Slapping a 200cc motor in a bicycle effectively makes it a motorcycle. And it might just be my opinion, but I don't think I'm far out of line to say anyone's bicycle with a 200cc motor in it is a flimsy motorcycle/scooter.
No one has a "right" to put whatever engine they want on a bicycle and go riding down the road. There's a clear line between what is and what isn't.
Freedom only goes so far, and those who willingly take unfair advantage of it end up making it worse for many others in the long run.
What he said^
Motorized bicycles are a gift of mutual benefaction if kept small, within the scope of legal regs and resistant to the mission creep of turning them into fake motorcycles. Human nature being what it is though, I don't hold much hope for that kind of commonsense to be all that prevailing.
