Wheeled...thing

[Papaw]

Not motorcycle wheels- too narrow and no provision for brakes.

22.5 inch rims are really uncommon. (unheard of) Common bike rims are 20" 26" 27" and now 29" along with 700MM for road bikes.
24" is a standard as well but uncommon.

If you are measuring total outside diameter you would need to subtract the tire mounting surface, that would make it an actual 21.5" tire/rim....never seen it.
possibly metric at 550mm but that would be very, very odd/old.

It does look just like the rickshaws, and clamping diferent "bodies" on a common undercarrige makes sense.

Based on pawpaws pictures and other pictures I looked up earlier today I am thinking rickshaw.

Very near find.

Wheels seem too small, and attachment point too high for a rickshaw, and why make it fold up??  I still go for a set of wheels for transporting some thing, folds up to save storage space when not in use...

Just Googled, 22" rims are available as well

European sizes 457 mm 22" x 1.75; x 2.125 see: http://sheldonbrown.com/tire-sizing.html

I helped a friend build something very close to this for moving his 20' teepee and poles. We went with out springs at first but was hard on the poles, so we added buggy springs.

I have a question, on that folding (kick stand).   Is it one legged?   Or is the second broken off?   If it were a rickshaw, and the leg of the kick stand was to the rear, it would keep it from toppling over backwards, the weight of the shafts would keep it leaning to the front the rest of the time.

   Whatever its origins, I'd say before that was dumped out back some lucky kid had a goat cart a few decades ago.
