Oof...
So, it looks like a couple of potential issues. I'm seeing photos of bikes with 4-bolt and 5-bolt cranks. However, I'm seeing that the bike comes stock with 84T front, 14T rear.

However, everything says "tiny teeth", but nothing seems to be listing the actual sprocket pitch.
So, going from 84T to 64T would be much lower gearing.
So, any idea what the chain type/pitch is?
Here are some notes about chain pitch:

64T, #35, and #219 gocart rings are relatively common, and not too expensive. The trick would be to adapt the gocart ring to a bicycle crankset.

Another option might be seeing if one could replace the rear sprocket with one slightly larger. Say 16T or 18T. The clearance around the rear chainstays also looks tight, so going bigger could be an issue.
