Wait, 20 km/h? That sounds way too slow for any vehicle on the road.

Momoka

Actually, that's exactly right! Specified small motorized bicycles must be unable to go faster than 20 km/h—it's one of their defining standards.

Hikari

Oh, so it's like a speed limiter built in?

Momoka

Yep! Think of it as a safety feature that keeps them in a different category from regular mopeds.
