Actually, it is a bicycle touring forum. The words "human powered." do not appear in the forum description. The forum description says:
The definition of a bicycle is in statute. It is not whatever we want to pretend it is. Because of this, trikes are also treated as Bicycles, while they are clearly not, by strict definition, bicycles. People here like to throw out terms like Motorcycle, motor-driven cycle, and moped; however, they pretend ignorance that these terms have legal definitions that are not the same as the definition of an e-bike. In fact, many of these statutes specifically exclude e-bikes from their definitions.

Now, whenever it is pointed out that the definition of a "bicycle" is a matter of statute, some sophomoric bloke will present the question "whose statutes" After all, the laws vary throughout the globe." The answer remains quite simple. The statutes that apply are the statutes in the jurisdiction where it is being applied. This means that if I am in Kansas, I apply Kansas statutes. If I am in KSA, I apply KSA statutes.
