Berlin (November 02, 2023). After five years, the Brose Drive S Mag is still impressing bike experts all over the world. As the centerpiece of SRAM's new Eagle Powertrain, the proven e-bike engine impressively demonstrates why it remains the first choice for the demanding bicycle industry. With the Eagle Powertrain, the S Mag is currently installed in models of the four trendy e-mountain bike manufacturers Propain, Transi?tion, Nukeproof and Gasgas.

SRAM, the renowned U.S. manufacturer of bicycle components, had been looking for the ideal drive for its innovative e-bike system with automatic shifting function at the start of product development and found the perfect solution in the Brose S Mag.

Simon Kolmstetter, product manager for e-bike systems at SRAM, tells "When it came to the drive, we stuck to proven hardware. Our test team in Schweinfurt has tested a wide variety of systems. For us, it simply turned out that the Brose motor is the best compromise between noise, power and volume."

Brose revolutionized the e-bike market in 2018 with the S Mag's magnesium housing and has been continuously optimizing the mid-mounted motor ever since. The torque of 90 Nm still outclasses even significantly younger competitors. The drive's greatest quality, however, is evident above all in its natural handling and barely audible operating noise.

Kolmstetter: "In terms of its power delivery, the engine is still way out in front, has the best data in terms of power loss due to heat generation and was therefore clearly the first choice for us."
