Łukasz Kądziołka, director of sales & business development at BMZ Poland explains why the RB-900 is getting so much buzz—and why he thinks it might be the best thing to happen to e-bikes in years. “It isn’t just another battery—it’s a glimpse into the future of e-mobility. Designed as a global battery platform, it serves not only as a high-performance, off-the-shelf product for everyday riders, but also as a robust OEM and ODM solution for bike manufacturers worldwide.”
“This is important news because most batteries force riders to choose between light and agile, or heavy and long-range,” Kądziołka adds. “The RB-900 breaks this compromise. It lets you enjoy long rides without weighing your bike down. Its compact and slim design means it doesn’t just power your bike—it complements and enhances it, making modern e-bike frames look and feel sleeker than ever.”

Benefits for manufacturers and riders
“The RB-900 is a game changer for manufacturers,” says Kądziołka. “It adapts seamlessly to various frame sizes—including S-size bikes—thanks to its short, innovative construction and flexible assembly options. It is compatible with multiple e-drive systems (including Shimano, Panasonic, Motinova, Intradrive, Oli eBike Systems, Bafang, BMZ RS/GT, and Sachs RS). In addition, its adaptability and modular design—along with compliance with the most stringent European safety regulations and the upcoming 2027 requirements (single cell replacement) —guarantee business security and future readiness for brands that adopt it.”
For riders, the benefits are also clear: longer, worry-free adventures, quick and easy charging (via both 8-pin and USB-C options), superior resistance to water and dust (IP67), and access to BMZ’s global aftersales and service network. “It’s a battery designed not just for performance, but for real-world use—no matter where you ride,” Kądziołka adds.
Lightweight, powerful, and built for all-day adventures
“The RB-900 is designed to make range anxiety a thing of the past,” emphasises Kądziołka. “Weighing just 3.8kg yet packing up to 860Wh of energy, this battery lets you go further. You can ride up to 150 kilometers on a single charge, depending on your bike and riding style. So you don’t have to choose between a lightweight bike and long range ever again.”
“Need a superlight option?” continues Kądziołka. “It’s also available with 650Wh and a weight under 3kg. And if you need a super power e-cargo option above 1000Wh, you can use the multi-battery, high voltage (48V) option.”

Cutting-edge design for every rider
“Forget bulky, awkward batteries—the RB-900’s unique and slim, and oval cross-section gives your bike a modern, streamlined look,” says Kądziołka. But it’s not just about aesthetics: the compact design fits S-size frames and is compatible with all types of bikes—eMTB, eSUV, eTrekking, city commuters, and even eCargo.
Installation is simple thanks to a new user-friendly assembly set, with options for top, down, or in-tube sliding inserts. It integrates smoothly with all frame materials, including carbon.
Safety, durability, recyclability and serviceability
“Wherever you ride or store your e-bike, the RB-900 keeps you protected,” notes Kądziołka. “The battery is IP67-rated for the highest resistance to water and dust. It also complies with the latest European regulations (2023/1542), including single cell replacement, making it future-proof for riders and manufacturers alike. Its modular construction ensures easy repair and recycling at end-of-life. It is also up-to-date certified, far exceeding just EN50604-1 compliance, and uses automotive-grade components. Plus, BMZ provides global aftersales service for the battery.”
The RB-900 doesn’t just store energy—it brings your e-bike into the future”
Smart features and fast charging
“The RB-900 doesn’t just store energy—it brings your e-bike into the future,” explains Kądziołka. Beyond fast charging, it also supports charging and discharging through an optional USB-C connector (making it a really powerful power bank). And it uses the latest battery cell technology.
“If you love e-biking, riding as a professional eMTB rider—or you’re just thinking about getting started for everyday commuting—this battery is a genuine game changer,” continues Kądziołka. “It’s not just about longer adventures or worry-free commutes; it’s about having the best performing, safest, and smartest battery powering your ride.”
Kądziołka concludes: “Ready to experience the difference? The RB-900 isn’t just powering e-bikes—it’s powering a whole new way to ride. Will you be part of the revolution?”
