This is what I'm getting at though. If we start saying one of the problems with overpowered illegal ebikes is that they're silent, if any future changes in the law to deal with these things includes the noise issue, those same rules might also be applied to those of us who ride perfectly legal ebikes and non ebikes because they too are silent or near silent.
And maybe we shouldn't taint the owners of such less than legal ebikes with the same brush either.
My own bike unrestricted will currently do 23.5 mph under throttle. I've fitted a smaller chain ring. With the original ring I had 25 mph out of it and I have no doubt whatsoever that with a bigger ring, 30mph would also be easily achieved. I've ridden it quite a few times unrestricted and it took no more than a cable and free software to do that. It's not exactly difficult. Does that then mean I'm a law breaking low life with no regard for anyone else's safety? Not really. I wonder how many of us have lived squeaky clean lives?
How do we deal with the not so legal versions of ebikes? No idea. I originally had an idea of making these things and overpowered motor kits being illegal to sell to the public unless one could show they had a licence and insurance. To my horror, I today found out its perfectly legal to buy a car without a licence or insurance.
