The disclosure relates to a continuously variable transmission (CVT) unit. The CVT unit comprises a first drive element that is rotatable about a first axis and a second drive element that is rotatable about a second axis parallel to the first axis, wherein the first drive element and the second drive element are movable relative to each other in a direction transverse to the first and second axis. The CVT unit further comprises first coupling elements provided at a constant first radius from the first axis and at a variable second radius from the second axis, for transferring torque between the first drive element and the second drive element.
