An electrically-assisted pedal cycle drive system comprises an input 80 that receives drive from a pedal of the cycle and an output that provides drive to a driven wheel of the cycle. An electrical machine 5,6 provides motor drive. The drive train comprises an epicyclic gear set having a sun gear 21, a planet carrier 23, a plurality of planet gears 22 and an annulus gear 24 that rotates with the output. The epicyclic gear set transmits drive from pedal to its annulus via its planet carrier 23. The sun gear 21 is driven by the electrical machine 5,6. The drive train also comprises a one-way clutch V between the planet carrier 23 and a fixed part of the drive system 1, to allow rotation of the planet carrier 23 in only one direction.
