A continuously-variable planetary transmission including: (a) first and second spaced rotatable transmission elements spaced around a transmission axis and having first and second contact points, respectively; (b) at least one support element in fixed radial position with respect to the transmission axis and each having a third contact point; and (c) at least one elongate, rotationally-symmetric, rotatable planetary rolling element, each rolling element (1) contacting the transmission elements at the first and second contact points and each support element at its third contact point, the contact points each in frictional rolling connection to the at least one rolling element and (2) being supported by the first and second transmission elements and the at least one support element with freedom to move around the transmission axis; and (d) an adjusting device for displacing the center of each planetary rolling element to change the ratio of the transmission.
