Airline Baggage Regulation / Flying with Bikes

Interesting:

If the bicycle(s) are packed in a container that is less than 50 pounds (23kg) and 62 (158 cm) total linear inches (L + W + H), there is no bicycle service charge, but, if applicable, the first or second checked baggage service charge applies.

How did you manage to get under 158cm? I would have though a bike without couplers would be bigger than that? My bike bag is at least 200cm in total, if not more.
