I can appreciate why you and many would want ebikes to specifically NOT be otherwise regulated, and treated ONLY as a plain old bicycle. there is a lot of advantage to that for ebike owners if the definition and also legislation , regulation on use, etc stopped there.
But while the general definition of a “bike” CAN find a way to include both standard bicycles and ebikes on the general terms, 2 wheels, components, pedals, etc, that does not mean the two are identical in operation and use, or identical in max speed, safety, etc…. there may even be situations like age where some might be concerned (6 year old on banana seat huffy vs. 6 year old on “class 3” Super 73 or some such thing)
I’ll admit i’m a pessimist, my worry in removing the 3 Class system is that my state and other states would replace it with their own new and more onerous classification, establishing more significant restrictions on how i use my ebike because i know how govt acts and wants to control things, have a thumb on things, likes to prohibit things….
perhaps i am naïve, but i cannot see the direct harm, to me or other riders in my state as a result of 3 class system thus far. But i can see potential harm if it is removed and replaced by something else that some legislator felt pressure to propose because we lacked any differentiation between the motorized and non-motorized versions, and having that be even less of a national standard than 3 class is as a semi-national standard many states have already adopted .
(having said this i know you will say “there is no difference, the CPSC says so” and i’d agree as it relates to the CPSCs jurisdiction, but i’d also argue that states won’t feel any different about closing/opening trails and ways to ebikes, requiring registrations or insurance, etc. it is the law of unknown consequences.
How can you guarantee nothing but good will come to all of us from removing 3 class?
Aside from a guarantee, why are you so confident that nothing but good can come from it?
What other situations can you remember where govt was involved and where nothing but good came from it?
