Like its counterpart in the rear, the RM5.4, the FM4.2 front motor delivers quiet and vibration-free power directly to the road. Thanks to the integrated mechanical freewheel, no additional effort is required even without motor thrust. When using the front motor, a hub gear in the rear and the coaster brake can also be installed.
The RM5.4 also has a speed pickup in the motor and a motor position sensor. The sensor data can be transferred to the display or other devices via the interfaces. With the optional use of Battery Intelligence, you also make your bike fit for the digital future and for use in fleet and rental / sharing systems.
