In my country we have these:

This is a dvoukolák (lit. twowheeler). According to the internet it can carry up-to 240 kg. Dvoukoláks often have bigger wheels and they’re not collapsible.

I looked on American Amazon and on Walmart’s website and I couldn’t find anything like it. Bike trailers seem to be closest to a dvoukolák.
