The San Francisco Bicycle Coalition weighed in with a pointed response, arguing that the state should be making it easier, not harder, to own and use e-bikes. Their senior organizer echoed the sentiment shared by many riders: the real confusion and danger comes from people not being able to tell the difference between a legal e-bike and an electric moped, not from the bikes themselves.
Brett Thurber, co-owner of a San Francisco e-bike shop, raised a practical industry concern about AB 1557. Restricting California’s speed limits below what manufacturers currently build for the U.S. market could push companies to skip California customers entirely, shrinking the supply available to local shops and consumers.



Oh, but I did find a (German) source for my question right now: “According to estimates by police and experts, five to ten percent of e-bikes in Germany are tuned.”
I am cautious of trusting a police union on this without any source, but it is at least something.
So now you can specify: “Less than 10% of e-bike riders remove or know a guy to remove the limiter”, since of course this was an estimate on tuning in general.

But your facts based on data were for other questions, questions I didn’t ask, you do realise that? If I had asked how many fatbikes were illegally fast, you’d have nailed it, but it didn’t answer anything on if they were tuned or not.
I know it is only an estimate, but why are you being so hostile about that? I had a specific question, you found some sources that showed related facts, but nothing on your original claim. I appreciate that effort. I now find a rough estimate, do you have a reason to doubt it? Why?
I believe at this point, you are just being angry at me for the sake of it. Take a breather, I assure you everything I wrote was genuine, I am just particular about this 1 question. If you don’t see the point, that’s fine.
I am not entirely satisfied with an estimate either, but it is something to go off.
