I ride my 6kw ebike in city parks, along the river pathway, along city pathways, park pathways all the time. Not once has a person clued in that my regular looking bicycle has a motor in its rear hub. I hide it very well, its hidden behind some pannier bags, and the controller blends in camoflauge style to the rear rack. The batteries are located inside the pannier bags. I've even had police officers behind me while I ride 60kph on the roadway. Now when I move fast up a hill with my feet noticably off the pedals, I get stares and that is on purpose
I've asked countless gassers on bicycles if they have any hassle, and everyone said nope!
If I were to start blowing past people on the pathways, pissing people off, doing wheelies, scaring people, scaring kids, scaring family pets then someone would phone it in. The most thats happened so far, are people who jump when they are scared or frightened. Its happened a lot, I guess they aren't used to the noise of a trapezoidal wave controller and the sound it makes, obviously different then the sound of a geared motor, whether it be geared hub or geared mid drive.
I figure if I hide the motor, and allow it to have good airflow on a trailer, making it a pusher trailer and gearing it properly. I think along the highways and byways of Alberta and BC, there should not be an issue at all. Of course I will do some fake pedaling when I see the 5-0 aka The Fuzz aka The Pigs aka The Donut Eaters, but I will play it by ear.
I will be respectful and ride at a reasonable rate of speed in a safe manner.
Here was a quick search and a quote
"In a decision this month, the court detailed how Alejandro Calderone was pulled over in 2013 by an officer who heard sounds coming from his powered-bicycle’s small gas engine and saw exhaust puffing out from the back."

"It’s an issue that has come up before. In 2013, North Vancouver RCMP issued a warning after receiving complaints of youth riding bikes with gas engines."
So a licence and insurance is whats needed, I will ask around Alberta Insurers if they insure gas powered bicycles. I doubt they do.
Sounds to me like the pig in Kelowna had a hard on, and his ticket quota was quite low. Either way, on the highway, trying to make it real silent will be a goal of mine.
