A variable speed drive (37) is described, comprising: a ring (60) adapted to rotate about a first rotation axis; two coaxial disks (73), rigidly connected to each other, adapted to rotate about a second rotation axis (B-B) parallel to the first rotation axis; wherein the ring (60) is at least partially housed between the two coaxial disks (73); a plurality of driving members (75), carried by the ring (60) and arranged according to a circular arrangement coaxial to the ring (60); said driving members are arranged and configured to cooperate with opposite surfaces (73A) of the two coaxial disks (73), transmitting a rotation motion from the ring (60) to the two coaxial disks (73); a device for adjusting the distance between the first rotation axis and the second rotation axis. A drive device (17) of an assisted-pedal human-powered vehicle (10) which includes such a drive is also described.
