MAHLE Launches New M40 eMTB System
MAHLE SmartBike Systems officially enters the eMTB market with the M40 System, a compact, lightweight and powerful mid-drive motor designed for full control and high-performance off-road riding.
Full Power, Full Control
With 105 Nm of torque and 850 W of peak power, the M40 motor delivers high responsiveness even under the most demanding conditions. Designed specifically for mountain and trekking bikes, it adapts seamlessly to the rider’s cadence and effort, offering smooth, natural support and precision performance.
Lightweight System, Heavyweight Performance
The M40 drive unit weighs just 2.5 kg, setting a new benchmark in power-to-weight ratio at 340 W/kg. Combined with the iM5 battery (534 Wh), the total system weight remains around 5 kg, making it one of the lightest full-power eMTB systems available.
For longer rides, the iM8 battery (800 Wh) delivers up to 150 km or 2 500 m of elevation gain.
