I don't know about Amazon, but $200 is the price of a reasonable entry-level bike in any large surface store so yes?

I know this is HN and people will likely look down on anyone riding a <$2000 bike, but come on.

No, there are much better under-$200 bikes on craigslist. :P Get a nice $100 bike from the early 80s and pay a bike store for a tuneup, and you've got a pretty useful bike to ride on all day; gotta friction shift though. Not a lot of great looking wheelchairs on craigslist near me though.
