B'Twin 36V electric bike battery

B'Twin is a prominent cycling brand that originated in France as a dedicated label for bicycle products under the Decathlon Group. Since its inception in 1976 (originally as Decathlon Cycle), the brand has become synonymous with accessible and high-performance cycling equipment, from entry-level mountain bikes to specialized components.

This specific 36V battery is designed for their range of electric-assist bicycles. While the brand carries French heritage and is engineered in Lille, France, the manufacturing of electronic components and battery cells is primarily outsourced to specialized facilities in China and other Asian electronics hubs to leverage large-scale lithium propulsion technology. Decathlon maintains strict control over the design and testing phases to ensure safety and compatibility with their global fleet.
