The GEKO company designs, integrates, manufactures, and markets electric powertrains for high-performance or demanding applications in very small and small series. The ecological transition associated with environmental issues affects all sectors, including leisure or competitive activities, using technologies that generate air and noise pollution. GEKO's ambition is to use its experience in the creation of technologically advanced electric propulsion chains to offer turnkey solutions to contribute to the decarbonisation of mobility. With its skills, GEKO can take charge of the marketing of electric powertrains using battery-type energy storage technologies (lithium, LTO, Ultra capacitors, etc.) on specific applications. The medium-term strategy is to apply its knowledge of energy integration and management while extending its know-how to the use of hydrogen storage solutions with fuel cells.
