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.
Responsive Assistance, Seamless Riding
Thanks to advanced sensor technology, the M40 offers smooth motor response without abrupt peaks. Features like Motor Dynamic Overrun and Hill Brake enable controlled starts on steep climbs and precise trail handling.
