I hate to muck up the Canadian waters, but I thought somebody from Calgary was talking about how the "electric" folks had messed up the definitions for everybody. But the "under 50 cc" bikes were under the radar.
Or maybe it was that electric guy in the Wikipedia entry, who somehow made HIS the only type that slipped through the legal crack.
I really wouldn't know how you could get a transferable title to a bike without a Vehicle ID # stamped on it.
