It may be based on a bicycle and have an electric motor, but the vehicle in that video is not a class 1, 2, or 3 e-bike. Due to the speed and motor size (2 kW) most places would classify it as an electric motorcycle and require the corresponding license. The limit to be considered a class 3 e-bike (in the US), the highest e-bike class, is a maximum speed of 28 MPG on level ground with standard passenger + cargo mass before the assist cuts out. (You may be able to exceed that speed with pure pedaling, or on a downhill slope.) Class 1 and 2 are limited to 20 MPH, with only foot-controlled throttle ("pedal assist") or the option of hand-activated throttle, respectively. All three classes are limited to 750 watt or smaller motors. Quite a few places treat class 3s as motorbikes or motorcycles rather than bicycles.
