Ampler electric bikes do not have energy recovery/recuperation.
For e-bikes with recuperation, the energy generated is fed back into the system and used by the engine. However, the energy gained is only marginal.
Another big downpoint would be that motors, who do recuperate energy, a resistance is always felt when the motor is off.
In order for our motors to be small, silent, lightweight, powerful and our bikes easy to pedal without support, we’ve decided not to offer recuperation on Ampler electric bikes.
