What does “flyer” mean in slang, and how is that different from the printed document?
The word “flyer” can refer to an advertising circular, while “take a flier” can mean taking a speculative or risky venture FLYER Definition & Meaning – Merriam-Webster. In informal use, “take a flyer” also describes doing something that could have a good or bad outcome definition in the Cambridge English Dictionary. The printed meaning concerns a piece of promotional material; the slang meaning concerns risk.
The Flyer(TM) Duoflex 2 in 1 is neither of those things in its listed function: the Amazon listing describes a bike trailer and double stroller Flyer(TM) Duoflex 2 in 1 Bike Trailer and…. The product name may invite a word-definition detour, but the listing provides no evidence that the name refers to a paper circular or a risky undertaking.

Should the product name be spelled “Flyer” or “Flier”?
The product name spells the first word “Flyer,” so the Flyer(TM) Duoflex 2 in 1 should be named with that spelling rather than silently changed to “Flier” Flyer(TM) Duoflex 2 in 1 Bike Trailer and…. That settles how to write this listing’s name. It does not settle which spelling you should prefer for the general word.
For the general word, both “flyer” and “flier” are accepted spellings, and style references differ in their preferences Flier or Flyer? Learn the Difference.

Its poster examples are larger, including 18 by 24 inches and 24 by 36 inches Flyer vs Poster: What’s the Difference?. Those figures describe printed materials only; they say nothing about the dimensions of the Flyer(TM) Duoflex.
Purpose and layout differ as well: flyers often carry concise, actionable information, while posters use bold visuals and minimal text for quick viewing Flyer vs Poster: What’s the Difference?.
