Honestly 20km/h seems kinda slow. As a kid I’d do 20-25, and these days most European countries have a 25km/h limit on e-bikes. So 20km/h seems just low enough to be a hindrene.
Ultimately it depends on the bicycle lane or road though, just like for cars. There a huge difference between a crowded narrow inner-city cycle lane with immediate adjacent houses and other things obstructing vision, compared to a suburban cycle path with less traffic and completely unobstructed vision
