Goodmorning SB,
There are very strict rules in the Netherlands on motorized bicycles, either with an electric motor or a gas engine.
ebikes:
ebikes can be built or bought if they are limited to the motorized speed of 25 kph (15 mph), that means that you are allowed to pedal faster than 25 kph, but the motor has to shut off completely above this speed.
i.e. you have to have a so-called pedelec sensor installed, which shuts off power completely over 25 kph..... That is the reason why ebikes overhere are referred to as "motor assisted" bicycles. The emphasis is still on pedalling.
Electrical bikes are really popular now amongst elder people who still use a bicycle (and there are millions of elderly cyclists in the Netherlands).
The ebikes sold in stores are all equipped with a pedelec sensor. These bikes do not have to be insured or to carry a registration and license plate.
My own ebike is not equipped with this mandatory sensor and runs a little over 50 kph (31 mph), and that makes it pretty much illegal. (48 Volts, 1000Watt battery)
But since Amsterdam is a crowded and old city, there is hardly ever an opportunity to reach the top speed! And when I see a policeman, I just pedal a bit and nobody knows the difference....
I actually doubt that this subject is in the right thread, maybe I should move this elsewhere.
