M40 System
Powered for the Wild
Meet the MAHLE M40, our new full‑power mid‑drive, engineered to give riders instinctive, fully capable control in any terrain.
Pure Power, Unmatched Weight.
The new M40 full-power drive system offers full control, power and high efficiency even in demanding environments and even at high support levels and cadences. The M40 weighs just 2.5 kg and generates an impressive torque of 105 Nm and a peak power of 850 W.
Absolute Control from Firmware to Sensors
The M40’s advanced control unit and high-resolution speed/torque sensors ensure instant power delivery the moment you start pedaling. In practice, the M40 responds smoothly even during sudden cadence changes.
Dynamic control logic fine-tunes output on the fly, so the M40 anticipates and executes the rider’s intentions without delay.
Our flagship speed sensor (detecting speed variations within less than 3 cm) works alongside cadence and torque sensors to ensure near-instantaneous response to every pedal stroke.
