Today, while out running errands on my hybrid, I saw an e-motorbike (this style) using the bike lane (dude also had a motorcycle helmet on).
Personally, I think these people should stay on the road like other motorbikes, as it’s clear that these are supposed to be an electric analog to ICE powered bikes.
I called this person out as well, due to my position being they actually are more of a hazard to other cyclists and pedestrians when the lanes switch to MUP’s without warning. Especially where they would be heavier than even e-bikes and would cause anyone they hit more damage than they would receive.
The class system is designed for these arguments. I’m fine with class 2 in lanes and paths, but now we can discuss ebikes and where they belong without confusion. And regulators for parks, towns, etc can make it very clear in their signage.
