This electrically assisted bike integrates a fuel cell of small size, operating on hydrogen and connected to a tank, placed in the frame of the bike. With a power of 200 W, the fuel cell is coupled with a small lithium battery that powers the electric assistance of the bike, offering a range of 100 km. Neogy® designed the “core energy” system: the BMS / Battery Pack design, and the electronic board allowing the hybridization of the system elements.
