Motor

What kind of motor does the bike have?

All Ampler bikes have a small geared hub drive with a brushless DC motor, branded by Ampler. The motor has a nominal power output of 250 W, but it can be tuned up to 350 W via our smartphone application. The peak power output of the motor is about 450 W. The motor is compliant with all European regulations.

What is a torque sensor?

Ampler bikes are pedelecs and they have sensors regulating the motor, measuring the speed and your own input. Therefore, the bike is easy to use and the motor power is controlled according to your own pedalling force. This creates a safe and smooth riding experience.

Is there any motor resistance?

The motor has a built-in free-wheel, which means that there’s no resistance from the motor when the motor is not helping (for example, when your battery is empty or when you’re going faster than the assistance speed limit you’ve set).

Does the motor recuperate energy?

No, it does not.
