The MAHLE Ebike Motion X35 and X35+ engines are designed specifically for e-road bike. The innovative Ebike Motion X35 and X35+ engine is a hub engine with only 40Nm of torque. In contrast to the conventional engines that provides assistance based on cadence or power input the Mahle engines the outputs power is based on how quickly the cassette is turning relative to the hub. This design means the Mahle drive can be tricked into riding with basically no input from the rider. As long as you keep the cassette and hub turning together, the motor continues to push forward – there’s no torque sensor to detect your lack of pedalling input as the system operates based on the speed of your cassette in relation to how quickly the wheel is turning.
In 2022, Mahle released the new Ebike Motion X20 drive unit following the foot steps of other manufacturers developing a more powerful and lighter engine. In fact, the Ebike Motion X20 motor delivers a torque of 60Nm (50% more torque than the X35 motor) and weights only 3.2 kg (10% lighter than the X35 motor).
There aren’t many tunings available in today market to derestrict the X35 and X35+ engines. The EPAspeed engineers have excelled in developing the tuning for the Mahle engines because as for today it is the only tuning that retains the accuracy of the speed on both the e-bike display and on the Ebike Motion App. Moreover, it allows for speed up to 40kmh depending on the motor, firmware, and battery of your drive system. However, due to the limitation of the hub motor and the 40Nm of torque it is acceptable that speeds will be in the 30kmh range.
The SpeedFun does really do a good job for its quality of built and for its slim feature but it does not retain the accuracy of the travelled speed.
NOTE: Due to the constructive characteristics of the hub motor with the speed sensor integrated into the hub motor it is difficult to predict the maximum derestricted speed allowed. Theoretically, speeds of up to 40 km/h are possible but in reality speeds of up to 30 km/h are within the tolerance range. This is due to the fact that it is a hub motor with 40 Nm of torque which quickly reaches its limits. If the tuning does not allow for higher speeds, this is not caused by the tuning itself but instead it is related to the limitations of the motor, battery and their firmware.
EPAspeed Mahle Ebike Motion X35 and X35+ real speed value from the display (if you bike is equipped with one) and from the Ebike Motion App. Easy to install / remove. Can allow for higher speed depending on your e-bike battery, firmware, and engine configuration but 30kmh is in the acceptable range.
SpeedFun Ebike Motion X35 Easy installation that plugs directly on the speed sensor cable on the swing arm. Does NOT retain the speedometer accuracy on the display and also on the Ebike Motion App.
As for today, no tuning manufacturer has developed a tuning device for the Ebike Motion X20 motor.. but I can assure that they must be currently working on it..so if you are waiting to get your Ebike Motion X20 engine derestricted just subscribe to our Facebook blog or our Newsletter for updates on the release date.

J’ai un Orbea M30 avec le système X35 : moteur dans le moyeu central de la roue arrière … que me proposez vous ?
Hello Grega, at the current moment there is no tuning available for the X20 engine. We will post an update on our FB page once the tuning becomes available
Hello! I have a scott adict30 bike with a mahle x20 engine. I wonder if you have a speed unlock for my bike? Thank you
