The company used the Bayard trade name (after the legendary horse of Renaud de Montauban) and manufactured the Bergmann–Bayard pistol and the Bayard 1908 pistol.
The company is also notable for having produced a small pistol with a tip-up barrel ("basculant") to facilitate loading.
[2] In 1900, Henri Pieper introduced a hybrid vehicle with an electric motor/generator, batteries, and a small gasoline engine.
It used the electric motor to charge its batteries at cruise speed and used both motors to accelerate or climb a hill.
Auto-Mixte, also of Belgium, built vehicles from 1906 to 1912 under the Pieper patents.
