Stark Future signs new strategic partnership with EVE Energy
B2B News | Stark Future has taken a major step toward reshaping high-performance electric motorcycling by announcing a strategic partnership with global battery giant EVE Energy. The collaboration will bring Stark’s newly developed 26120 cylindrical cell, a battery format engineered specifically for motorcycles, into mass production.
While most electric motorcycles still rely on automotive-derived 21700 cells, Stark’s new 26120 format is designed from the ground up around the structural and thermal demands of two-wheel performance. By exploiting the natural width of a motorcycle chassis, the larger-diameter cell promises higher energy density, improved cooling, lower weight and faster charging.
A battery built for bikes, not cars
According to Stark Future CEO and founder Anton Wass, the motorcycle industry can no longer be limited by automotive battery conventions.
“To build the best motorcycles in the world, we shouldn’t compromise by using technology developed for cars,” Wass explained. “This new architecture increases capacity, reduces weight and dramatically improves charging time. It will redefine what’s possible in premium electric two-wheel performance.”
Early prototype cells, already under test at Stark’s R&D headquarters outside Barcelona, are showing record-breaking energy density of 330 Wh/kg while maintaining 10-minute ultra-fast charging, a combination that could set a new benchmark not only for motorcycles, but for the wider EV sector.
Aluminum enclosure for superior cooling and weight savings
Unlike the conventional steel-canned cells found in most EVs, the new 26120 cell uses an aluminum enclosure to enhance thermal conductivity and reduce mass. Improved cooling efficiency is especially critical for high-output motorcycles, where sustained power delivery can quickly expose weaknesses in battery design.
EVE Energy’s leadership sees enormous potential in the new format.
“The 26120 cell has incredible potential,” said Dr. Liu, Founder and President of EVE Energy. “It may become one of the highest-energy-density cylindrical cells in the world today. Our collaboration with Stark shows how innovation can redefine lightweight EV performance.”
Dr. Zoe Lu, R&D Director at EVE, echoed that view, emphasizing the cell’s capability to push technical boundaries and reshape expectations for motorcycle electrification.
Industrial production begins in 2026
With the partnership formalized, EVE Energy will begin preparing for industrial-scale production of the 26120 format in 2026. Stark Future plans to integrate the technology into its upcoming on-road platforms, signaling a clear move beyond the off-road segment where the company’s flagship VARG motocrosser has already shaken the industry.
Wass believes this project sends a message to battery manufacturers worldwide:
“The motorcycle industry is ready to transform. We’re not waiting for innovation to trickle down from cars, we’re leading the way.”
A new era for high-performance electric motorcycles
Stark Future has rapidly become one of the most influential players in electric powersports. Founded in 2020, the company has already released the VARG, the most powerful motocross bike ever made, and continues to pursue a vision of outperforming combustion while accelerating the industry’s shift to sustainable technology.
With the introduction of the 26120 cell and a manufacturing alliance with one of the world’s top cylindrical battery producers, Stark Future is positioning itself at the forefront of the next generation of electric motorcycle performance.
