ATTENTION, IMPORTANT NOTICE

Furthermore, driving a motor bicycle equivalent to a moped that does not comply with the aforementioned provisions will result in the administrative seizure of the vehicle and pecuniary penalties which vary according to the infringement committed. The manufacturer of the speed release system declines all responsibility relating to any damage caused to pedal assisted bicycles on which the device is mounted as well as direct or indirect damage to people or things.
