<p>The vehicle (20) e.g. three-wheeled push scooter, has an electric pedal assistance that is provided in the form of an electric auxiliary drive (3). The electric auxiliary drive automatically switches itself only for a predetermined time at a predetermined power output for driving assistance. The auxiliary drive is switched based on a set of measurement or detection parameters such as detection of starting operation by a driver. The auxiliary drive is operated only within a predetermined speed window i.e. preferably between 6 and 25 km/h. The vehicle or skate board is constructed as a tri-cycle.</p> |
