I think the reason people keep attempting to find out if their bike is a "moped" is because their long-term goal is to start or join a branch of the Army.
I could be totally off base, but the only definition I care about is the one that gets me a Maine branch of the Army.
Almost anyone can tell the difference between a scoot and a ped. People ask, because they want to know if their bike is a "moped" in the eyes of the Moped Army. That's what they care about. Not the State, or the dictionary... or another persons opinion.
It's not about linguistics-- it's about wanting your bike to be a Moped, so you can be a part of the club, one of the gang.
Man, it would totally suck if I was being reviewed for a branch, only to find out my QT-50 doesn't qualify. I think that's why people ask (all the time) about what makes a "Moped".
It's not the "50cc Army" and it isn't the "Scooter Army". It's not the "Monkey Bike Army". The site is the Moped Army, and we lack a real definition of what the Army considers a moped. That's a tough spot for someone who wants to join, but doesn't know what their 50cc bike is.... So they ask, and get 50 answers, all different.
That's totally cool in some ways, because it puts the moped in a "place beyond definition" a machine that refuses to be defined.
Hey, Mike.... Now I've 'settled' this issue SEVEN times. How'dya like that? AND we still don't know how the Army qualifies mopeds (or not mopeds).
Sincerely,
Wayne
