Electric vehicles with a throttle (what the law is targeting) can absolutely be used as motorcycles. Hence why CA feels motorcycle-like vehicles need to be reclassified. What the law is targeting are functionally motorcycles/mopeds with pedals attached.

Perhaps with your preferred brand(s) of ebikes. This law is targeting Super73 and similar brands that advertise and promote post-sale “off-road” or “unlimited” modifications. These modified bikes have been a nuisance on public trails for a few years now.

Here in Melbourne, Australia, they use them like motorcycles everywhere.

Every single food panda, or other delivery rider is on an e bike with throttle, and they never peddle.

They ride at full speed, on the roads, like motorcycles.

It’s totally doable. Thousands are doing it every day here.
