Shimano STEPS E6100 motor (DU-E6180)

The Shimano STEPS E6100 is a compact and efficient mid-drive e-bike motor, specially designed for comfortable everyday rides, commuting and extended trekking tours. With a maximum torque of 60 Nm and a rated continuous power output of 250 watts, the drive unit provides smooth and natural pedal assistance. Whether in city traffic, on longer cycle tours or on inclines – the motor ensures a comfortable and controlled riding experience.
Thanks to its energy-efficient drive concept, the Shimano STEPS E6100 utilises the available battery capacity particularly efficiently, thereby supporting a long range.
