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.
I think what does and does not belong on a bicycle path inside a city should depend on speed, size and weight. Some rules of thumb I just came up with; all measured in human sizes:
Scooter, longboard, skateboard, inline skates, boosted board, whatever? Sure, come on in. We’re about the same speed, size and weight, so we can intermingle just fine.
Big fat cargo “bicycle” with a huge-ass storage container on the back? You belong on the road.
If the motorcycle in question is lightweight, small and not very fast, I wouldn’t mind it in the bike lane though.
The style you’re suggesting is a bit too heavy (surprisingly just 223 kg but still too much) and obviously way too fast.
If it was lighter and had a 20-30 km/h speed limit though, I probably wouldn’t mind too much. It wouldn’t be much different from a cargo bike and those have proven to work just fine in bicycle paths.
