I've never heard of any place that required a license for any of the 3 formal electric bike classifications. If you need a motorcycle license that is because the thing you intend to ride is, in fact, a motorcycle.
The bike featured in the article, a BESV PSA1, is considered a "class 1" machine under the most common framework. It has a low-power motor, pedal assist, and no throttle. I am not aware of any place that requires licenses or insurance for such a bike.
Huh, I always thought that virtually everywhere treated these the same as motorbikes (ie you need a license, insurance etc).
