Eco Drive

The two motor variants FM4.1 and RM5.1 can be combined with almost any rechargeable battery variants from the ANSMANN range. The standard installation size (100 / 135 mm) ensures that the mounting is uncomplicated and also enables any bike models approved under standard EN15194 to be fitted with this drive - even retrospectively.

The Eco Drive motors can also be combined with almost any hub and chain gear systems - the FM4.1 even with a back-pedal brake function. The integrated mechanical free-wheeling system ensures that no extra effort is required even without thrust from the motor.
