Being a life long motorcycle nut I'm amazed such a thing as a China Girl motor bicycle exists and I didn't know about it. Not just me either. None of my riding friends has ever heard of them either. I'm not talking about all motorized bicycles. Only China Girls. I've been aware of electric bicycles, and kits to motorize a bicycle for years, but never had any interest what so ever until I saw my first China Girl. How long have you known about China Girls?
