Because if you're an e-bike, it's purely legal, not a bike anymore. It's not an S-pedelec, either. It's just illegal.
There are differences to an E-bike and a S-Pedelec. Closer we are in ours E-bike guide received. Here you can get a lot more information about the differences and the constructions.

What is an e-bike dongle?

A dongle makes the bike computer think it is too slow and has air open up to help you pedaling. Most dongles start at 15 km / h and halve the speed. This means you will be supported by your bike instead of 25 km / h to 50 km / h.

Installation E-Bike dongle

Each bike is a bit different during assembly and you will get with each dongle a suitable guide either on the device itself or on the Internet.
Mostly the dongle is mounted in front of the speed sensor so that it can manipulate the speed there.

Magnetic box e-bike

If you do not feel like screwing half a wheel apart, it can make your bike faster in another way. A small box is pushed on the rear wheel between the spokes - done.
What is she doing there? A magnetic sensor intervenes and manipulates the speed of the bike. Manufacturers of this type indicate that the part can be removed and removed in seconds without leaving a trace.
What's up? Your bike can push up to 40 km / h. But even here your speedometer no longer shows the real speed.
