The lance is normally a two handed weapon. There is a special rule allowing you to use it one handed while mounted. A large creature can use a two handed weapon that is sized for a medium creature one handed. This next part is a bit of interpretation... when mounted you sort of become a combined creature with your mount, since your mount is (usually large) that lets you use the two handed weapon (lance) with one hand.
