Wouldn't work for germany, the limitation has to be implemented physically or enforced by the motor electronics. Which often get replaced by teenagers, with the consequence of loosing the allowance of the bike/moped and a hefty fine if it gets spotted. The police even picks them randomly out for checks more often because of this. Bicycles with electric boosters are allowed up to 25km/h and 250W. Everything above that needs a driver license in the EU - Class M if I'm not mistaken. And of course has to have a numberplate from your insurance. But most electric bicycles here in germany are limited to 20km/h, so that the rider isn't forced to wear a helmet by German law. (All km/h are meant without human power.)
