You could transport your folding bicycle as checked baggage, not as carry on, but would likely be charged a fee. While the weight is within the usual allowance for baggage, its dimensions would probably exceed airline restrictions.
Your bike (or example), the Anchor, measures 22β x 29β x 12β folded and weighs 30 pounds. Generally, airlines do allow such items, but usually require they be bagged or boxed (and limit liability as a condition).
The only way to know for certain whether you can, and any fees, is to contact the airline.
