris-Marseille race, but suffered an accident. The vehicle was powered by an air-cooled, horizontal two-cylinder petrol engine that produced 2 HP.[1]
In 1897 a Quadricycle with rear engine was available. It featured a tubular frame and the same 2 HP engine as in the Tricycle-Tandem. The driving power was transmitted directly to the rear axle by a gearbox. The total weight was 180 kg.
