The mid-mounted motor with torque measuring is mounted instead of the left crank. 

Due to its construction and position on the bike, it provides a natural riding feeling and is absolutely noiseless. 

With an output of 250 watts and a maximum torque of 65 Nm, it supports your pedalling performance up to a speed of 25 km/h (legally permissible maximum value for EU countries). 

As the motor doesn't have a gearbox, there is no noticeable pedalling resistance when the battery is switched off.
