M40 System

Description
MAHLE M40: Maximum power, minimum weight. A new generation of mid-drive systems
Designed for the most demanding riders and perfected down to the last detail, the new MAHLE M40 system marks a new era in eBike electrification. Built to deliver powerful performance in a lightweight, highly agile package, it redefines what full-performance eBiking means.
Uncompromising performance
Weighing just 5.2 kg, the M40 stands out as one of the lightest full power systems on the market. It delivers 105 Nm of torque, up to 850 W of peak power, and a 400% assistance ratio, achieving a leading power-to-weight ratio of 340 W/kg.
Advanced range and efficiency
With a range of up to 150 km or 2,500 meters of elevation gain, the system maximizes every watt to strike a unique balance between lightweight design, extended range, and sustained power. (Figures may vary depending on rider, terrain, environmental conditions, and season.)
Smart and natural assistance
An ultra-precise speed sensor on the rear wheel enables smooth and controlled power delivery, adapting seamlessly to the rider’s cadence and effort to ensure a natural and fluid riding experience—free from jerks or sudden surges.
Smart features for any terrain
• Smart Disengagement: seamless transition between assisted and unassisted pedaling with zero drag.
• Motor Dynamic Overrun: provides momentum after pedaling stops, ideal for clearing obstacles smoothly.
• Hill Brake: automatic motor hold on inclines for safe and stable starts.
MAHLE ecosystem: compatible and scalable
The M40 is fully compatible with the MAHLE X series, offering a scalable system tailored to different rider needs. It also introduces new components developed specifically for this platform:
• Trio: a compact, wireless, and intuitive remote.
• Head Unit+: a sleek 1.9” color display with BLE connectivity and multiple mounting options.
• iM5 and iM8 batteries: high-performance 48V batteries with fast charging (up to 80% in under 3 or 4.5 hours), compact and powerful.
• Innovative charging port and state-of-the-art speed sensor, detecting speed changes in under 3 cm of movement for unmatched precision.
Sleek design and full integration
MAHLE’s engineering expertise has enabled the miniaturization of key components, resulting in a discreet yet powerful system. Full compatibility with X and M drive platforms, accessories, and chargers ensures a seamlessly connected and durable eBike experience.
