Steel Big Wheel Mystery

I found this steel big wheel in the trash on the Upper East Side and of course had to pick it up. I have often wondered about its origins,but have been too lazy to actually track it down, but thanks to Daddytypes, I don't have to. He posted this rickshaw:
for sale at modern50. A few quick googles later I found that the company, Angeles, is still making products. Thanks Greg!

update: Go figure, a site called, Tricyle Fetish, has a whole bunch more info about the company Angeles, history and a couple cool shots of their products. Go check it out.
