An electric kick scooter is a small platform with two or more wheels that is propelled by an electric motor. Besides the motor, propulsion can also happen by the rider, pushing off to the ground. The most common scooters today have two hard small wheels, are made primarily of aluminum and fold for convenience. Some kick scooters have 3 or 4 wheels, or are made of plastic, or are large, or do not fold. High performance trickster scooters made for adults resemble the old "penny-farthing" with much larger wheel in front. Electric kick scooters differ from electric scooters in that they also allow human propulsion, and have no gears. Range is typically about 5 km, and maximum speed is around 30 km/h.
