Well the bike would have to first pass through a scanner like other luggage so objects hidden in the frame will probably raise suspicion. However, a person can do more harm to someone with a disposable ball point pen (the "Glock" of shivs) than a small pocket knife yet they're not even considered a weapon, so yeah, TSA rules aren't necessarily about being sensible.
