M40 System performance testing with the media
At Mountain Bike Connection Winter 2026, a Bike Connection Agency dedicated press event, specialised media had the opportunity to ride market‑available eBikes powered by the MAHLE M40 System. The event focused on hands‑on testing, allowing journalists to experience the system in real riding conditions while also exploring new M40 functionalities that will be released próximamente.
By combining real production bikes with in‑depth technical sessions, Mountain Bike Connection Winter 2026 provided a clear and transparent environment for understanding how the M40 System performs today and where it is heading next.
eBikes Present at Mountain Bike Connection Winter 2026
The MAHLE M40 System was showcased on production eBikes from several brands, all available on the market:
- Abums
- Alpek
- Kristall
- Sants
- Titan
- Unica
Testing the system on complete, commercially available eBikes allowed the media to evaluate integration, riding behaviour and system response exactly as end users will experience it.
MAHLE M40 System Overview
Powered for the Wild, the MAHLE M40 is a full‑power mid‑drive system designed to deliver instinctive control, high efficiency and consistent performance across demanding terrain.
Despite its full‑power capabilities, the M40 stands out for its low weight and compact design, enabling bike brands to build capable eBikes without unnecessary bulk.
Key Performance Figures
- Motor type: Mid‑drive with integrated smart controller
- Motor weight: 2.5 kg
- Maximum torque: 105 Nm
- Peak power: 850 W
- Power density: 340 W/kg
- System voltage: 48 V
Absolute Control: Sensors and Software
The M40 System combines a high‑performance control unit with advanced sensor technology to ensure immediate and predictable assistance.
- High‑resolution torque and cadence sensors provide instant power delivery from the first pedal stroke.
- An ultra‑precise speed sensor, capable of detecting speed changes within less than 3 cm of movement, enables accurate and responsive assistance control.
- Dynamic control logic continuously adjusts output, ensuring smooth behaviour even during sudden cadence changes.
The result is a system that reacts naturally to rider input, without delays or abrupt power transitions.
Signature Control Features
Two core features define the riding experience of the M40 System:
Motor Dynamic Overrun
Allows the motor to continue delivering controlled assistance briefly after pedalling stops, helping riders clear obstacles and maintain momentum on technical sections.
Auto Hold
Holds the bike securely on steep inclines, preventing rollback and supporting safe, controlled starts on climbs.
Displays, Remotes and System Components
The M40 ecosystem includes dedicated components developed specifically for the M‑Series:
Head Unit +
Compact control unit with a 1.9” colour LCD screen, multiple mounting options and support for BLE and ANT+.
Trio Remote
Wireless three‑button remote for flat handlebars, enabling intuitive system control without removing hands from the bar.
Ultra‑precise speed sensor
Designed to maximise system accuracy and responsiveness.
M40 System: Built for Real‑World Riding
The Mountain Bike Connection Winter 2026 press event highlighted the MAHLE M40 System in its intended environment: real production eBikes, real riders and real conditions. By combining full‑power performance with precise control, low weight and a dedicated ecosystem, the M40 defines the starting point of MAHLE’s new M Series.
Together with the X Series, the M Series represents MAHLE SmartBike Systems’ next generation of eBike solutions, designed to support a wide range of riding styles and use cases.
Stay tuned to discover the new M40 functionalities coming soon.
