The photo example is PreColumbian, as a matter of fact. :’) The presence of the wheel is known, but the wheel was not observed to be in use when the Spanish and Portuguese, French, English, and Dutch got here. Even the use of metals was mostly limited to decoration. OTOH, in Tiahuanaco there was metal smelting and some use of metal in construction.

The horse-drawn farm wagons,and other wheeled machinery that I used during my pre-teen and teen years on Minnesota and Wisconsin farms were equipped with either a simple straight round steel shaft or, in the case of hay wagons, wooden or steel beams fitted with tapered cylindrical sleeves at each end around which the wheels rotated. None had ball or roller bearings, although that single tapered sleeve might be deemed a unitary roller bearing. Ha, Ha).
As for draft animals to pull a wagon, dogs have been used for that purpose, and American Indians used ponies, if available, in lieu of women and children to pull a pair of wooden poles (skids)on which folded-up tepees and housekeeping goods were piled. (Or so I’ve seen in the movies).
