System that limits e-bike speeds will be tested on Dutch roads

Tests conducted outside Amsterdam’s Schiphol Airport could slow fast s-pedelecs.

I wonder how that system would work. Would it transmit a wireless signal to the controller or something? I just don't understand how they could do it. What do they do about road bikes which can go those speeds with the right rider?
