I don’t have the data to back it up, but as someone who lives in the Netherlands I can tell you that e-bikes definitely seem like a problem. People who ride a normal bike to go somewhere definitely don’t go faster than 15 kph on average. You totally can do so if you want, just like you can run everywhere instead of walking, but then you might arrive sweaty and out of breath. E-bikes allow people who don’t usually have the physical strength to cycle that fast to suddenly go 25 kph without much effort. Especially children and elderly are a problem. The bikes are heavy, meaning that they’re hard to control for these groups. And children and elderly also both often lack the awareness of their surroundings needed for driving this fast. I’ve seen many dangerous situations where these groups on an e-bike yeet into a crossing, suddenly have to brake due to other traffic that they failed to account for, and then almost fall over or crash.

E-bikes have a way too large speed difference with normal bikes, and imo they’re definitely a danger. Anything that makes them slower is imo a good thing.
