Key Highlights: 

• U.S. market debut: BMZ will introduce its POWER2RIDE RB-900 battery at Micromobility America, November 11–12, 2026, in San Francisco, bringing its high-capacity battery technology to American e-bike manufacturers.
• High energy density: With 940 Wh of capacity, a weight of just 3.8 kg (8.4 lbs.) and an energy density of 247 Wh/kg, the RB-900 combines high energy storage capacity with a lightweight, compact design.
• Flexible integration across e-bike platforms: Modular architecture, compatibility with leading drive systems and multiple mounting configurations give OEMs greater flexibility to develop electric mountain, commuter, trekking and cargo bikes.
• Designed for safety, serviceability and sustainability: Automotive-grade components, IP67 protection and a repairable, modular design support durability and product lifecycle management.

SAN FRANCISCO, Nov. 9, 2026 — BMZ Battery Solutions Group, an international manufacturer of high-performance battery systems, will introduce its POWER2RIDE RB-900 e-bike battery to the U.S. market at Micromobility America, November 11–12, 2026, in San Francisco. Designed for electric bicycle manufacturers seeking greater battery capacity without sacrificing weight, aesthetics or integration flexibility, the RB-900 combines 940 watt-hours (Wh) of energy capacity with a weight of 3.8 kilograms (8.4 pounds) and an energy density of 247 Wh/kg.

As electric bicycle manufacturers work to deliver greater range, accommodate multiple drive systems and differentiate their products through design, battery technology has become an increasingly important consideration in product development. The RB-900 addresses these competing requirements through a modular battery platform that supports multiple bicycle categories, frame configurations and OEM customization needs.

"E-bike manufacturers face growing pressure to deliver greater range and performance while maintaining the flexibility to create distinctive products," said Łukasz Kądziołka, Sales and Business Development Director at BMZ Poland. "With an industry-best energy density of 247 Wh/kg, the RB-900 is the most efficient battery on the market today, combined with a lightweight, modular design. We're bringing this technology to the American market to give OEMs greater flexibility to develop their next generation of e-bikes."

Greater Battery Capacity Without Compromising Bicycle Design

The RB-900 combines state-of-the-art lithium-ion battery cells with a slim, oval cross-section designed to accommodate demanding frame geometries, including smaller size-S frames. Its compact form factor gives bicycle manufacturers greater flexibility to integrate substantial battery capacity while maintaining the aesthetics and handling characteristics of their products. With 940 Wh of capacity and an energy density of 247 Wh/kg, the battery supports extended riding range (at least 17% greater range than competing high-capacity batteries in the under-4 kg category) without the proportional weight increases associated with larger, heavier battery systems.

The battery supports a broad range of applications, including electric mountain bikes (eMTB), trekking bikes (eTrekking), city and commuter bikes (eCity/eCommuter), SUV-class e-bikes and electric cargo bikes (eCargo). For cargo applications requiring additional energy storage, its dual-battery configuration provides nearly 2 kWh of combined capacity.

Modular Architecture Gives OEMs Greater Integration Flexibility

The RB-900 is engineered to simplify battery integration across different bicycle platforms. Its modular architecture allows manufacturers to adopt the battery as a ready-to-use production solution or customize it for specific original equipment manufacturer (OEM) and original design manufacturer (ODM) requirements.

Designed to work with leading e-bike drive systems, including Shimano, Panasonic, Motinova and Bafang, the platform gives manufacturers flexibility in selecting components and developing different product models.

Its integration features include:

• Multiple mounting configurations: Top, bottom and slide-in installation options for integration within the bicycle frame's downtube.
• Frame material compatibility: Support for different frame construction materials and installation configurations.
• Drive-system compatibility: Integration capabilities for multiple leading motor and drive-system platforms.
• Charging flexibility: An optional USB-C charging/power bank feature.
• Expandable energy capacity: Dual-battery configurations for cargo bikes and other high-demand applications.

These capabilities allow OEMs to evaluate a common battery platform across multiple product lines rather than developing separate battery architectures for every bicycle category.

Automotive-Grade Components Support Safety, Durability and Serviceability

Beyond performance and integration flexibility, the RB-900 incorporates advanced engineering and design features intended to support reliability, durability and sustainability, including:

• Automotive-grade components: Engineered to support reliability and durability in demanding riding environments.
• Water and dust resistance: IP67 protection rating for resistance to dust and water ingress.
• Real-world performance testing: Tested in demanding riding conditions, including mountain biking applications.
• Repairability and recyclability: Modular architecture designed to facilitate product servicing and end-of-life battery management.
• Regulatory readiness: Developed with evolving European and U.S. regulatory requirements in mind, including requirements expected to take effect after 2027.

"Battery performance is only one part of what manufacturers need from a technology partner," Kądziołka added. "Compatibility, reliability, serviceability and regulatory readiness are increasingly important throughout the product lifecycle. Our approach with the RB-900 is to combine these priorities in a flexible platform that manufacturers can adapt to their individual needs."

Building on BMZ's Global Experience in E-bike Battery Technology

The RB-900 builds on BMZ's extensive experience developing battery systems for electric bicycle manufacturers worldwide, including:

• Global manufacturing and service network: Manufacturing, sales and service operations across Europe, the Americas and Asia support bicycle manufacturers operating in multiple markets.
• Proven global deployment: More than one million bicycles equipped with batteries developed by BMZ engineers in Gliwice, Poland, are operating across Europe, North America and South America.
• Specialized engineering expertise: BMZ's Polish engineering team serves as the Group's competence center for premium battery solutions and custom battery development for bicycle manufacturers.
• Established industry partnerships: BMZ batteries are used by leading e-bike brands and professional mountain biking teams, including the Rotwild Schwalbe Gravity Team.
• Applications beyond e-bikes: The RB-900's modular design and automotive-grade components offer potential applications in light electric motorcycles, industrial equipment, autonomous guided vehicles (AGVs), autonomous mobile robots (AMRs) and personal watercraft, subject to application-specific engineering and validation.
