Mahle, the German brand renowned for its hub motors, has entered the mid-drive motor market. The M40 comes with some pretty impressive specs, with 105Nm of maximum torque and 850W peak power - something that rivals the recent offerings from Bosch, Specialized and almost DJI. The new motor also signifies Mahle's intent to wrangle its way into the electric mountain biking segment - something the old X systems failed to do.
