I am curious if existing bikes would be "grandfathered" in, without a specific clause about that?
If not, there might quite a few retail-sold bikes (or built from retail-sold kits) that don't meet the new specs and would have to be modified.
BTW, this bit in that article
“This bill is a critical step for Arizona in clarifying the law surrounding the use of e-bikes, and will encourage the safe use of e-bikes by providing clear rules with respect to how they must be equipped and operated,” she added
is silly, because all of that was already clear with the existing law. Just didn't have a power limit.
Personally, I doubt that enforcement is going to care about power levels as long as they are ridden safely and within the law.
If I end up having to limit mine to 750w, well, it's going to piss off a bunch of drivers out there, and make it a lot less safe to ride anywhere, simply because of acceleration times (and if there is any wind, because 750w isn't even enough to go 20MPH in still air on the trike because of it's lack of aero).
I have the CAv3.1 already on there and setup, so just have to connect the throttle to it, then the rightside system will all be under it's control for PAS and throttle, so by itself it would be max of 750w. Can't connect the leftside system until I can design and build the electronics to keep throttle usage independent so I can still steer via throttle to make tighter turns, yet still allow the CA to limit things to a total of 750w.
I have no idea how to do that yet. Can't use two separate CAs because that won't limit to a total of 750w automatically between whichever motors are being used, unless both CAs use the same single shunt, so they can each see the total power. But how they will be able to regulate when each has no feedback to the other besides that.... Moot as I don't have a second working v3 CA anyway (just an old 2.3-something).
