Regarding ebicycles, which those regulations are for, I would prefer a acceleration based limit over a wattage based one. I am over 200lbs and my adult niece is probably 110/120lbs. That is a big difference for a small electric motor not even getting into cargo. Add in limits for battery size and bike weight for safety.

Regarding the brown wire issue. Couldn't they have just made it with 2 keys? A black for on public areas and a red one for private property?

Not sure the devices that are being describe in the article should be under class 1/2/3, but rather under a titled scooter category. Don't know if one exists though.
