Sadly, existing legislation cannot provide an unambiguous answer to this question. The current version of the traffic rules have no definition of an e-scooter. The closest-related definitions are bicycles and the mopeds. A bicycle is defined by the following parameters: speed of up to 25 km/h, can be fitted with a motor with a rated maximum power for continuous running of up to 250 W, and is driven by a person's muscle power. A moped can hit up to 50 km/h, is driven by an electric motor, and equipped with an engine with a rated maximum power for continuous running from 250 to 400 W.
In our opinion, Whooshbikes are the closest to the definition of a bicycle. The speed is limited to 25 km/h, it can't go any faster. They are physically set in motion by the user, the engine will only start if you push off with your foot and reach a speed of 3 km/h. The Whooshbikes' motors are different, with a 250-watt rated maximum power for continuous running. In addition, you can comfortably climb uphill with the help of the engine, and it can also be used for braking, because in addition to the mechanical one, the Whooshbikes also have an engine brake. The electric motor is also used to limit the speed when driving downhill, to maintain a maximum speed of 25 km/h — since the speed is limited, it will not be possible to hit more than 25 km/h on our scooters.
