The issue I see with this approach is that it doesn’t really account for differing views on what constitutes acceptable limits in terms of speed, power, and usage.
Let me give you an example.
I grew up in Italy, where at the time, like in other countries, I guess, there was a vehicle category known as
“ciclomotori” (mopeds). These were extremely popular, especially among teenagers. Getting one was almost a rite of passage: on your 14th birthday, you were expected to start insisting with your parents that you absolutely
needed one to fit in socially. And usually you succeeded (like in my case...

)
This category included vehicles up to 50cc, around 1.5 hp, with a top speed of 40 km/h. Remarkably, they could be driven from the age of 14. Models like the Vespa or the Ciao and Bravo Piaggio were part of this group. Unsurprisingly, strong industrial lobbying (notably from Piaggio) played a role in shaping the regulations.
Note: at the time (I’m referring to the 1960s–70s), there was no digital electronics to enforce limits internally. No license plate, no insurance, no formal license, being 14 was enough. Because these vehicles were small and agile, enforcement was already difficult for the police.
Here’s the problem: I don’t recall a single “ciclomotore” among my friends that was actually compliant with the rules. Modifications were extremely easy: adjusting the carburetor or making small mechanical tweaks could push these vehicles to 80–90 km/h or more.
However, the frame, brakes, and, most importantly, the maturity of the riders (myself included

) remained unchanged.
The result was a very high number of accidents and fatalities. A slaughter, actually.
Eventually, in the 1990s, legislation had to evolve to better protect the public: license plates were introduced, along with clearer rules and the requirement for a so-called "AM license".
In many ways, current EU regulations for pedelec e-bikes seem designed to anticipate a similar problem. The principle is straightforward: if you want to ride something classified as a bicycle but equipped with a motor, that’s fine, but beyond a certain point, the motor assistance simply stops. Modern digital electronics make this (relatively) easy to enforce.
Of course, we can debate where those limits should be set, or how they should be verified. But conceptually, the system is simple, at least in much of the EU.
One could imagine introducing more complex rules, with exceptions depending on context or location. But is that really practical? In Italy, the real issue at present is often something else: a well-known, widespread tendency to disregard
rules, combined with relatively low levels of enforcement. And this is not limited to this specific case, it applies to many aspects of everyday life.
After that, we could spend the next 100 years debating these limits, or whether it makes sense to go for a “free-for-all” approach in this area, or instead introduce systems where “here you can do whatever you want, and here you can’t.” But the real question is: is this actually realistic?
Personally, unfortunately, I don’t think so.
If you want to ride fast on a bike, then you should have insurance, a license plate, and pass a test to prove you’re capable of doing it safely.
For yourself and for the whole community. And if I catch you riding at 70 km/h on a bike path, you should be in serious trouble.
Honestly, I don’t see any other way out. The usual argument about “responsible use” doesn’t seem to work, or to have ever worked, in any field. We are just too many, and 1% of "unresponsabile" people would be a thread to the whole community.
