This is not what I would call a bicycle. It's a motorbike that allows you to pedal should you want to. In the UK, this would need a motorbike licence. There are strict rules as to how an electric bicycle may assist you and up to what speed. Non-pedal assist (just turn the handle) are limited to 20kmh otherwise they are considered a motorbike. Pedal assist are effectively self-limiting.

Also in the video, the woman accelerates away from a motorbike then loses him when she decides to carry on through a pedestrianised area at I guess 30kmh. WTF?

We have people at work who have electric bikes. The key is that they can be parked in bike racks with other bikes AND, most importantly, they can grab the battery and charge it at their desk.

Tyres are very fat on this bike so won't bike rack and the battery is internal so you will need a specific charging point.

As a bike for use on a mountain bike trail...bet the handling is way to heavy for most trails.

Clever idea but not sure who it's aimed at. I'm guessing an environmentally conscious dirt bike riders?
