Maybe I could carry one of the bags with the wheels, handlebars, and seatpost as carry-on, assuming they are not interpreted as lethal objects (I've never heard of an attempted highjack using 20'' bike wheels or padded handlebars).
Assuming a standard weight limit for carry on of 50 lb or 22 kg, I usually come out at 48 to 49.5 lbs with bike and case. Close, but it adheres to their regulations. I've never had a problem yet. I use a scale at home obviously to check prior to leaving. All bike components are in the hard case, including my helmet and a judicious selection of tools, which you usually can't bring on board as carry on.
I think you would have some difficulty boarding with wheels, seatpost, etc., especially a seat post. Long, hard, metal objects could be interpreted as weapons. I know they usually question my tripods for photography, even if they're small ones.
