BRAKE ASSISTANT
Before a trip, the brake assistant can be activated.
It supports you during braking and ensures energy is fed back into
the battery (if it is not charged above the threshold of 90 % and
the temperature is not below 0 °C). During active recuperation or
with active brake assistant, always be ready to brake (using the
existing bicycle brakes).
