Eco Drive
Our recommendations for



Suitable motors
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.
