A pedal cycle drivetrain (1) comprising: an epicyclic gear train (3) comprising: a sun gear (11) rotatable around a main axis; a planet carrier (13) rotatable around the main axis and carrying one or more planet gears (15) meshed with the sun gear (11); and an annulus (17) rotatable around the main axis and meshed with the one or more planet gears (15). The sun gear (11), the planet carrier (13), and the annulus (17) are each exclusively in direct drive with one of: an input (5) including one or more pedals; an output (7) including a wheel hub (8) rotatable around the main axis; and a first electric motor (19). Varying angular velocity of the first electric motor (19) corresponds to a varying effective transmission ratio between the input (5) and the output (7). An example application for the pedal cycle drivetrain (1) is use as a transmission in a human powered vehicle (100, 200, 400) such as a unicycle, a recumbent bicycle, or a tricycle.
